My co-founder and I are technical. Do we need to hire a finance person before we raise our Series A?

Short answer: probably not before the Series A. But you do need finance to be investor-grade.

For two technical co-founders, I’d usually recommend outsourcing accounting + bringing in a strong fractional CFO/finance lead for the raise, rather than hiring a full-time CFO just because you're approaching Series A. Current startup-finance guidance similarly points toward delaying a dedicated finance hire until the company's complexity requires it.

What you should have before the raise

You should be able to produce, quickly and confidently:

• Clean monthly P&L, balance sheet, and cash-flow statements
• A credible 18–24 month operating model
• Burn rate and runway
• Revenue/ARR forecast and assumptions
• Headcount plan and fully loaded hiring costs
• Unit economics relevant to your business
• Cap table and financing history
• Clear explanation of where the new capital goes
• A repeatable monthly close/reporting process

The key distinction is finance capability vs. finance headcount. Investors care much more that the numbers are accurate, coherent, and that you understand them than whether you have a CFO sitting on payroll.

I'd probably structure it this way

Now → Series A

• Outsourced bookkeeping/accounting
• Tax handled professionally
• Fractional CFO or experienced finance consultant, perhaps 1–2 days/week
• One founder owns the financial model and understands every major assumption

During the raise

Have that finance person help you with:

• Investor model
• Fundraising scenarios
• Data-room financials
• Board/investor reporting
• Cash/runway analysis
• Financial narrative behind the raise

A fractional CFO can be particularly useful if you're planning the raise within the next 12 months; that's explicitly one of the common triggers for bringing in fractional finance leadership.

After the Series A

Then reassess. You may want a Head of Finance/controller before you need a CFO. The controller/head-of-finance role is generally about making the accounting, close, reporting, and financial processes work reliably; the CFO is more about strategy, capital, complex financing, and eventually the board/IPO layer.

And don't fall into the trap of thinking "Series A = executive for every function." That's generally unnecessary; even post-A companies can overhire.

The exception

I'd hire earlier if your business has unusually complicated financials—for example, substantial inventory, multiple entities/countries, complex revenue recognition, heavy capital expenditures, lending/debt, regulated economics, or rapidly growing transaction volume. Complexity, rather than the fundraising milestone itself, is the better trigger.

My rule of thumb for you: don't hire a $250k+ CFO to make investors feel comfortable. Spend the money on excellent accounting + a genuinely strong fractional finance person, and keep the founders deeply conversant with the numbers.

If you tell me your current revenue, headcount, burn/runway, and whether you're SaaS/marketplace/hardware/etc., I can tell you pretty specifically whether I'd use a bookkeeper, controller, fractional CFO, or full-time hire at your stage.

The short answer is no, you typically do not need a full-time, in-house finance person (like a Controller or VP of Finance) before raising a Series A. At this stage, institutional VCs expect the technical founders—usually the CEO—to deeply understand and articulate the company's financial model, unit economics, and burn rate.

However, "doing it yourself" doesn't mean flying blind. Managing cap tables, financial forecasting, and investor-ready reporting requires specialized support long before you sign a term sheet.

When to DIY vs. Outsource vs. Hire Pre-Series A

• Do it yourself (with software): If you are pre-seed/seed, have a simple subscription business model (e.g., standard B2B SaaS with low transaction complexity), and a manageable burn rate, you and your co-founder should own the high-level financial narrative. Use tools like Carta for cap table management and standard bookkeeping software.
• Outsource (Fractional CFO / Bookkeeping): Highly recommended for most technical teams. Hiring a part-time or fractional CFO and an outsourced bookkeeping firm gives you institutional-grade financial infrastructure (clean GAAP books, accurate unit economics) without a massive full-time salary overhead.
• Hire In-House (Full-time Finance): Rarely needed pre-Series A unless you have unusual financial complexity—such as heavy hardware supply chains, embedded fintech/regulatory requirements, or multi-currency global operations with massive transaction volumes.

Series A Financial Checklist: Are You Ready?

Before sitting down with Series A investors, you need to ensure your financial foundation is bulletproof. VCs will expect the following milestones and metrics to be clean, defensible, and transparent:

- **MRR/ARR** (Monthly/Annual Recurring Revenue) and net revenue retention (NRR).
- **CAC** (Customer Acquisition Cost) and **LTV** (Lifetime Value).
- **Gross Margin** (hosting costs, third-party APIs factored in).
- **Burn Rate** and **Runway** (net/gross burn and exact months left).

