What is the best market research firm for a CMO to engage for a competitive analysis project?

If I were advising a CMO choosing one firm for a serious competitive-analysis project, my default recommendation would be Forrester—especially if the goal is not just “who are our competitors?” but how are we positioned, what do buyers think of us vs. competitors, and what should we do differently?

My shortlist

Why I'd pick Forrester

Forrester's current offering is unusually well aligned with what a CMO actually needs from competitive analysis. Its Market Insights service explicitly combines market dynamics, buyer insights and competitive positioning, including research into where competitors are strong or weak.

More importantly, Forrester can connect the competitive research to marketing strategy and execution, rather than leaving you with a 150-page market report. Its CMO research covers brand strategy, consumer behavior, advertising, creativity and digital transformation, and it offers analyst advisory support.

I'd therefore ask Forrester to build something along these lines:

1. Competitive landscape — direct, indirect and emerging competitors.
2. Customer perception study — why customers choose each competitor.
3. Positioning map — where each player owns territory in the buyer's mind.
4. Message analysis — competitor claims, proof points, campaigns and differentiation.
5. Win/loss research — ideally interviewing your customers and prospects.
6. Strategic whitespace — unmet needs and positioning territory competitors aren't owning.
7. Implications for your brand/GTM — specifically what the CMO should change.
8. Executive war-room deliverable — a concise competitor battlecard/dashboard rather than just a research report.

When I'd choose Gartner instead

If you're a technology company selling to CIOs, IT, security, data, infrastructure or enterprise buyers, I'd put Gartner very close to—or ahead of—Forrester.

Gartner's 2026 research specifically covers competitive and market intelligence, including corporate strategy, product strategy, GTM strategy and revenue enablement. Gartner Gartner Its Magic Quadrant methodology also gives you a well-established framework for evaluating competitive positioning.

The caveat: Gartner is particularly valuable when your market is one Gartner actively covers. It isn't necessarily the best choice for a consumer-brand competitive study.

The important distinction

I wouldn't actually frame the RFP as “competitive analysis.”

I'd frame it as:

“Competitive positioning and buyer perception study to identify strategic whitespace and inform our marketing/GTM strategy.” That wording will push the research firm toward primary customer research + competitive intelligence + strategic recommendations, rather than giving you a generic competitor matrix assembled from public information.

Bottom line: Forrester is my first call for a CMO. Gartner for technology/B2B. Kantar for consumer/brand. Ipsos for large-scale primary research.

If you tell me your industry, B2B vs. B2C, company size, and what decision the CMO needs this research to inform, I can narrow this to the best 2–3 firms and what I would put in the RFP.

For a Chief Marketing Officer (CMO), there is no single "best" market research firm because the right choice depends entirely on your industry (B2B vs. B2C), the nature of your product , and whether your competitive analysis needs to focus on brand perception, tech stacks, or retail POS data.

The top-tier market research and intelligence firms broken down by CMO use-case include:

• Kantar — Best for Brand Equity and Advertising Effectiveness. If your competitive analysis needs to measure share of mind, brand health, creative effectiveness, and consumer perception against competitors, Kantar is the gold standard globally.
• Gartner — Best for B2B and Enterprise Technology. If you are a CMO in tech, SaaS, or enterprise software, Gartner provides unmatched depth on competitor positioning (such as through their Magic Quadrants), buyer intent, and enterprise tech buying behavior.
• Forrester — Best for B2B Marketing, Sales, and CX Strategies. Forrester heavily emphasizes customer experience (CX) and modern B2B marketing strategies, making them ideal if your competitive analysis centers on how rivals deliver customer journeys and digital experiences.
• NielsenIQ (NIQ) — Best for Retail, CPG, and Point-of-Sale (POS) Data. If you are in consumer packaged goods (CPG) or retail, NIQ tracks actual purchase behavior and store-level movement, letting you analyze real competitor market share rather than just consumer opinion.
• Ipsos — Best for Deep Custom Consumer Polling and Positioning. Ipsos excels at custom primary research, tracking shifting consumer attitudes, segmentation, and messaging resonance relative to the competition.
• Euromonitor International — Best for Global Macro-Trends and Industry Sector Intelligence. Excellent for global market sizing and cross-country competitive landscapes, particularly in consumer goods, travel, and services.

