Companies Using CrazyEgg

With 10+ years in web crawling and technographic data analysis, I've examined CrazyEgg's position in the heatmap and website optimization space as part of our ongoing coverage of 40K+ technologies. This analysis is based on 18,822 enriched company profiles (a 55.1% match rate against 34,157 detected domains), cross-referenced with G2 review data, TrustRadius ratings (8.1/10 across 130 reviews, per trustradius.com), CrazyEgg's own published case studies, and revenue data from Latka ($4.5M in 2025, per getlatka.com/companies/crazyegg), as of our April 2026 crawl.

1. Growth trajectory

CrazyEgg's adoption curve tells a story of slow-burn growth followed by a late-stage acceleration. From its first detection in 2005, the platform took 15 years to reach 9,179 active domains in January 2020. Then came a dramatic shift: active installs surged from 9,179 to 30,593 by December 2024, a 3.3x increase in just five years. That acceleration coincided with a broader market shift toward conversion rate optimization as businesses moved online. CrazyEgg's own homepage claims over 449,000 websites trust the platform (per crazyegg.com/pricing), though our detection data captures currently active script installations.

The recent pullback to 25,479 active domains in mid-2025 aligns with the revenue decline Latka reported: $4.5M in 2025, down 28% year-over-year. Total domains (active + inactive) have been declining since 2018, while active domains grew through 2024, meaning CrazyEgg's customer base was consolidating around committed users. The 2025 reversal suggests that consolidation has reached its limits.

"CrazyEgg tripled its active install base in five years while total domains declined. That's not growth through acquisition, it's growth through retention. The companies that adopt CrazyEgg tend to keep it, at least until a free competitor makes them rethink the cost." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: The 2020-2024 growth spike offers a natural conversation starter. Sales teams can reference this adoption wave when approaching companies still evaluating heatmap tools. The revenue decline creates a price-sensitivity angle: companies considering CrazyEgg may be open to annual commitments in exchange for discounts.

2. Customer profile

52% of CrazyEgg customers have 1-10 employees. Add the 11-50 bracket and you get 72.4% with under 50 people. This is a tool built for small teams that need visual answers without a data science department. The dominant founding decade is the 2010s at 33.6%, followed by the 2000s at 19.85%, making the typical CrazyEgg customer a 7-15 year old small business that's outgrown basic analytics but can't justify enterprise pricing.

The enterprise tail is more interesting than the number suggests. 2.8% of customers have 10,001+ employees, including PwC, Johnson & Johnson, Salesforce, American Express, and General Electric. CrazyEgg's enterprise page (crazyegg.com/enterprise) details how TSheets by QuickBooks used CrazyEgg recordings and heatmaps to identify that 50% of pricing page visitors were scrolling back to the navigation instead of converting. WallMonkeys achieved a 550% conversion rate increase through A/B testing (source: crazyegg.com/case-study/wall-monkeys). Happy Trails, a family-owned off-road motorcycle retailer, saved $90,000+ in four months and cut 600+ developer hours by using session recordings to catch checkout bugs in real time (source: crazyegg.com/case-study/happy-trails). These aren't just logo detections; they're vendor-verified deployments with published outcomes.

Sales Signal: The 72.4% small-business concentration means CrazyEgg's install base is full of companies that buy tools quickly, with short sales cycles and credit-card-driven purchasing. For services companies targeting this segment, CrazyEgg's presence is a reliable signal that the prospect invests in web optimization.

3. Industry and geographic concentration

Retail leads at 5.81%, but the real story is how flat the distribution is: no single industry exceeds 6%. Software Development (4.16%), Medical Practices (4.05%), Real Estate (3.65%), and Advertising Services (3.31%) round out the top five. CrazyEgg is genuinely horizontal, unlike competitors such as Hotjar that skew toward SaaS and tech.

Geographically, the US accounts for 55.3% of all enriched companies, with the UK at 7.5% and Canada at 4.5%. English-speaking countries together make up over 71% of the user base. Spain (1.5%) and Mexico (1.3%) represent the largest non-English markets, a pattern likely tied to Neil Patel's personal brand recognition in Latin markets.

Sales Signal: The flat industry distribution means CrazyEgg's customer list is a broad prospecting pool. Filter by industry on TechnologyChecker.io to find vertical-specific leads: medical practices optimizing patient portals, real estate companies testing property listing layouts, or retail brands refining product pages.

4. Migration patterns

This is where CrazyEgg faces its toughest numbers. Against Hotjar, CrazyEgg gained 2,657 companies but lost 7,874, a 3:1 loss ratio. Against Microsoft Clarity, the ratio is worse: 1,702 gained versus 7,310 lost, a 4.3:1 loss ratio. Clarity's zero-cost model is pulling budget-conscious customers away at an accelerating pace, with 2,852 of those 7,310 losses happening in just the last year.

The one bright spot: CrazyEgg is net-positive against Mixpanel, gaining 1,315 and losing only 737. This makes sense. Mixpanel is a product analytics tool, not a heatmap competitor. Companies replacing Mixpanel with CrazyEgg are likely simplifying their stack rather than switching between similar tools.