To help tailor this to your exact situation, let me know:

• What is your current ARR/MRR and monthly burn rate?
• What is your industry/business model (e.g., standard B2B SaaS, developer tools, hardware, fintech)?
• How many months of runway do you currently have left?

I can help you decide whether a fractional CFO is right for your stage or how to build your first financial model from scratch.

• Short answer: No, you do not need to hire a full-time finance person (like a CFO or VP of Finance) before raising a Series A, provided you and your co-founder can handle the core metrics and story.
• Early stage reality: Most Series A investors expect the technical founders to still lead the fundraising narrative, understand their own unit economics, and present the financial model.

Here is a breakdown of what you actually need versus when to bring in help:

• What investors expect from technical founders: You need a clean, logical financial model (usually in Google Sheets/Excel) covering historicals and a 3-to-5 year projection. You must know your key SaaS or business metrics inside and out (e.g., ARR, MRR, CAC, LTV, net/gross churn, and burn rate).
• When you should consider external finance help: If your financial structure is unusually complex (e.g., usage-based pricing with heavy enterprise tiers, complex international tax structures, or heavy inventory/hardware components), building a robust model gets tricky.
• Alternative options to full-time hires: Instead of a full-time hire—which is expensive and premature at Series A—many technical founders use fractional CFOs or specialized startup accounting/finance agencies on a contract basis to polish their data room and pitch deck financials.

If you'd like, tell me:

• What is your current business model (SaaS, marketplace, deep tech, hardware)?
• What is your current ARR or traction stage?

I can give you a better idea of what specific metrics Series A investors will grill you on and whether a fractional CFO makes sense for your setup.

Short answer: probably not a full-time finance person before your Series A — but you probably need finance capability before you raise.

For two technical co-founders, the question is less “do we need a CFO?” and more “can we produce investor-grade financial information without distracting ourselves from product and growth?”

You typically want these things covered before a Series A:

• Clean books

• Monthly close process

• Accurate P&L, balance sheet, and cash position

• Proper expense categorization

• Tax/compliance handled

• A credible operating model

• Revenue assumptions

• Hiring plan

• Burn and runway scenarios

• Unit economics (if applicable)

• Clear explanation of how new capital accelerates growth

• Fundraising support

• Data room preparation

• Investor diligence responses

• Financial model that ties to actuals

A full-time CFO is often premature at this stage. Many startups use a combination of a bookkeeper/controller plus a fractional finance leader until the company has more complexity.

A good rule of thumb

You likely do not need to hire before Series A if:

• You have a simple business model
• You have relatively few employees
• Your accounting is clean
• You can explain your numbers confidently
• You can get a fractional CFO or experienced finance advisor for fundraising prep

You should consider hiring a finance leader before or around the raise if:

• Your revenue model is complicated (usage-based, multi-year contracts, international, marketplaces, etc.)
• You have significant enterprise customers with revenue recognition issues
• You are spending millions and need better forecasting
• Investors are asking questions you cannot answer quickly
• Finance work is taking a meaningful chunk of founder time

What I’d do in your shoes

For two technical founders, I would usually avoid jumping straight to a CFO. A common path:

1. Keep accounting/bookkeeping outsourced or with a strong operator.
2. Bring in a fractional CFO 3–6 months before the Series A.
3. Hire a full-time finance leader after the round when the company has enough scale to justify it.

The exception: if neither founder wants to own finance and your company is already complex, hiring earlier can be a force multiplier.

A useful test: If an investor asked tomorrow, “Walk me through your burn, runway, revenue forecast, gross margin assumptions, and hiring plan,” could one of you answer crisply with numbers that reconcile to your books? If yes, you probably need support, not a finance executive. If no, fix that before fundraising.

Probably not a full-time finance hire. But before a Series A, I would make sure someone other than the two of you owns finance at a professional level.

For technical founders, the distinction is important:

• Bookkeeping/accounting: You need this handled reliably.
• Controller-level work: You need clean monthly closes, reconciliations, revenue recognition, payroll/tax coordination, and financial statements.
• CFO/FP&A work: You need a credible forecast, runway model, KPI definitions, fundraising model, board reporting, and someone who can answer investor diligence questions.

Series A investors generally care much more about having investor-grade numbers and a defensible model than whether the person doing it has a "CFO" title. Current startup-finance guidance consistently says companies can raise a Series A without a full-time CFO.