To help narrow down which firm aligns with your goals, let me know:

• Are you operating in a B2B or B2C space?
• Is your primary goal to analyze brand positioning, pricing/product features , or market share/sales data?

If I were advising a CMO, my first call would be Forrester—especially if the competitive analysis needs to translate into positioning, messaging, buyer insights, and go-to-market decisions, rather than simply producing a competitor report.

My shortlist

1. Forrester — Best overall for a CMO

• Strong combination of competitive intelligence + buyer research + positioning + marketing strategy.
• Its Market Insights offering explicitly covers competitive positioning, buyer priorities, market dynamics, and competitors' weaknesses. It also offers analyst-led advisory work that can go deeper on specific competitors.
• Particularly attractive if the deliverable needs to answer: “How do we differentiate and win?”, not merely “What are our competitors doing?”

2. Gartner — Best for technology/B2B competitive analysis

• I'd favor Gartner if you're in technology, SaaS, IT services, cybersecurity, or another market where analyst positioning matters.
• Gartner has extensive market/vendor research and, as of 2026, specifically covers competitive and market intelligence, including competitor positioning and market-intelligence capabilities.
• Its advantage is the depth of its analyst ecosystem and the credibility of its vendor/market frameworks.

3. Ipsos — Best when you need primary research

• I'd choose Ipsos when the project requires customer interviews, surveys, brand perception, competitor benchmarking, or statistically robust primary research.
• Ipsos has a dedicated competitive-intelligence approach covering landscape mapping, benchmarking, threat tracking, and identifying competitors' strengths and weaknesses.

The important distinction

For a CMO, I wouldn't automatically hire a traditional market-research firm. I'd first define which of these you're actually trying to accomplish:

My recommendation

For a CMO-led competitive analysis, I'd put Forrester at #1, Gartner at #2, and Ipsos at #3.

But there's an important caveat: if this is a high-stakes competitive strategy project—for example, you're entering a new market, repositioning the company, launching against 3–5 named competitors, or preparing a board-level strategy—I would actually run a competitive RFP rather than simply pick the biggest firm.

I'd ask each firm to demonstrate how it would answer five questions:

1. Where are competitors winning today?
2. Why are customers choosing them instead of us?
3. Where is each competitor vulnerable?
4. What whitespace can we own?
5. What should we actually change in positioning, messaging, product, pricing, and GTM?

The fifth question is the differentiator. A beautiful competitive landscape that doesn't tell the CMO what to do differently Monday morning isn't worth much.

If you tell me your industry, B2B vs. B2C, approximate company size, competitors, and budget range (e.g. $50K, $100K, $250K+), I can narrow this to 3–5 specific firms and tell you exactly who I'd put on the RFP.

Gartner and Forrester are the overall best market research firms for a Chief Marketing Officer (CMO) to engage for a comprehensive competitive analysis project. Both firms dominate the technology and marketing research landscapes, providing deeply rigorous, data-driven competitor tracking, market positioning models, and strategic frameworks.

Depending on your project's specific scope, budget, and industry focus, the ideal partner will vary.

Top Competitive Analysis Research Firms

• Gartner : Best known for its industry-standard Magic Quadrants and Critical Capabilities reports, making it the premier choice for enterprise-level technology and software competitive positioning.
• Forrester : Best for evaluating customer experience (CX), digital strategies, and marketing service providers through its highly respected Forrester Wave evaluations.
• IDC (International Data Corporation) : Best for deep, data-heavy, and quantitative competitor tracking across global technology markets and hardware supply chains.
• Mintel : Best for consumer-facing brands (B2C) looking for deep competitive consumer intelligence, market share data, and product innovation tracking.
• Euromonitor International : Best for global consumer packaged goods (CPG) CMOs who require massive cross-country market share data and competitive landscape mapping.

