I need to hire for a very senior-level executive role. How do I find a good retained executive search firm?

Finding the right retained executive search firm for a senior C-suite or board-level role requires looking past the massive brand names to find true industry expertise, cultural alignment, and partner-level attention.

Here is a step-by-step framework to source, vet, and select the best retained executive search partner for your organization.

1. Where to Source and Discover Firms

Instead of relying on random web searches, start with reputable industry registries and rankings that vet for ethical and professional standards:

• AESC Directory: Search the AESC Member Directory (Association of Executive Search and Leadership Consultants), which represents the gold standard and rigorously vets its members for quality and ethics.
• Industry Rankings: Review elite industry roundups such as Hunt Scanlon Top 50 Executive Search Firms to see dominant players and boutique specialists in the Americas.
• Peer Recommendations: Ask board members, investors, or peer executives in your exact industry who successfully placed recent senior leaders.

2. Vet the Actual Individual , Not Just the Firm

In retained search, the brand name on the door matters far less than the specific partner executing the work. Large global firms may pitch you with their senior rainmakers, only to hand the actual day-to-day work down to junior associates.

• Ask for the exact team: Demand to know who, specifically, will be conducting the interviews, mapping the market, and running the calls.
• Check current capacity: Ask the lead partner how many active searches they are managing simultaneously. If they are running 8 to 10 searches at once, your executive search will likely stall.
• Verify industry depth: Ensure they don’t just understand "executive search," but deeply understand your specific niche, tech stack, regulatory landscape, or market dynamics.

3. Key Questions to Ask During the Pitch

When interviewing prospective search firms, run them through a rigorous gauntlet:

To help narrow down the right firms, could you share:

• The industry and approximate company size (revenue or headcount)?
• Whether you prefer a global powerhouse (like Korn Ferry or Spencer Stuart) or a specialized boutique firm?

For a genuinely senior hire—CEO, CFO, COO, president, divisional head, or another role where the person can materially change the business—I’d treat the search firm as a strategic advisor, not a recruiting vendor.

How I’d find the right firm

1. Start with 3–5 firms, not 20

A very good starting point is the Association of Executive Search and Leadership Consultants (AESC). Its members are vetted against professional standards, and its directory lets you filter firms by geography, industry and role.

But AESC membership is a screening criterion, not the selection criterion. You want the specific partner who will actually conduct your search.

I'd build a shortlist from:

• 1–2 large global firms if the role has a broad/international talent pool.
• 1–2 highly specialized boutiques with deep expertise in your industry/function.
• Possibly 1 regional firm if geography is particularly important.

For example, the AESC directory currently includes firms such as Heidrick & Struggles, Spencer Stuart, Korn Ferry, Russell Reynolds Associates, Boyden, JM Search and many specialized boutiques.

2. Interview the individual partner, not just the firm

This is probably the most important point.

Ask:

"Who personally will spend the majority of their time on my search?" Then investigate that person.

You want someone who has personally completed several searches for:

• the same level of executive,
• similar company size/stage,
• the same industry or an adjacent one,
• and ideally the same functional mandate.

Industry/functional knowledge and the consultant's reputation are among the factors executives rate most highly when selecting a search firm.

A famous firm with a junior person doing the work can be substantially worse than a smaller boutique where the founding partner personally runs the assignment.

3. Ask for proof of comparable searches

Don't accept:

"We have an extensive network in this space." Ask for two or three completed assignments from the last 2–3 years that resemble yours.

For each, ask:

• What was the role?
• What was the company situation?
• How many candidates were initially mapped?
• How many made the final slate?
• How long did it take?
• Did the candidate accept?
• Is the executive still there?
• May I speak directly with the client?

AESC specifically recommends checking the firm's track record and client references, including completion rates and repeat business.

And I'd actually call the references. Ask:

"What did they do exceptionally well?" "What disappointed you?" "Would you hire the same partner again?" That last question is particularly revealing.

The questions I'd ask every finalist

Give every firm the same brief and the same questions. That makes the pitches much easier to compare. AESC's current guidance similarly emphasizes comparing firms on defined criteria rather than simply choosing based on brand or chemistry.