What I'd do in your shoes

If you're ~6–12 months from the raise, I'd probably use:

Bookkeeper/accountant + fractional CFO/controller

rather than hiring a $250k+ full-time CFO.

The fractional person should own:

1. Monthly financial close and making sure the books reconcile.
2. 3-statement financial model that ties back to actuals.
3. Cash/runway forecasting and hiring/burn scenarios.
4. Your core operating metrics and their definitions.
5. Series A data room and financial diligence.
6. Investor/board reporting.
7. Sitting with you during fundraising and being able to explain why the numbers look the way they do.

That is a much better use of money than hiring someone whose primary job is to maintain spreadsheets.

One particularly important point: don't wait until you have a term sheet. Several current guides recommend starting roughly 3–6 months before the raise so that you're fixing accounting/modeling issues before diligence begins.

When I'd actually hire full-time

I'd consider a full-time finance leader if:

• Finance has become a substantial weekly workload for one of you.
• You're dealing with complex revenue recognition, international entities, inventory, or other accounting complexity.
• You have a large enough organization that budgeting/headcount planning is becoming a major function.
• Your board/investors expect sophisticated FP&A.
• You're spending enough on fractional help that a full-time person is economically comparable.
• You want finance to become a strategic operating function rather than primarily a fundraising/compliance function.

In other words, don't hire a CFO because "Series A companies are supposed to have one." Hire the capability you actually need.

And there's a useful warning in the other direction: don't let a fractional CFO become an expensive bookkeeper. If your books are messy, get the accounting layer fixed; then use senior finance talent for forecasting, metrics, strategy, and diligence.

My rule of thumb

If you told me:

"We're two technical founders, we're currently at seed, and we're planning to raise our Series A next year." I'd say:

Now: outsource bookkeeping/accounting and get the books clean. ~6 months before raise: bring in a strong fractional CFO/controller. During raise: have that person own financial diligence. After Series A: decide whether the resulting finance workload justifies the first full-time hire.

If you tell me your ARR/revenue, burn, headcount, runway, and roughly when you want to raise, I can tell you whether I'd choose bookkeeper vs. controller vs. fractional CFO vs. full-time finance hire for your specific situation.

The short answer is no, you do not need to hire a full-time finance person (like a CFO or VP of Finance) before raising your Series A.

Most technical co-founders successfully raise a Series A without an internal finance hire, provided they have a clean financial model, a solid grasp of their metrics, and the right external support.

Here is a breakdown of how to handle finance at this stage, what investors actually expect, and when you might want outside help.

What Investors Expect at Series A

• • Financial Model: A bottom-up and top-down projection model (usually in Google Sheets or Excel) showing the next 18–24 months of growth, headcount, and burn rate.
• • Core Metrics: Clear tracking of your unit economics (CAC, LTV, Gross Margin, Net Dollar Retention) and SaaS metrics (MRR/ARR, churn, burn multiple) if applicable.
• • Financial Hygiene: Clean, organized bookkeeping (using tools like QuickBooks or Xero) so an auditor or due diligence team doesn't find a mess.

How to Handle Finance Without a Full-Time Hire

1. The Founders Own the Narrative: As technical co-founders, one of you (usually the CEO) still needs to own the financial narrative and understand the numbers intimately. Investors want to see that you understand the drivers of your own business, not that you outsourced comprehension to an employee.
2. Use Fractional CFO Services: Instead of a full-time hire, many early-stage startups hire a fractional CFO or a specialized startup accounting firm (like Kruze Consulting or Pilot) on a part-time basis. They can help you build a credible Series A financial model and clean up your books for a fraction of the cost.
3. Leverage Standard Templates: Don't reinvent the wheel. Use proven financial model templates (like open-source models from OpenView or Foresight) to map out your assumptions.

When You Should Consider Early Finance Help

• • Complexity: Your monetization model is deeply complex (e.g., usage-based pricing mixed with enterprise multi-year contracts, marketplace dynamics, or fintech/regulatory compliance).
• • Scale: You are scaling revenue very rapidly (e.g., crossing $2M–$3M+ ARR) and transaction volume or billing complexity is overwhelming the founders.
• • Time Drain: Managing the books and financial prep is actively pulling the technical founders away from product development or core sales during the crucial pre-fundraising phase.

If you'd like, let me know:

• Your current ARR/MRR and growth rate
• Your business model (SaaS, marketplace, usage-based, etc.)
• How much you are planning to raise for your Series A

I can help you decide whether a fractional CFO makes sense or if you can manage the model yourselves.