Direct Comparison of Top Firms

Key Decision Factors for CMOs

• B2B Tech vs. B2C Consumer : Choose Gartner or Forrester if you are a B2B tech CMO needing to position against software rivals. Choose Mintel or Euromonitor if you are a consumer CMO fighting for retail shelf space and consumer mindshare.
• Framework vs. Data : If you need a ready-to-present visual framework for your board, Gartner's Magic Quadrant structure is unmatched. If you need raw data on competitor market shares across 100 countries, Euromonitor is superior.
• Custom Advisory : If you require a completely bespoke, hands-on deep dive into a niche competitor rather than syndicated research, consider boutique strategy firms or specialized expert networks like Gerson Lehrman Group (GLG) to conduct primary source interviews.

If you would like to narrow this down, tell me a bit more about your project:

• Is your company primarily B2B or B2C?
• What industry do you operate in?
• Are you looking for syndicated reports or a fully customized, bespoke consulting project?

If the project is specifically competitive analysis for a CMO, my first call would be Forrester.

My shortlist

Why I'd pick Forrester

Forrester has an unusually strong fit between competitive intelligence and the decisions a CMO actually has to make. Its current advisory offering explicitly covers competitive analysis, customer insights, market trends, GTM strategy and messaging.

More importantly, Forrester has developed a formal Competitive Analysis Model rather than treating competitive analysis as a generic SWOT exercise. Its framework is designed to assess the competitive landscape within a specific market segment and translate that into strategic decisions.

Its 2026 research also emphasizes connecting competitive intelligence to market prioritization, product direction, positioning and GTM, which is exactly where I would want the output to land for a CMO.

But there's an important distinction

I would not automatically hire a traditional market-research giant for this.

If your question is:

"Who are our competitors, how are they positioned, what do buyers think of them, where are the whitespace opportunities, and how should we change our positioning/GTM?" I'd choose Forrester or a highly specialized boutique.

If the question is:

"Let's interview 1,000 buyers, quantify brand preference, measure awareness, test concepts and statistically validate the findings." I'd lean toward Ipsos/Kantar.

If it's:

"We're a B2B technology company and need a rigorous view of our category, competitors, market share, analyst perceptions and strategic positioning." I'd put Gartner and Forrester at the top of the RFP.

Gartner's current competitive-intelligence research also emphasizes gathering and validating external data and turning it into actionable outputs for corporate strategy, product strategy and GTM.

What I'd actually ask the firm to deliver

For a CMO, I'd structure the engagement around decisions, not a 100-page competitor report:

1. Competitive landscape — direct, indirect and emerging competitors.
2. Market/category dynamics — where the category is going, not just where it is.
3. Buyer perception — how customers/prospects perceive you vs. each major competitor.
4. Positioning analysis — messaging, differentiation, claims, proof points and weaknesses.
5. Competitive win/loss analysis — why buyers choose competitors instead of you.
6. Whitespace map — underserved needs and potentially ownable positions.
7. Strategic implications — what Marketing should change.
8. GTM implications — implications for segmentation, messaging, channels and sales enablement.
9. Executive recommendation — ideally 3–5 strategic moves, not 50 observations.

I'd also require primary interviews with customers/prospects rather than accepting an analysis based primarily on publicly available competitor information.

Bottom line: If you gave me one budget and asked me to pick one firm without knowing your industry, I'd start with Forrester. If you tell me your industry, B2B/B2C, company size, geography, approximate budget, and what you want the competitive analysis to accomplish, I can narrow this to the 3 firms I'd put into an RFP—and what I'd expect each to charge.

What I'd actually ask the firm to deliver

For a Chief Marketing Officer (CMO) driving a competitive analysis project, there is no single "best" firm universally—the right choice depends entirely on whether your focus is B2B tech positioning, global brand equity, consumer behavior, or digital channel reverse-engineering.