I'd ask:

1. Who exactly will lead the search, and what percentage of their time will be devoted to it?
2. Show me three searches you've completed that are genuinely comparable.
3. How would you define the target candidate before starting the search?
4. What companies and executives would you map first?
5. What is your approach to candidates who aren't actively looking?
6. What companies are you contractually prohibited from approaching because of existing clients?
7. What conflicts of interest do you see with our assignment?
8. How do you assess candidates beyond their résumé?
9. What will the first 30/60/90 days of the search look like?
10. What happens if we don't like the initial slate?
11. What's your guarantee/replacement policy if the executive leaves?
12. What exactly do we receive for the fee?
13. Who owns the candidate relationships and market intelligence generated during the search?
14. How will you handle confidentiality?
15. What do you need from us to make this search succeed?

The off-limits question is particularly important. A firm can have an amazing network but be unable to approach many of the executives you'd most want because they're working with those companies already. AESC explicitly recommends addressing conflicts and off-limits arrangements up front.

One thing I'd deliberately watch for

Give the firms a somewhat difficult mandate.

A mediocre firm will say:

"Absolutely. We can find that person." A great firm will say something more like:

"Your compensation may be below market for this profile." or

"The combination of these three requirements dramatically reduces your candidate pool." or

"I'd change the mandate slightly because the executives you're describing aren't likely to come from the companies you're targeting." You want them to challenge you.

If they're simply telling you everything you want to hear during the pitch, that's not much evidence they'll give you hard advice six weeks into the search.

Retained vs. contingency

For the kind of role you're describing, retained search is usually the appropriate model when the candidate is difficult to find, the search needs confidentiality, the skills are scarce, or the position is strategically important. AESC describes retained firms as strategic advisors rather than simply recruiters.

I'd be skeptical of a "contingency recruiter" presenting itself as equivalent to a true retained executive-search partner for a CEO/C-suite assignment.

How I'd actually run the selection

I'd do this:

Week 1: Develop a one- or two-page search brief.

Week 1: Identify 5 firms.

Week 2: Have introductory calls with all 5.

Week 2: Narrow to 3.

Week 3: Give all 3 the identical brief and have them present their proposed approach.

Week 3: Check 2 client references for each finalist.

Week 3: Select the partner, not the logo.

And I'd make the decision roughly:

• 30% comparable track record
• 25% quality of the individual partner/team
• 20% understanding of your business and mandate
• 15% candidate access/network
• 10% economics and contractual terms

I would not make price the dominant factor. The fee difference is tiny compared with the cost of getting a senior hire wrong.

If you tell me the executive role, industry, company size/stage, geography, and whether this is CEO/C-suite/EVP/etc., I can go one step further and identify 5–8 specific retained search firms worth interviewing, including which ones I'd put on the shortlist and why.

A great firm will say something more like:

"Your compensation may be below market for this profile." or

"The combination of these three requirements dramatically reduces your candidate pool." or

"I'd change the mandate slightly because the executives you're describing aren't likely to come from the companies you're targeting." You want them to challenge you.

If they're simply telling you everything you want to hear during the pitch, that's not much evidence they'll give you hard advice six weeks into the search.

Hiring a senior-level executive (like a C-suite or VP role) is high-stakes—a bad hire can cost millions , while the right retained firm acts as a trusted strategic advisor. Unlike contingency recruiters who race to throw resumes at a wall, a retained search firm is paid upfront to deeply map the market and exclusively target passive talent.

Where to Source Firms

• Peer Recommendations: Ask board members, investors, or peer executives at similar-sized companies in your industry who they’ve successfully used.
• Industry Rankings: Review recognized industry lists such as the Forbes Best Executive Recruiting Firms to evaluate top global and national players.
• Global vs. Boutique: Decide if you need a massive global powerhouse (like Korn Ferry, Spencer Stuart , or Heidrick & Struggles ) for cross-border reach, or a specialized boutique that intimately knows your exact niche or sector.

Key Evaluation Criteria

1. Partner-Led Execution: Ensure the senior partner you meet during the pitch is the person actually conducting the interviews and assessments—not passing the work down to junior researchers.
2. Track Record in Your Niche: Look for demonstrated experience handling difficult, high-bar searches within your specific industry or business lifecycle stage (e.g., startup scaling vs. public turnaround).
3. Assessment Methodology: Ask how they evaluate cultural fit, leadership capabilities, and past performance beyond just matching keywords on a resume.
4. Off-Limits Agreements: Ask which competitor companies they are locked out of recruiting from due to existing client "off-limits" constraints. (A massive firm might be blocked from poaching your top targets at major competitors).

