Companies Using Amplitude

With over 10 years in web crawling and technographic data analysis, I've spent the past year tracking Amplitude's position in the product analytics market. This analysis draws on 27,946 enriched company profiles matched from our detection of 73,732 active Amplitude domains (a 41.6% match rate), cross-referenced with G2 review data, Amplitude's published case studies, and the company's Q4 2025 earnings release ($343.2M FY revenue, $366M ARR, 4,700+ customers). Our data represents the broadest independent view of Amplitude's customer base as of our April 2026 crawl.

Growth trajectory

Amplitude's adoption curve tells a clear story. From its first detection in May 2014 (two years after its 2012 founding by Spenser Skates and Curtis Liu), the platform grew slowly through 2017, reaching just 252 active domains. Then something changed. In 2018 alone, active domains jumped from 252 to over 2,000, an 8x increase in a single year. That growth coincided with the launch of Amplitude's free tier. The company raised $336M total across 11 funding rounds (per Tracxn), including a $150M Series F led by Sequoia Capital at a $4B valuation in June 2021 (per Amplitude's press release).

The trajectory steepened further after Amplitude's September 2021 direct listing on Nasdaq at an implied $6.4B valuation (per Forge Global). Between 2021 and early 2025, active domains tripled from 5,339 to 16,437. Amplitude peaked in April 2025 at 16,437 active domains before pulling back to 11,995 by July 2025. The company's ARR tells a different story: it hit $366M in Q4 2025, up 17% YoY, with 698 customers above $100K ARR (up 18%) and 56 above $1M (up 33%).

"An 8x jump in a single year (2018) is rare in product analytics. It signals that Amplitude's free tier didn't just attract tire-kickers; it converted developers into advocates who brought the tool into their companies." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: The 2018 inflection point and post-IPO tripling confirm an expanding addressable market. Target companies that adopted Amplitude between 2020-2023, as they're likely outgrowing the free tier and ripe for upgrade conversations or complementary tool sales.

Customer profile

Amplitude's customer base splits into two distinct segments. The bulk, 60.99% with 1-10 employees, are startups and small product teams running the free Starter plan. Add the 11-50 range (24.62%) and you've got nearly 70% of Amplitude's base at under 50 employees. These are digital-native companies: 41.89% were founded in the 2010s, 26% in the 2020s. Only 2.33% predate 1960.

But the enterprise tail is significant. Our top 50 detected companies are all 10,001+ employees, including Broadcom, NVIDIA, Hewlett Packard Enterprise, Burger King and Ascension. Several of these align with published case studies with hard metrics. NBC reported 2x Day 7 retention and a 36% conversion lift. Jersey Mike's doubled mobile app orders with an 80% revenue increase. Walmart used Amplitude during its 2020 app consolidation, merging grocery and general merchandise apps during a period of record downloads. Square has 100+ employees using Amplitude daily as their central source for user insights. The detection URLs in our data tell an important story too. Detections sitting on brand microsites and regional subdomains rather than on flagship domains suggest departmental deployments rather than wall-to-wall rollouts.

Sales Signal: The 60.99% micro-business concentration creates a massive pipeline of companies that will outgrow free plans. Meanwhile, enterprise detections on specialized subdomains suggest an expansion play: teams that adopted Amplitude in one department are candidates for cross-organization deals.

Industry and geographic concentration

Software Development leads at 12.75%, followed by Technology, Information and Internet at 8.01%. Together, tech-adjacent industries account for over 25% of the customer base. Retail (3.88%) and Financial Services (3.12%) round out the top five, but no vertical exceeds 13%. This is a genuinely horizontal platform with a clear tech-first center of gravity.

Geographically, the United States accounts for 45.4% of enriched customers, followed by India (7.3%) and the UK (6.4%). English-speaking markets (US, UK, Canada, Australia) combine for 57%+. The India concentration is notable and probably reflects the country's booming SaaS and startup ecosystem, not just outsourced development teams.

Sales Signal: Non-English markets (France at 2.5%, Germany at 2.3%, Spain at 2.0%) are underrepresented relative to their tech economies. European expansion, especially in DACH and Southern Europe, could be a growth corridor. Vertical-specific plays in financial services and healthcare (where compliance requirements favor established analytics vendors) present targeted upsell opportunities.

Migration patterns

The migration data reveals a mixed competitive picture. Against its closest rival Mixpanel, Amplitude holds a 1.3:1 gain ratio (976 gained vs. 735 lost). That's a modest but consistent advantage, concentrated in the 3-5 year time window rather than the last 12 months (only 90 gained from Mixpanel in the past year).