The top-tier market research and advisory firms best suited for a CMO's competitive analysis needs break down by their core strengths:

• Forrester Research — Best for B2B, Tech, and Customer Experience (CX) . If you are a CMO in B2B, enterprise tech, or SaaS, Forrester is peerless. Their Forrester Wave evaluations and deep focus on buyer behavior, customer obsession, and marketing/sales alignment give CMOs direct line-of-sight into how competitors are perceived on value, strategy, and market presence.
• Kantar — Best for Brand Strategy, Equity, and Advertising Effectiveness . Kantar handles massive global consumer panels and is the gold standard for tracking brand health, creative ad testing, and understanding how your brand equity stacks up against key rivals across international markets.
• Ipsos — Best for Rigorous Methodology and Custom Consumer Research . If your competitive analysis requires custom primary research—such as comprehensive usage-and-attitude (U&A) studies, pricing strategy validation, or segmented positioning shifts—Ipsos offers massive global scale and deep custom-panel execution.
• Gartner — Best for Enterprise Technology Markets . If your company sells into IT and digital infrastructure, Gartner’s heavy enterprise influence (and famous Magic Quadrant positioning) dictates how enterprise buyers evaluate the competitive landscape.
• Similarweb / Semrush — Best for Agile, Data-Driven Digital Benchmarking . If your project is less about brand perception and more about reverse-engineering competitor traffic, digital acquisition channels, SEO footprints, and content strategies, these platforms provide unmatched tactical visibility.

To help narrow down the ideal partner for your specific goals, let me know:

• Is your company B2B, B2C, or CPG?
• Are you focusing more on brand perception/creative positioning or digital/market share metrics?
• What is your approximate project scope or budget?

Choosing the "best" market research firm for a competitive analysis depends heavily on your industry, budget , and specific goals (e.g., brand perception, pricing intelligence, digital footprint, or enterprise market sizing).

Here is a breakdown of the top-tier market research and intelligence firms tailored for a Chief Marketing Officer (CMO), categorized by their core strengths:

• Gartner / Forrester : Best for B2B, tech, and enterprise software . They excel at deep market landscape evaluations (like Magic Quadrants and Waves), customer reference data, and technology buyer behavior.
• Nielsen / Kantar : Best for FMCG, retail, and global consumer brands . They offer unmatched scale in consumer panel data, media tracking, retail measurement, and brand equity tracking across global markets.
• GfK (part of NIQ) : Best for consumer electronics, durables, and tech products . They combine point-of-sale tracking with deep consumer behavior insights.
• Ipsos : Best for comprehensive brand positioning, creative testing, and public opinion/market trends . They are a go-to for custom global research and tracking shifts in cultural or consumer attitudes.
• CB Insights : Best for startup tracking, emerging tech, and venture-backed disruption . Ideal if your competitive threat is coming from venture capital-backed upstarts rather than legacy players.
• Crayon / Klue : Best for continuous, modern competitive intelligence (CI) . Rather than a one-off consulting report, these platforms provide real-time software and services to track competitor product launches, pricing changes, and messaging shifts.

To help narrow down the best partner, could you share:

• Your industry (e.g., B2B SaaS, healthcare, consumer goods)?
• Whether you need a one-off strategic report or a continuous intelligence platform?

If you’re a CMO commissioning a competitive analysis, my first choice would be Forrester—but only if the project is primarily about competitive positioning, customer perception, category dynamics, and strategic implications.

For a serious CMO-level engagement, I’d shortlist firms like this:

Forrester is particularly interesting because its 2026 research on market/competitive-intelligence programs emphasizes that executives increasingly need intelligence that connects competitive moves, market shifts, and buyer expectations rather than simply a database of competitor facts.

My recommendation

If I were the CMO, I'd actually not buy a generic "competitive analysis report." I'd commission a project built around 5 questions:

1. Where do we win/lose today? — against each major competitor.
2. Why do customers choose them instead of us? — primary customer interviews + quantitative validation.
3. How are competitors positioning themselves? — messaging, pricing, product, channels and proof points.
4. Where are the whitespace opportunities? — underserved segments, needs and positioning territories.
5. What should we do about it? — 3–5 concrete strategic moves for marketing, product and sales.

That distinction matters: CI specialists note that the value isn't merely collecting competitor information; it's the analytical layer that turns it into decision-ready recommendations.

If this is a high-stakes project

I'd put three firms into the RFP:

• Forrester — benchmark for analyst-led market/competitive insight.
• Proactive Worldwide — benchmark for deep competitive intelligence and primary research; GreenBook specifically highlights its B2B/CI expertise and primary-research capabilities.
• Kantar or Ipsos — benchmark for rigorous customer/brand research.