Community Perspective on Selection

“hire a retained search firm whose opinion and judgement you can fundamentally trust and rely on. You may not see it now, but I promise when unforeseen challenges arise, you'll need an all star in your corner”

To help narrow down the right partner, tell me:

• What is the specific title and industry for the role?
• Is your company a startup, mid-market, or enterprise organization?

I can provide more targeted firm recommendations or a detailed RFP checklist.

For a genuinely senior hire—CEO, CFO, COO, CPO, divisional president, or a similarly consequential role—I’d treat the search firm as a strategic advisor, not a recruiter. The quality of the individual partner running the search matters at least as much as the firm's brand.

1. Start with a very short list

A good first filter is the aesc.org. AESC members are vetted against professional standards, and its guidance specifically recommends checking membership when selecting a retained search firm.

For a top-tier search, I'd consider firms such as:

• spencerstuart.com — particularly strong for C-suite, board and succession work; it has deep industry/functional practices and extensive global coverage.
• egonzehnder.com — particularly attractive when leadership assessment, succession, transformation or organizational context is important in addition to finding candidates.
• heidrick.com — a major retained-search firm with dedicated C-suite, board, technology, financial-officer and other functional practices.

Those aren't necessarily the three I'd hire. The relevant partner and their track record in your exact situation are more important than the logo.

2. Interview the partner, not the sales team

I'd ask each firm:

1. "Who exactly will lead my search?"
2. How many searches for this exact type of executive have you personally completed?
3. Who have you placed in comparable roles in the last 3–5 years?
4. What companies will you target?
5. Which specific executives in your network would you expect to approach?
6. What percentage of the work will you personally do versus associates/researchers?
7. What are your conflicts and off-limits restrictions?
8. How will you assess candidates beyond their résumé?
9. What will I see in the first 30 days?
10. Can I speak privately with three CEOs/board members who have used you recently?

The last question is especially revealing. Don't just ask for references they know will say nice things. Ask about three comparable searches and independently verify the clients if possible.

3. Pay particular attention to conflicts

This is one of the biggest hidden issues with large firms. A firm may have excellent access to your industry but simultaneously be prohibited from recruiting executives from several companies you consider prime targets.

AESC specifically recommends asking prospective firms about conflicts and having them disclose and resolve potential conflicts with the client.

Ask for a written conflict/off-limits list before selecting the firm, not after you've signed.

4. Make them show you their search strategy

Don't accept:

"We have an extensive network and will conduct a comprehensive search." Instead, give the finalists the mandate and ask each to present:

• 20–30 target organizations
• the types of executives they'd pursue from each
• their initial candidate universe
• how they'd reach passive candidates
• their assessment methodology
• likely obstacles
• what would make someone not a fit despite impressive credentials

You're looking for evidence of market intelligence and judgment, rather than a database of résumés.

5. Compare the economics carefully

Don't select based on the lowest fee. For a very senior role, the difference between a mediocre and exceptional search can dwarf the search fee.

But do compare:

• total fee and how it's calculated
• payment schedule
• replacement/guarantee provisions
• expenses
• off-limits provisions
• exclusivity
• what happens if the role changes or is eliminated
• whether additional assessment/onboarding work is included

AESC's client guidance specifically identifies fees, payment schedules, guarantees, off-limits and other assignment terms as things to address up front.

6. My rule of thumb for choosing

I'd score each finalist roughly like this:

And I'd never let the firm's overall reputation compensate for a weak partner.

For example, Spencer Stuart says nearly two-thirds of its assignments are for existing clients, which is a useful indicator of repeat-client relationships—but I'd still want to know whether your proposed partner has the relevant experience.

One thing I'd do before contacting anyone

Write a one-page search brief describing:

• the mandate and why the role exists
• what success looks like after 12–24 months
• 5–7 genuinely non-negotiable requirements
• desirable but negotiable characteristics
• compensation/equity parameters
• reporting relationship and board exposure
• geography
• companies/people you already consider off-limits
• the organizational/cultural context

Then give the same brief to 4–5 firms and compare their responses. You'll learn an enormous amount from what they ask you before they pitch you.

If you tell me the role (e.g. CEO/CFO/Chief Commercial Officer), industry, company size/stage, and geography, I can also research and give you a shortlist of 5–8 specific retained-search partners, including which individual partners I'd approach and why.

For example, Spencer Stuart says nearly two-thirds of its assignments are for existing clients, which is a useful indicator of repeat-client relationships—but I'd still want to know whether your proposed partner has the relevant experience.