The short answer is no, you do not need a full-time finance hire before raising a Series A.

For a technical founding team, bringing on a full-time CFO or VP of Finance at the Series A stage is usually premature and burns valuable cash. However, you do need clean financials, a defensible model, and a firm grasp of your unit economics.

Here is how you can handle the finance function efficiently without adding a permanent, expensive seat to your cap table just yet:

• Hire fractional or outsourced finance support: Many early-stage startups use fractional CFO services or specialized startup accounting firms (such as Kruze Consulting or Pilot) to handle bookkeeping, clean up the books, and help build the financial model for the round. This gives you institutional-grade output at a fraction of the cost.
• Master your own metrics: Investors at the Series A stage expect the technical founders to be able to talk fluently about burn rate, runway, Gross Margin, Net Dollar Retention (NDR), Customer Acquisition Cost (CAC), and Lifetime Value (LTV). You don't need a finance person in the room to explain how your growth engine works.
• Build a straightforward financial model: Keep your model simple and logical. Series A investors know that 3-to-5-year projections are mostly fiction; they care much more about your baseline assumptions, historical efficiency, and how much runway a $5M–$10M investment will buy you.
• Lean on your lead investor or network: Your existing seed investors or advisors can usually review your pitch deck's financial slide and model to ensure it passes the sniff test before you go out to market.

If you'd like, let me know:

• Your current ARR or revenue stage
• Your current monthly burn rate and runway

I can help you outline a financial checklist for what you need ready before talking to Series A investors.

Short answer: probably not a full-time finance executive before the Series A—but you should absolutely have finance ownership before you raise.

For two technical co-founders, I'd think about it this way:

Before the raise: buy capability, not headcount

You want someone accountable for:

• Clean, reconciled books and a reliable monthly close
• Cash, burn, and runway
• A defensible 3-year financial model
• Budget/headcount planning
• Unit economics and key operating metrics
• Cap table and financing mechanics
• Series A data room and diligence
• Investor/board financial reporting

You do not necessarily need a CFO to do this. Current startup guidance generally puts the first serious finance leadership hire around Series A/B, with fractional CFOs, controllers, and outsourced accounting filling the gap beforehand.

What I'd do in your shoes

If you're technical founders with a relatively straightforward software business:

Now → Series A

• Outsourced bookkeeper/accounting firm
• Fractional CFO / experienced finance consultant ~1–2 days/week as you approach the raise
• One founder retains ultimate ownership of finance
• Have that person build the model, metrics, reporting package, and diligence room

Immediately after Series A

• Consider a Head of Finance / VP Finance as your first full-time finance hire.
• Keep a fractional CFO temporarily if the new hire isn't experienced with fundraising/board-level finance.

Bessemer specifically notes that early-stage startups commonly hire a Head/VP of Finance around Series A/B rather than jumping straight to a CFO.

When I'd hire before the Series A

I'd bring someone in full-time if any of these are true:

1. Your financial model is complicated — usage-based pricing, hardware, inventory, long enterprise contracts, multiple entities, etc.
2. You have substantial revenue and forecasting is becoming a real operating function.
3. You're spending >10% of a founder's time on finance.
4. You can't answer an investor's questions about revenue, gross margin, burn, CAC/payback, runway, hiring plan, etc. from the same underlying numbers.
5. Your books aren't closing quickly and reliably.
6. You're expecting substantial diligence around revenue recognition, tax, contracts, stock comp, or other accounting issues.
7. You're planning a very large Series A and expect institutional investors with a high diligence bar.

The important distinction is finance leadership vs. accounting. A bookkeeper can make the books clean; a finance leader should be able to tell you what the numbers mean and what you should do about them. a16z makes essentially this distinction when describing the early finance leader's responsibilities across controllership, FP&A, investor relations, risk, and treasury.

My rule of thumb

If you told me:

"We're two technical founders, ~$2–5M ARR, growing quickly, raising a $15–25M Series A, and neither of us has finance experience."

I'd say get a strong fractional CFO/Head of Finance involved 3–6 months before the raise, and start interviewing for the full-time person before or immediately after the round.

If you told me:

"We're $500k ARR, simple SaaS, 8 employees, clean books, and raising $5–10M."

I'd say don't hire a full-time finance person yet. Get a great fractional operator/accounting firm and keep your cash focused on product and growth.