"Microsoft Clarity's zero-cost model is reshaping the heatmap market. CrazyEgg's 4.3:1 loss ratio against Clarity signals that price-sensitive customers don't see enough differentiation to justify paying when a free alternative exists." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: Companies currently on CrazyEgg represent a retention risk for the platform but an opportunity for services providers. If a prospect recently dropped CrazyEgg for Clarity, they may need help configuring the free tool properly. Conversely, companies sticking with CrazyEgg despite free alternatives signal budget commitment to optimization.

5. Technology ecosystem

HubSpot is the dominant marketing tool at 11.21% overlap, more than double the next marketing automation platform (Klaviyo at 5.39%). This HubSpot-heavy stack suggests CrazyEgg's core users are conversion-focused marketers who treat heatmaps as one input in a broader funnel optimization workflow. Tawk.to (6.40%) and Intercom (3.75%) on the live chat side reinforce this: these companies care about visitor engagement at every touchpoint.

On the CMS side, Atlassian Cloud (7.17%) and Drupal (4.73%) rank above Squarespace and Wix, which skew toward the enterprise and government segments visible in the top companies list. The AngularJS (8.41%) and RequireJS (6.67%) frontend footprint points to legacy web applications, not modern React/Vue stacks.

Sales Signal: The HubSpot overlap is actionable. Companies running CrazyEgg + HubSpot are already investing in conversion optimization and marketing automation. They're likely open to consulting services, CRO agencies, or complementary tools that bridge the gap between behavioral data and marketing execution.

6. G2 review signals

G2 reviewers cite ease of use as the top positive (12 mentions), and TrustRadius gives CrazyEgg an 8.1/10 across 130 reviews (source: trustradius.com/products/crazyegg/reviews). The built-in A/B testing feature gets specific praise (4 mentions on G2), a differentiator since Hotjar requires a separate experimentation tool.

Sendible's marketing manager confirmed this in CrazyEgg's own case study: she switched from Hotjar to CrazyEgg specifically for the Confetti report's ability to segment clicks by new vs. returning visitors, calling it "the report that every marketer dreams of" (source: crazyegg.com/case-study/sendible). On the flip side, Conversion Rate Experts grew CrazyEgg's own homepage conversion rate by 363% and their checkout signups by 116% (source: conversion-rate-experts.com/crazy-egg-case-study/), proving the tool's target audience responds to exactly the kind of optimization CrazyEgg enables.

On the negative side, session recording limits and data export restrictions each draw 4 G2 mentions. Cross-referencing with migration data, these ceiling complaints map directly to the Hotjar and Clarity outflows. Companies that outgrow CrazyEgg's recording caps (50/month on Starter, 1,000 on Plus per crazyegg.com/pricing) have two choices: upgrade or switch to Clarity's free unlimited recordings.

Sales Signal: G2's "ease of use" signal combined with the 52% micro-business concentration means CrazyEgg customers value simplicity over power. Services providers should lead with quick-win optimization pitches, not enterprise-grade analytics programs.

7. Key takeaways

1. Late-blooming growth: CrazyEgg tripled its active install base from 2020 to 2024, reaching 30,593 domains at peak. The recent decline to 25,479 reflects competitive pressure, not product failure.

2. Small business core: 72.4% of customers have under 50 employees, but the 2.8% enterprise tail includes recognizable names like PwC, GE, Salesforce, and the BBC.

3. Horizontal appeal: No industry exceeds 6%, making CrazyEgg a genuinely cross-vertical tool. Retail leads, but healthcare, real estate, and software are nearly tied.

4. Competitive pressure from free tools: Microsoft Clarity's 4.3:1 gain ratio against CrazyEgg is the single biggest strategic threat. Companies that can get 80% of CrazyEgg's functionality for free are switching.

5. Stacking behavior: 11.21% HubSpot overlap confirms CrazyEgg users are marketing-stack builders, not standalone analytics users.

8. Sales applications

Outreach template: "Hi [Name], I noticed [Company] is running CrazyEgg on [detected URL]. Based on our analysis of 18,822 companies using the platform, businesses in [industry] typically pair it with HubSpot (11.21% do) and Tawk.to (6.40%). Are you looking to connect your heatmap insights to your marketing automation workflows? We help CrazyEgg users turn behavioral data into actionable campaigns."

Targeting strategy: On TechnologyChecker.io, filter for CrazyEgg + HubSpot + Retail or Medical Practices. This intersects the highest-overlap marketing tool with the two top industries, giving you prospects who are already investing in conversion optimization and have budget for tools.

Competitive angle: The 7,310 companies that left CrazyEgg for Microsoft Clarity in the last year may be underserved. Clarity is free but requires more manual configuration and lacks A/B testing, surveys, and error tracking (features CrazyEgg bundles). CrazyEgg's own pricing page confirms no overages and unlimited domains on every plan (source: crazyegg.com/pricing), giving it a predictable cost story that free tools with hidden complexity can't match. Position your services as the expertise layer that bridges the gap.