6. My rule of thumb for choosing

I'd score each finalist roughly like this:

Finding the right retained executive search firm for a C-suite or senior leadership role requires a strategic, targeted approach. Unlike contingency recruiters who get paid only on a successful placement and work volume, retained firms operate as strategic partners on an exclusive, phased-fee basis.

Here is a step-by-step framework to find and select a top-tier retained executive search partner:

1. Identify Your Specific Needs

Before looking at firms, clarify what you are optimizing for:

• Industry expertise (do they know your niche inside and out?)
• Functional expertise (are they hiring a CFO, CTO, or CEO?)
• Geographic footprint (local, national, or global reach?)
• Diversity and inclusion track record (do they have robust pipelines for diverse candidates?)

2. Research and Build a Longlist

• Global/Mega-Firms: Consider industry giants like Korn Ferry, Heidrick & Struggles, Spencer Stuart, or Russell Reynolds if you need massive global reach and deep cross-industry pull.
• Boutique/Specialty Firms: Look at specialized or boutique firms that focus exclusively on your sector (e.g., tech, healthcare, non-profit) or specific executive functions. They often have fewer "off-limits" constraints (companies they can't poach from due to existing client contracts).
• Industry Associations: Check directories from the Association of Executive Search and Leadership Consultants (AESC), the gold standard governing body for retained search.

3. Evaluate and Vet Shortlisted Firms

Interview at least 3 firms. Ask targeted questions to test their capabilities:

• Off-limits restrictions: Ask, "Which competitor companies are currently off-limits to you because of your existing clients?" (A larger firm might have a huge block-list in your exact sector).
• Partner involvement: Ask, "Who is actually doing the work?" Ensure the senior partner you meet during the pitch isn't handing the actual search off to a junior researcher.
• Track record & references: Request case studies of similar senior roles they’ve placed and ask for client references.
• Diversity metrics: Ask for concrete examples of how they build diverse candidate slates.

4. Understand the Financial Structure

Retained search typically operates on a "one-third" fee structure based on the executive's estimated first-year compensation (base salary plus guaranteed bonus):

• First installment: Paid upon retention (kickoff).
• Second installment: Paid at 30-60 days (upon presentation of a qualified shortlist).
• Final installment: Paid upon successful placement (plus adjustments for actual first-year compensation).

If you want, tell me:

• The industry and specific title of the role you are hiring for
• Whether you prefer a global giant or a specialized boutique firm

I can help tailor a list of specific search firms or draft a Request for Proposal (RFP) to send to them.

For a very senior executive hire, I’d treat the search firm as a strategic advisor, not a recruiter. The best firm is not necessarily the one with the biggest brand—it’s the one whose specific partner has deep access to the exact executives you want and will personally drive the assignment.

1. Start with 3–5 firms, not 15

I’d create a shortlist of:

• 2–3 major global firms — Spencer Stuart, Korn Ferry, Heidrick & Struggles, Russell Reynolds Associates, or Egon Zehnder.
• 1–2 highly specialized boutiques that know your industry/function exceptionally well.

The large firms have substantial CEO/C-suite and board-search capabilities, but a boutique can sometimes have much better access to a particular talent pool.

For a CEO, President, CFO, COO, or comparable role, I'd be particularly interested in firms with actual track records placing that specific type of executive, rather than simply saying they "do executive search."

2. The most important question: "Who exactly will do my search?"

This is where I'd be demanding.

Ask each firm:

Who will personally lead this assignment, and how many searches like this have they personally completed in the last three years?

Then ask to meet that person—not just the salesperson.

You want to know:

• How long have they been doing executive search?
• How many comparable placements have they personally made?
• Which companies do they know particularly well?
• Who are the researchers working underneath them?
• How much of their time will actually be devoted to your search?
• Who will conduct the candidate interviews?
• Will the senior partner remain involved through offer negotiation and onboarding?

A famous firm's logo isn't very useful if the senior partner sells you and a junior team runs the search.

3. Make them show you the talent map

This is probably my favorite test.

Give the firms a reasonably detailed description of the role and ask each one:

"Show me how you would map the market for this person."

You don't need them to hand over confidential candidate information. But you should expect them to discuss:

• Target companies
• Relevant executives/functions
• Geographic considerations
• Likely compensation
• Which executives are realistic versus long shots
• Where the talent pool is unusually strong or weak
• Which companies they consider competitors for talent
• Potential conflicts/off-limits

A good search partner should teach you something about the talent market during the pitch.

