Companies Using Microsoft Clarity

With 10+ years in web crawling and technographic data analysis, I've examined Microsoft Clarity's growth trajectory and customer profile using our 139,294 enriched company dataset (a 63% match rate against 220,035 active domains), as of our March 2026 crawl at TechnologyChecker.io. We matched Clarity domains against LinkedIn company profiles to uncover who actually uses this free behavioral analytics tool, where they're located, and what it means for the competitive analytics market.

Growth Trajectory

Microsoft Clarity didn't exist before October 2020. We detected 11 domains in its launch month. By January 2021, that jumped to 1,240. By April 2025, it had hit 233,082 active domains. That's a 20,000x increase in four and a half years. W3Techs (March 2026) independently confirms Clarity now runs on 3.7% of all websites, up from near zero in 2020.

The growth wasn't gradual. Three distinct phases stand out. Phase one (Oct 2020 – Dec 2021) was organic growth, reaching 14,155 domains. Phase two (2022-2023) brought steady compounding, hitting 90,123 by year-end 2023. Phase three (2024) was explosive: active domains doubled from 93K to 206K in a single year. What drove it? Microsoft quietly integrated Clarity with Bing Webmaster Tools, Copilot, and its advertising platform. Every SEO using Bing tools got nudged toward Clarity. The tool's "no traffic limits" promise sealed the deal for sites that couldn't justify Hotjar's per-session pricing.

"A 20,000x growth curve in 4.5 years doesn't happen on product quality alone. Microsoft pushed Clarity through Bing Webmaster Tools, Edge browser suggestions, and Azure integrations, making it the path of least resistance for any team that needs behavioral data." — Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: The free analytics market is expanding at roughly 80-100% year over year. If you sell premium analytics, CRO tools, or UX research platforms, your prospects are increasingly starting with Clarity as their baseline. Don't fight the free tool. Build on top of it. Position your product as the "upgrade when you outgrow Clarity" — because the 14 G2 reviews citing limited advanced features prove that a meaningful chunk of users hit that ceiling.

Customer Profile

Our enriched data paints a clear picture. 59.8% of Clarity companies have 1-10 employees. Combined with the 11-50 bracket (21.0%), that's 80.8% small businesses. The median company was founded between 2010-2019 (38.57% of the base), making the typical Clarity user a digital-native business about 7-15 years old.

But the enterprise tail is real. We detected Clarity on domains belonging to Deloitte, IBM, PwC, Oracle, Samsung, AT&T, and Shell. Don't mistake these for vanity installs. Look at the detection URLs: Shell runs Clarity on developer.shell.com. Starbucks uses it on coffeecommunity.starbucks.com. Cognizant has it on careers.cognizant.com. These are departmental deployments on specific properties where paying $200/month for Hotjar across every team isn't worth the procurement overhead. Clarity costs nothing. There's no PO to sign. That's the real enterprise value proposition.

Microsoft's published case studies confirm this pattern. Places for People (UK housing association managing 245,000 homes) reported a 63% increase in page views on their Careers section after using Clarity heatmaps to identify that 50% of users were clicking a "Current Vacancies" button and skipping all the employer branding content below it. They previously used Hotjar but switched to Clarity. TurkNet, a Turkish ISP, boosted ecommerce conversions by 107% using Clarity's session recordings, per Microsoft's published case studies. W3Techs independently confirms Microsoft.com, Samsung.com, Linktr.ee, and WordPress.com among the highest-traffic sites running Clarity. These aren't micro-businesses. They're organizations with real traffic and real conversion problems.

Sales Signal: The sweet spot for selling to Clarity users is companies with 11-200 employees (32% of the base) that have outgrown the free tool but haven't committed to enterprise-grade solutions. They've validated that behavioral analytics matters — now they need funnels, A/B testing, and ecommerce tracking. For the enterprise 1.4%, pitch Clarity as the entry point: "Your team already trusts Clarity. We extend it with [feature gap]."

Industry and Geographic Patterns

Retail leads at 6.55%, followed by Software Development (4.91%) and IT Services (4.51%). No industry breaks 7%. That's extremely horizontal for a web analytics tool. Compare this to Shopify (35%+ retail) or Salesforce (heavy financial services concentration). Clarity's flat industry distribution means it's not solving an industry-specific problem. It's solving a universal one: "Show me what users are doing on my website." Microsoft is now pushing Clarity deeper into ecommerce through its Brand Agents feature (announced January 2026 at NRF). Shopify merchants get Clarity integrated with Copilot checkout, which could shift the retail percentage significantly.