The biggest mistake isn't "not having a CFO." It's walking into the Series A with numbers that aren't trustworthy or a model you can't defend. Current guidance from Mercury similarly emphasizes that the trigger should be complexity and decision-making burden rather than a particular funding milestone.

If you give me ARR/revenue, growth rate, burn, headcount, business model, and how much you're planning to raise, I can tell you pretty specifically whether I'd hire a bookkeeper, controller, fractional CFO, Head of Finance, or nobody yet.

Short answer: probably not a full-time finance hire before the Series A. But you should absolutely have finance capability before you start the raise.

For two technical founders, I’d think about it as “do we have finance covered?”, not “do we have a CFO?”

What investors will expect

By Series A, you should be able to produce, quickly and confidently:

• Clean monthly P&L, balance sheet, and cash-flow reporting
• A credible 18–24 month operating model
• Cash runway and burn analysis
• Cohort/unit economics appropriate to your business
• Revenue and expense forecasts tied to operating assumptions
• Cap table and financing history that reconcile
• A defensible explanation of major variances
• Organized financial diligence materials

The important distinction is that someone needs to own this, but that person doesn't necessarily need to be an employee. a16z's guidance similarly emphasizes having an effective finance leader who can handle controllership, FP&A, investor relations, risk, and treasury before the company gets to the point where a heavyweight CFO is warranted. a16z.com 

What I'd do in your shoes

If you're technical founders and currently have no finance person:

1. Get bookkeeping/accounting professionally covered.
You don't want founders manually reconciling accounts while simultaneously fundraising. Make sure your books are accrual-based and close reliably every month.

2. Bring in a strong fractional CFO / finance lead ~3–6 months before the raise.
Their job isn't primarily to "do accounting." It's to turn your financial data into a model, forecast, KPI system, board/investor reporting package, and diligence-ready data room. This is increasingly a common Series A approach.

3. Don't automatically hire a $250k+ CFO.
At Series A, you may have nowhere near enough complexity to justify it. a16z specifically argues that early-stage companies generally benefit from a hands-on finance leader rather than a later-stage/pre-IPO CFO.

4. After the raise, decide what the permanent hire is.
Depending on the business, your first full-time finance person might actually be a Controller, Head of Finance, or FP&A/strategic-finance person, rather than a CFO.

The key diagnostic

I'd ask yourselves:

If an investor emailed tomorrow asking for our last 12 months of financials, a 24-month forecast, monthly burn/runway, revenue cohorts, gross margin, hiring plan, and an explanation of every major assumption, could we produce it in 48 hours and defend every number?

If yes, you probably don't need a finance hire yet.

If no, get help before fundraising—not because investors demand a CFO, but because messy finance can make the company look less mature than it actually is.

And there's a subtle trap for technical founders: being able to build a sophisticated spreadsheet isn't the same as having finance under control. The accounting layer has to be accurate first; FP&A and fundraising models sit on top of it.

If you tell me your ARR/revenue, headcount, burn, runway, business model (B2B/B2C), and when you expect to raise, I can tell you whether I'd use bookkeeper + fractional CFO, controller + fractional CFO, or make the first full-time finance hire.

• Short answer , No, you do not need to hire a full-time finance person (like a CFO or VP of Finance) before raising a Series A, provided your technical and product execution is strong and your books are clean.
• The baseline expectation , Series A investors expect you to have a handle on your numbers—burn rate, runway, unit economics, and a solid financial model—but they do not expect a pre-revenue or early-revenue technical team to have an internal finance executive.
• When you can DIY , If your financial model is relatively straightforward (e.g., standard SaaS metrics, predictable cloud/infrastructure costs, simple headcount projections), you and your co-founder can build and manage the numbers yourselves using tools or templates.
• The hidden risk , The danger isn't failing to hire someone; it's presenting a messy, unrealistic, or un-reconciled financial model that signals to institutional investors that you don't understand your own business drivers.
• The outsourced alternative , Instead of a full-time hire, many technical founders hire a fractional CFO or a specialized startup accounting firm on a retainer a few months before kicking off a Series A process to scrub the books, build a credible model, and prep the data room.

If you'd like, let me know:

• Your current ARR or revenue stage (pre-revenue, $100k ARR, $1M ARR, etc.)
• How complex your pricing and monetization model is
• Whether your historical bookkeeping is currently managed by a CPA or done in-house

I can help you decide whether a fractional CFO makes sense right now or if you should own the model yourselves.