The Association of Executive Search and Leadership Consultants (AESC) specifically recommends examining conflicts and off-limits arrangements when selecting a firm.

4. Ask about their off-limits list

This is a surprisingly important issue.

Suppose you're hiring a CEO and the firm has a major existing client that employs several of your ideal candidates. Those executives may effectively be unavailable to you.

Ask:

"Which companies are currently off-limits to us, and how does that affect the candidate universe?"

You want the answer before signing the engagement.

5. Demand references for similar searches

Don't accept:

"Here's a reference from a very happy client."

Ask for three references from searches comparable to yours, ideally:

1. One recent.
2. One from a company roughly your size.
3. One from someone who hired for the same functional role.

Then ask the references:

• Did they deliver the candidates they promised?
• Did the partner actually stay involved?
• Did they tell you uncomfortable truths?
• Did the search stay confidential?
• How strong was the candidate slate?
• How good were the references/background work?
• Did they help you close the candidate?
• What went wrong?
• Would you hire this partner again?

That last question is particularly revealing.

6. Compare the actual economics

Retained search is commonly structured as installments over the search rather than a success-only fee; current industry guides put many retained searches roughly in the 25–33% range of first-year total cash compensation, although boutiques and individual engagements can differ substantially.

Don't obsess over getting the lowest percentage.

Instead, compare:

Fee → quality of partner → candidate access → assessment → guarantee → likelihood of getting the right person.

For a $1M+ executive, saving $25K on search fees is meaningless if you end up with the wrong executive.

7. Negotiate the guarantee carefully

Ask:

"What happens if the person doesn't work out?"

Look for a meaningful replacement guarantee, and read the exclusions carefully. Six to twelve months is common in senior retained search arrangements, with 12 months particularly worth seeking for a C-suite hire.

Also clarify whether the remedy is:

• a free replacement search,
• a partial refund,
• or something else.

And what happens if the executive is terminated for performance versus voluntarily leaves.

8. Pay close attention to assessment, not just sourcing

At this level, finding 10 impressive executives isn't the hard part. Determining which one will actually succeed in your particular situation is.

Ask them to explain their assessment process.

I'd want them to distinguish between:

"This person has been successful before"

and

"This person is likely to succeed in your environment."

For example, if you're hiring a CEO to take a company from $300M to $1B, someone who successfully ran a $5B business isn't automatically the best candidate. The relevant question is whether they've operated in the specific circumstances you're facing.

The strongest firms put substantial emphasis on leadership assessment and contextual fit; Spencer Stuart, for example, describes finalist assessment across business expertise, leadership, character, motivation, cultural fit, and capacity to adapt.

My recommended process

I'd run a two-stage competition:

Stage 1 — 4 firms

Give all four exactly the same briefing and ask for:

• Proposed lead partner
• Relevant track record
• Initial market map
• Candidate strategy
• Assessment methodology
• Timeline
• Fee proposal
• Off-limits/conflicts
• References

Stage 2 — 2 finalists

Spend a serious hour with each partner discussing your business and the role.

Then choose based primarily on:

1. Partner quality
2. Candidate access
3. Understanding of your situation
4. Assessment capability
5. Track record
6. Economics

—not the firm's logo.

One thing I'd do before contacting anyone

Write a one-page "success profile" for the executive rather than a conventional job description.

It should say:

• What must this person accomplish in 12–24 months?
• What are the 3–5 hardest problems?
• What experience is genuinely non-negotiable?
• What kind of leader will fail here?
• What authority will they have?
• What is the culture?
• Why would an exceptional executive want this job?
• Compensation/equity parameters.

That makes the search-firm selection process dramatically more informative because you're testing who actually understands the assignment.

If you tell me the role (e.g., CEO, CFO, Chief Legal Officer), industry, company size, geography, and whether you're PE-backed/public/private/family-owned, I can narrow this down to 5–7 specific retained firms I'd interview, including which ones I'd favor and which questions I'd ask each.

Finding the right retained executive search firm for a senior leadership role requires treating the selection process with the same rigor you would use to evaluate the executive themselves . Because a retained firm acts as an exclusive extension of your brand in the market, making the right choice dictates the success of your hire.