Geographically, the US leads with 29.4% (40,946 companies), the UK sits at 8.5% (11,840), and India ranks #3 at 7.0% (9,705). India's position is the most interesting signal here. Most Western analytics tools show India at #5 or #6. Clarity's free pricing removes the currency conversion barrier that makes $32/month Hotjar plans feel expensive in rupees. Brazil's #4 position (9,484) reinforces this pattern — Clarity over-indexes in cost-sensitive markets. For a deeper analysis of how different web analytics tools are adopted globally, see our Web Analytics Market Trends 2026 report.

Sales Signal: India at 7.0% and Brazil at 6.8% aren't just geographic data points. They represent markets where free tools dominate and paid alternatives struggle. If you're building a paid analytics product, these markets will be the last to convert. If you're building a freemium model with paid upgrades, these are your best top-of-funnel markets. Target the 40,946 US companies first for paid conversion, then UK and Australia.

Migration Patterns

The migration data tells the real competitive story. 17,099 companies switched from Hotjar to Microsoft Clarity while only 10,210 went the other way — a 1.7:1 gain ratio. In the last year alone, Clarity gained 4,448 from Hotjar and lost 1,183. That's a 3.8:1 annual ratio. The trend is accelerating.

The Google Analytics numbers need context. We see 61,230 companies that "left" Clarity and appear on Google Analytics. This isn't competitive displacement. GA and Clarity serve entirely different purposes — one tracks traffic sources, the other records user behavior. Most of these companies run both simultaneously. The overlap reflects companies experimenting with Clarity, then deciding they don't need behavioral analytics at all, not that GA replaced Clarity's functionality.

The FullStory migration is more telling: 2,933 companies switched from FullStory to Clarity, while only 1,206 went the other way (2.4:1 ratio). FullStory charges $300+/month for session recordings. When a free tool offers 80% of the same capability, the budget conversation becomes impossible for FullStory to win at the SMB level.

"The 1.7:1 Hotjar migration ratio isn't a product quality verdict. It's a pricing verdict. Clarity offers 70-80% of Hotjar's core features for 0% of the cost. Every quarter that ratio holds, Hotjar's addressable market shrinks to the segment that truly needs the premium 20%." — Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: Companies leaving Hotjar for Clarity are signaling budget pressure. They've decided behavioral analytics matters but the paid tool costs too much. Target these migrators with messaging that acknowledges the trade-off: "You switched to Clarity to save budget. Here's what you're missing — and here's how to get it for less than Hotjar." The 4,448 annual Hotjar-to-Clarity switchers are a built-in prospect list.

Technology Ecosystem

Klaviyo leads marketing automation companions at 12. For more context, see our marketing automation market share report.34% — meaning roughly 1 in 8 Clarity websites also runs Klaviyo. HubSpot follows at 9.55%. Together, these two represent the backbone of the marketing stack for Clarity's most sophisticated users. These aren't hobbyist websites. If you're running Klaviyo at $150+/month, you're a real business with revenue.

The CMS data shows Atlassian Cloud at 4. For more context, see our GA4 migration insights.3%, which is odd for a web analytics tool. It points to Clarity being deployed on Confluence-based knowledge bases and Jira service portals. Wix (2.71%) and Drupal (2.04%) reflect the broader website builder market. For ecommerce, Cart Functionality at 6.17% and Wix Stores at 2.32% show Clarity's presence in online shopping but at much lower rates than dedicated ecommerce analytics tools.

Live chat adoption is moderate: Brevo Live Chat (4.09%), Tawk.to (3.08%), and Intercom (2.74%). Notably, all three of the top live chat tools paired with Clarity have free tiers. The pattern is clear: Clarity users gravitate toward free and freemium tools across their entire stack.