The largest flows involve Hotjar and Microsoft Clarity, where Amplitude is a net loser. Amplitude lost 4,389 domains to Hotjar and 4,255 to Microsoft Clarity, while gaining 1,828 and 1,106 respectively. But these aren't apples-to-apples comparisons. Hotjar and Clarity focus on session replay and heatmaps, not event-based product analytics. Companies aren't replacing Amplitude with Clarity; they're adding Clarity alongside or dropping Amplitude's session replay feature in favor of a free alternative.

"The Mixpanel-to-Amplitude corridor is the real competitive signal here. A 1.3:1 gain ratio over five years confirms Amplitude is winning head-to-head matchups, even as free tools like Clarity capture the session replay market Amplitude once contested." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: Companies that recently dropped Mixpanel for Amplitude (976 in total) are validated converts worth targeting with complementary services. The 4,255 companies that moved to Microsoft Clarity didn't necessarily leave Amplitude entirely; they may have dropped a secondary analytics tool, creating a re-engagement opportunity.

Technology ecosystem

The tech stack data reveals what kind of companies use Amplitude. HubSpot leads at 23.78% overlap (combining HubSpot core + Hosted + Ads + COS), making it the dominant marketing automation choice. Klaviyo at 8.76% reflects the ecommerce segment within Amplitude's base.

The JavaScript framework distribution is telling. RequireJS (13.96%) and AngularJS (12.63%) sit at the top, suggesting many Amplitude customers run mature, enterprise-grade web applications rather than greenfield React projects. Emotion (12.06%) and styled-components (10.37%) point to a substantial React/CSS-in-JS segment as well. In e-commerce, Magento (6.03%) leads over Webflow Ecommerce (2.63%), consistent with Amplitude's enterprise tilt.

Sales Signal: The HubSpot overlap at nearly 24% creates a clear co-selling corridor. Companies running both tools already invest in data-driven growth. The AngularJS/RequireJS prevalence suggests a mature application stack, meaning longer sales cycles but stickier customers. Alpine.js (2.36%) and Svelte (1.96%) indicate an emerging cohort of modern framework adopters worth watching.

G2 review signals

Amplitude holds 4.5/5 stars from 3,223 verified G2 reviews (per G2) and has been #1 in Product Analytics for 23 consecutive G2 quarters. The 2025 Forrester Wave named it a Leader and Customer Favorite in Digital Analytics, with the highest Current Offering score and 5/5 in 21 criteria including AI for Insights. The top G2 pro, "powerful insights" (336 mentions), aligns with Amplitude's positioning. Ease of use (315 mentions) ranks second, which is notable given the top con is "steep learning curve" (139 mentions). That contradiction resolves when you look at who's reviewing: data analysts find it intuitive, while product managers struggle with event tracking setup.

The learning curve complaint (combined 277+ mentions) tracks with our migration data. NBC's VP of Product called Amplitude "data science in a box", while noting it gave analysts back 25% of their day. Non-technical users who can't reach that level gravitate toward simpler tools like Hotjar or Clarity.

Sales Signal: Onboarding and training services are a clear gap. The 277+ learning curve mentions represent real pain. Companies that invested in Amplitude but struggle with adoption are candidates for implementation partners, training workshops, or managed analytics services. The "missing features" complaint (78 mentions) could signal demand for Amplitude's newer products like Session Replay and AI features.

Key takeaways

1. Second, and the gap is a pricing model: 73,732 active domains is 28.08% of product analytics, against PostHog's 45.59%. PostHog's open-source free tier reaches a long tail Amplitude never sells to.

2. Two-tier customer base: 60.99% micro-businesses on free plans, plus a Fortune 100 enterprise tail (26% of Fortune 100 per Amplitude's own claims). The gap between these segments defines the monetization challenge.

3. Winning vs. Mixpanel: A 1.3:1 gain ratio over 5 years. The head-to-head battle favors Amplitude, though recent momentum has slowed.

4. Losing to free tools: Net losses to Hotjar and Microsoft Clarity reflect the session replay market fragmenting, not core product analytics churn.

5. Tech-first, US-centric: 25%+ tech-industry concentration and 45% US share. International expansion is the obvious growth lever.

6. Enterprise signal: Detection on brand portals and internal subdomains at companies like Broadcom and Hewlett Packard Enterprise suggests departmental adoption with room for expansion.

7. AI pivot in progress: Five AI acquisitions since October 2024, "tens of millions" invested per CEO Spenser Skates (per Business Insider). Agentic AI analytics (Global Agent, Specialized Agents) shipped in Q4 2025, and MCP integration brings Amplitude data into Claude, Cursor, Slack, and Figma.