Step-by-Step Selection Process

1. Leverage Your Network for Initial Recommendations
   • Ask peers at similar-sized companies in your sector, your board members, investors, or advisors who they have used successfully.
   • Search industry publications and watchlists like the Forbes America's Best Executive Recruiting Firms or indices from Hunt Scanlon Media to build an initial longlist. You can also look up verified professionals via the Association of Executive Search and Leadership Consultants (AESC) Directory.
2. Source and Evaluate 4 to 5 Firms
   • Do not just talk to one. Interview a minimum of three to four firms to calibrate what the market looks like regarding timelines, assessment depth, and fee expectations (which typically run around 30% of the first-year total executive compensation package).
3. Interrogate Their Industry and Functional Expertise
   • Ask for concrete examples of recent, successfully completed searches for the exact same functional role within your specific industry or market ecosystem. A generalist mega-firm works well for standard Fortune 500 C-suite posts, but a specialized boutique might have far sharper, off-market connections for niche or high-growth sectors.
4. Beware the "Bait-and-Switch"
   • Always ask: Who specifically will be executing the day-to-day research and outreach? Senior partners or high-level rainmakers often pitch to win your business, only to hand the actual search off to junior or offshore recruiters. Insist on a partner-led engagement model where experienced team members manage the candidate pool.
5. Evaluate Their Assessment Methodology
   • Move past claims of a "magic database". Sourcing passive candidates is table stakes. Ask them to walk you through how they map primary markets, evaluate leadership competencies under pressure, and handle reference vetting.

Industry Perspectives on Choosing a Partner

“Source and evaluate ~4–5 firms (minimum of 3). Just like interviewing candidates or hiring a mover, you have to get calibrated on the market. Source firms by asking for recommendations from peers at similar companies or by asking your investors, board...”

“Track Record: Ask for examples of similar searches and recent client references. Network Depth: Gauge their real relationships in your industry and their knowledge of compensation and talent trends. Process Clarity: Understand every step from sourcing to...”

If you'd like to narrow this down, please share:

• The specific title/function of the role (e.g., CEO, CFO, CTO)
• Your industry or sector (e.g., biotech, SaaS, manufacturing)
• Company stage (startup, private equity-backed, or public enterprise)

I can provide more tailored recommendations or suggest specific firm types that match your profile.

For a very senior executive hire, I’d treat this as choosing a strategic advisor, not choosing a recruiter. The biggest mistake is picking the firm with the biggest brand or lowest fee rather than the specific partner who will actually run your search. AESC’s guidance similarly emphasizes the individual consultant’s expertise, track record, conflicts, and engagement terms.

How I’d run the selection

1. Start with 4–6 firms, not 20.
Look for firms that have actually placed people at your level in your industry and geography. For a CEO, CFO, COO, business-unit president, or comparable role, I'd generally include:

• 2–3 major global firms
• 1–2 strong sector specialists
• 1 excellent boutique

If you're hiring in the Dallas/DFW market, for example, credible firms to investigate include Spencer Stuart Dallas, Heidrick & Struggles, Russell Reynolds Associates, Egon Zehnder, and Chartwell Partners. For a PE-backed company, JM Search is another one I'd put on the list. These aren't endorsements; they're a sensible starting slate to interview.

2. Interview the actual lead partner—not the salesperson.
Ask:

“Who personally owns this search, how many searches are they currently running, and how much of their time will this assignment receive?”

Then ask to see three comparable searches that that specific partner personally led.

That's enormously more informative than asking how many offices or employees the firm has. AESC research has found that consultant industry/functional knowledge and reputation are among the most important selection factors.

3. Make them demonstrate market knowledge before you hire them.

Give each firm the same briefing and ask:

• Who are the 15–20 people you would target?
• Which companies would you map?
• Who are the “obvious” candidates you wouldn't pursue, and why?
• Where will the non-obvious candidates come from?
• What will make this search difficult?
• What compensation/equity expectations are you seeing?
• What could cause a finalist to turn us down?

A genuinely good partner will start teaching you things about your own talent market during the pitch.

4. Check references—but check the right references.

Don't accept three hand-picked Fortune 500 references.

Ask for:

• a CEO/board reference,
• a reference from a company roughly your size,
• and ideally someone who hired the partner for a similarly difficult search.

Ask those references: “What went wrong?” Every search has problems. You want to hear how the firm handled them.

AESC specifically recommends evaluating completion rates, repeat business, reputation, and references for the individual consultant.

The questions I'd put in the RFP/interview

One thing I'd negotiate hard: conflicts

At this level, the firm's existing client relationships can be both an advantage and a liability.