Sales Signal: The Klaviyo (12.34%) and HubSpot (9.55%) overlap identifies your highest-value segment. These companies have proven marketing budgets. They're not using Clarity because they can't afford Hotjar — they're using it because the free tool is good enough for their behavioral analytics needs. To convert them, you need to show ROI that exceeds the $0 they're currently paying — and the feature gap data from G2 (A/B testing, ecommerce tracking, funnel visualization) gives you the specific capabilities to lead with.

G2 Review Analysis

Clarity scores 4.8/5 on Software Advice across 56 reviews and holds strong ratings on G2. The praise concentrates on three themes: free pricing (38 mentions), easy setup (29 mentions), and session recording quality (24 mentions). It's rare for "free" to be the #1 praised feature on G2 — usually it's functionality or support. This tells you Clarity's core value proposition isn't the product itself. It's the price.

The criticism is equally telling. Limited advanced analytics leads with 14 mentions: no A/B testing, no ecommerce event tracking, no funnel visualization. Data collection gaps (11 mentions) suggest the tracking script occasionally drops sessions. Limited integrations (9 mentions) reflect that Clarity only natively connects to Google Analytics and Bing tools. GDPR concerns (7 mentions) surface among European users worried about Microsoft processing session recording data. Drumline's enterprise guide (Nov 2025) notes that Clarity's built-in PII masking often satisfies compliance requirements faster than paid alternatives, but the 30-day data retention limit for recordings is a real constraint for enterprise analytics teams.

Here's what connects the review data to our crawl data: the 17,099 companies that switched from Hotjar to Clarity were probably influenced by the exact G2 sentiment we see — "Clarity does 80% of what I need for free." The 10,210 that switched back to Hotjar probably hit the limitations ceiling: they needed A/B testing, funnels, or deeper integrations that Clarity doesn't offer.

Sales Signal: The G2 criticism map is your feature-gap selling guide. A/B testing (14 mentions), ecommerce tracking (part of the "limited advanced analytics" bucket), and third-party integrations (9 mentions) are the top three reasons users outgrow Clarity. If your product fills any of these gaps, your pitch writes itself: "You love Clarity's free heatmaps. Add [your feature] for the analytics Clarity doesn't offer."

Key Takeaways

1. Clarity is the fastest-growing behavioral analytics tool on the web. From 11 domains to 233K+ in 4.5 years. Free pricing plus Microsoft's distribution channels created a growth curve that paid competitors can't replicate.

2. The user base is 80.8% small businesses, but the enterprise tail is real. Deloitte, IBM, PwC, Samsung, and Shell all run Clarity on specific properties. Enterprise adoption is departmental, not company-wide.

3. India (#3) and Brazil (#4) over-index. Free pricing eliminates currency barriers. These markets are where Clarity's growth advantage is strongest against paid competitors.

4. Clarity is winning the Hotjar battle at 1.7:1. Annual migration ratio is 3.8:1. The trend is accelerating. Hotjar's addressable market is shrinking to the premium segment that genuinely needs advanced features.

5. The tech stack overlap reveals marketing-savvy users. Klaviyo (12.34%) and HubSpot (9.55%) adoption means Clarity users aren't budget-constrained hobbyists. They're running real businesses that happen to prefer a free analytics tool.

6. G2 confirms the "good enough" disruption pattern. Free pricing praised most. Limited features criticized most. Classic low-end disruption that works until the free tool adds the missing features — which Microsoft has the resources to do.

Sales Applications

Outreach template for Clarity users:

"Hi [Name], I noticed [Company] runs Microsoft Clarity alongside [HubSpot/Klaviyo/no A/B testing tool]. Our data shows Clarity users most commonly upgrade when they need [A/B testing / ecommerce tracking / funnel visualization]. Are you hitting any of those limits? Happy to share what we're seeing from similar [industry] companies making the switch."

Targeting strategy: Filter the Clarity install base by company size (11-200 employees), industry (retail or software), geography (US or UK), and tech stack (running Klaviyo or HubSpot). This narrows to companies with proven marketing budgets who've outgrown free tools across every category except behavioral analytics. That's your conversion-ready segment.

Competitive angle: Don't position against Clarity's price — you'll lose that fight. Position against its feature gaps. The G2 data gives you three specific angles: A/B testing, ecommerce tracking, and third-party integrations. Frame it as "Clarity + [your product]" not "Replace Clarity with [your product]." Microsoft made the heatmaps free. Sell the layer on top.