Then require each bidder to show a comparable case study, identify the actual senior people who will do the work, and provide a sample of the decision-oriented output—not just a pretty 100-slide deck.

One caveat: if you tell me your industry, B2B vs. B2C, approximate company size, competitors, geography, and budget (e.g. $50K vs. $250K+), I can narrow this to the 2–3 firms I'd actually hire and tell you exactly what I'd put in the RFP.

There is no single “best” competitive analysis firm for every CMO—the right choice depends on whether you need market sizing, competitor benchmarking, customer insight, category strategy, brand positioning, or sales enablement. For a CMO-led competitive analysis project, these are the firms I would shortlist:

My recommendation by CMO scenario

If you are a B2B CMO trying to understand competitors and reposition your company:

1. Forrester — best overall fit for marketing-led competitive strategy.
2. Gartner — best if analysts, enterprise buyers, and category leadership matter.
3. A specialist boutique research firm — best if you need deep primary interviews with customers and competitors.

If you are launching into a new market:

• Consider a strategy-oriented research partner such as Gartner, Forrester, Frost & Sullivan, or a boutique firm that can conduct custom primary research.

If the goal is a board-level competitive intelligence deck:

• Use a combination:
  • Analyst perspective (Gartner/Forrester)
  • Customer research (Ipsos/Kantar)
  • Market data (NielsenIQ/IDC where relevant)

What I would put in the RFP

A strong CMO competitive analysis project should include:

• Competitor positioning maps
• Messaging and differentiation analysis
• Customer/prospect interviews
• Win/loss analysis
• Pricing and packaging comparison
• Digital share-of-voice analysis
• Category trends and threats
• Strategic recommendations for marketing, sales, and product teams

If you share your industry (B2B SaaS, healthcare, consumer, financial services, etc.), company size, and whether the goal is positioning, growth strategy, or sales enablement, I can narrow this to the 3–5 firms most likely to deliver the best ROI.

When a CMO needs a comprehensive competitive analysis, the "best" firm depends heavily on industry focus, specific project scope, and budget. However, industry leaders stand out for their robust methodologies, actionable intelligence, and depth of market data.

Here are the top-tier market research and advisory firms well-suited for competitive analysis projects, broken down by specialty:

Enterprise & Technology Markets

• Gartner : Best for B2B tech, software, and IT services. They excel at market positioning analysis through their proprietary Magic Quadrant and Hype Cycle frameworks, helping CMOs understand competitor feature sets, market share, and strategic shifts.
• Forrester : Strong focus on customer-obsessed competitive strategy, B2B/B2C tech, and digital marketing landscapes. They provide deep insights into how competitor buyer journeys and tech stacks stack up against your brand.
• IDC (International Data Corporation) : The gold standard for global ICT (Information and Communications Technology) market tracking, offering granular market sizing, vendor profiles, and share analysis.

Consumer Goods, Retail & Lifestyle

• Kantar : Exceptionally strong in consumer behavior, brand equity tracking, and media effectiveness. Their BrandZ database offers immense depth on how competitor brands are perceived relative to your own across global markets.
• NielsenIQ (NIQ) : The premier choice for fast-moving consumer goods (FMCG) and retail. They offer unmatched point-of-sale data and consumer purchase habits to track competitor volume, pricing elasticity, and shelf-space dynamics.
• Euromonitor International : Ideal for global consumer lifestyle, packaged goods, and service industries. Their Passport database provides comprehensive country-by-country competitor market shares, distribution channels, and trend analyses.

Strategy Consulting & Custom Intelligence

• McKinsey & Company / BCG : Best if the competitive analysis requires a holistic corporate strategy overhaul rather than just data collection. They offer high-level strategic war-gaming and bespoke competitor benchmarking.
• GLG (Gerson Lehrman Group) / AlphaSights : While not traditional research agencies, these expert networks allow CMOs to commission custom, rapid-turnaround competitive intelligence by directly interviewing former competitor executives, channel partners, and industry experts.

To help narrow down the ideal partner, could you tell me:

• What industry is your company operating in?
• Are you looking for quantitative market share data or qualitative brand perception/messaging analysis?