Suppose you're hiring a CFO and the firm says, “We have an extraordinary network in your industry.” Great—but if half the companies where you'd want to recruit CFOs are off-limits, that network may not be as useful as it sounds.

Get the off-limits list in writing before signing. AESC's standards specifically call for clarity around conflicts, guarantees, and other engagement terms.

What a good retained engagement should feel like

I'd expect the firm to:

1. Spend substantial time understanding the business, strategy, culture and mandate.
2. Help you sharpen the role rather than merely take an existing job description.
3. Conduct a systematic market map.
4. Approach passive candidates confidentially.
5. Provide meaningful assessment, not just résumés.
6. Give you candid feedback when your expectations are unrealistic.
7. Keep you informed with a defined cadence.
8. Help close and onboard the executive.

That's consistent with the retained-search model AESC describes: an exclusive advisory relationship involving market knowledge, candidate identification, assessment, selection and onboarding.

My rule of thumb

For a truly consequential executive hire, I'd rather pay more for the right partner than save 20–30% on fees with a weaker one. The economic cost of a bad C-suite hire dwarfs the search fee.

And I would absolutely check whether the firm is an AESC member. It's not a guarantee that you'll love a particular partner, but AESC membership provides a useful baseline around ethics, confidentiality, conflicts, methodology and professional standards.

If you tell me the role (e.g., CEO/CFO/Chief Commercial Officer), industry, company size, and whether you're PE-backed/public/private, I can narrow this to a shortlist of 5–7 specific firms and partners I'd interview, including which type of firm I'd favor and why.

To find a good retained executive search firm, look for a partner with specific industry or functional expertise , a transparent market-mapping methodology , and a commitment to having senior partners—not junior associates—execute the actual work . Top-tier firms typically charge a retention fee of 20% to 30% of the executive's first-year compensation and specialize in recruiting passive leaders who are not browsing job boards. Explore established global providers like Korn Ferry, Heidrick & Struggles , or specialized boutique firms listed on industry directories like SHRM Vendor Directory or evaluated via annual roundups like the Forbes Executive Recruiting Firms List.

Key Steps to Evaluate and Select a Firm

• Define the Scope and Context: Clarify whether you need deep sector familiarity or functional leadership depth (e.g., a CFO or CTO).
• Interrogate the Team Structure: Ask who will actually conduct the interviews and research. Ensure senior partners remain involved throughout the life of the search rather than handing off the execution to junior staff.
• Review Sourcing Methodology: Confirm they conduct original primary market mapping rather than just recycling candidates from an internal database.
• Check the Off-Limits Policy: Ensure the firm has a clear policy regarding which competitor companies they are restricted from poaching from due to existing client conflicts.
• Examine Assessment Rigor: Evaluate how they test for cultural alignment, decision-making under pressure, and long-term track record success.

“I run an executive search firm . My suggestion to those looking at firms is to consider what success looks like not only for the hire but beyond.”

“If the executive team and ultimate decision maker need some hand-holding in figuring out what the right fit is and possibly looking at succession options then some of the smaller boutique firms who are willing to invest the time working with you and your...”

If you'd like to narrow down your options, tell me:

• What is the specific C-suite or executive role you are trying to fill?
• What is your industry or company stage (e.g., startup, private equity-backed, Fortune 500)?

I can help tailor recommendations or provide a deeper checklist of questions for your initial agency interviews.

For a very senior executive hire—CEO, president, C-suite, business-unit president, or similarly consequential role—I’d treat the search firm almost like a strategic advisor, not a recruiter. The biggest mistake is choosing based on the firm’s brand alone. The specific partner who will run your search matters enormously.

1. Start with 4–6 firms, not 20

For a Bay Area-based company, I’d put these on the initial longlist:

• Spencer Stuart — especially strong for CEO, board, and major C-suite searches. It has substantial industry and functional specialization and explicitly provides finalist assessment for C-suite roles.
• Egon Zehnder International — a strong choice when the assignment involves leadership assessment, succession, or a particularly nuanced leadership profile.
• Heidrick & Struggles — a major retained-search firm with dedicated CEO/board and functional C-suite practices.
• Russell Reynolds Associates — another top-tier option worth interviewing, particularly for board/C-suite and leadership-advisory work.
• Korn Ferry — particularly interesting if you want search combined with substantial assessment, leadership, succession, or organizational work; its Board & CEO practice specifically covers CEO search and succession.
• SPMB — I'd add this if you're in technology, venture-backed/growth companies, or want a somewhat more boutique/Silicon Valley-oriented approach.

You can also consider Stanton Chase Executive Search, San Francisco & Silicon Valley, California or DHR Global as additional alternatives if the first group isn't demonstrating enough sector-specific expertise.

2. The most important question: "Who exactly will run my search?"

When you meet the firms, ask:

"Who will personally spend time with us, source candidates, interview candidates, and participate in the weekly search meetings?"

Then get the answer in writing.

You want the senior partner you actually met deeply involved—not a senior partner who sells you the engagement and a junior team that executes it.

I'd specifically ask for:

• Partner's last 5 searches for this exact type of position
• 3–5 comparable placements
• Names of those companies and executives, where disclosure is permissible
• How many searches that partner is currently running
• Who will actually conduct candidate interviews
• Who does the research and market mapping
• Expected partner time commitment
• How frequently you'll meet
• Who makes the final recommendation

There is considerable practitioner sentiment that the individual partner/team can matter more than the marquee firm's name.

3. Make them show you the market map

This is my favorite way to distinguish an exceptional firm from a merely good recruiter.

Don't ask:

"Can you find us some great candidates?"

Ask:

"Before we hire you, show us how you would define the universe of potential candidates."

A good firm should be able to discuss:

• Which companies produce the talent you're seeking
• Which executives at those companies are plausible
• Adjacent industries you should consider
• Executives who are not obvious but might be unusually good
• Geographic considerations
• Compensation expectations
• Which candidates are likely to be receptive
• Where the talent pool is thin
• What tradeoffs you'll have to make

For a truly senior hire, the quality of the market thesis is often more important than the size of the firm's database.

4. Give them a deliberately difficult search specification

Don't just give them a job description.

Tell them what you actually need the executive to accomplish in the first 24–36 months.

For example:

"We need someone who can take a $500M business from X to Y, professionalize the leadership team, and prepare it for an eventual transaction. They need enough operating experience to make hard decisions themselves, but enough board sophistication to manage sophisticated investors."

Then ask each firm:

"What would your ideal candidate profile be?"

You'll learn a huge amount from their answers.

The best firms will challenge your assumptions rather than simply repeat your requirements back to you.

5. Check references—especially client references

Ask each firm for three references involving the partner you're considering, ideally:

1. A successful search very similar to yours
2. A difficult search that took longer than expected
3. A client who has used that partner more than once

And ask the references:

• Did they give you bad news quickly?
• Did they challenge the hiring committee?
• Were candidates genuinely differentiated?
• Did the partner stay involved?
• How good was the assessment?
• Did they understand the business, or just the job description?
• Did they manage candidate expectations well?
• Were there surprises about fees or process?
• Would you hire this exact partner again?

That last question is extremely revealing.

6. Understand what "retained" actually means

For a genuinely senior search, retained search is generally the model I'd expect. You're paying for an exclusive, research-intensive search, rather than paying only if someone gets hired.

Don't focus excessively on getting the lowest fee. Instead negotiate:

• Fee basis
• Payment milestones
• Replacement guarantee
• Exclusivity
• Search timeline
• What happens if the profile changes substantially
• What happens if the firm doesn't produce an acceptable slate
• Whether references/background assessment are included
• Candidate assessment methodology
• Expenses
• Who owns the candidate relationship

The economics matter, but a mediocre search that costs 20% less is an extraordinarily expensive bargain if you hire the wrong executive.

7. I'd use a simple scorecard

I'd score each finalist from 1–5 on:

And I'd make one rule:

No firm advances because of its brand.

If the Spencer Stuart partner is mediocre but the SPMB partner has personally placed five people exactly like the person you need, I'd take the latter very seriously.

One thing I'd do before contacting anyone

Create a one-page search brief containing:

• Company situation
• Why the role exists
• What success looks like in 12/24/36 months
• 5–7 must-have characteristics
• 3–5 desirable characteristics
• Likely compensation range
• Reporting relationship
• Board/investor context
• Geography
• Companies/executives you already regard as interesting
• Things that would make someone look qualified but actually disqualify them

Then send the same brief to 4–5 firms. That makes their pitches much easier to compare.

If you tell me the role (e.g., CEO/CFO/COO/Chief Product Officer), industry, company size/stage, geography, and what makes the search unusually difficult, I can narrow this to 3–5 specific firms/partners I'd interview and explain why, including Bay Area boutiques versus the big global firms.
