PostHog usage: common questions
How many companies use PostHog?
We found PostHog on the websites or inside the Android apps of 5,186 companies, as of 5 November 2026. 4,604 were detected on their website and 614 inside an Android app (32 both). This counts companies we can tie to a LinkedIn company page, so it is a floor, not a market total.
Which well-known companies use PostHog?
Well-known companies using it include Crossover, Airbus, Nokia, Y Combinator and We Work Remotely. The table above lists more, with the evidence for each.
What industries use PostHog the most?
AI / ML (676 companies), SaaS / Cloud (485) and IT Services & Consulting (304) lead, out of 4,128 companies we could classify.
Which countries have the most PostHog users?
United States (40%), India (27%) and United Kingdom (6.2%). We see PostHog at companies headquartered in 98 countries.
What tools do PostHog users also use?
Compared with the average company in our data, PostHog users are most over-represented on Intercom (4.3×), Segment (2.9×), Clay (2.9×). The multiplier is how much more likely they are than average to run that tool too.
How do you know a company uses PostHog?
We load company websites and look for PostHog's fingerprints: the scripts and network requests it makes, its cookies and response headers, DNS records, and tags configured inside Google Tag Manager containers. We download and decompile Android apps from Google Play and look for PostHog's SDK in the code and manifest (1,048 scanned apps embed it), then match each app to the company that publishes it. A company is only counted when we can tie the domain or app to its LinkedIn company page, and shared domains (link shorteners, site builders) are excluded, so a domain scan of bit.ly never counts as evidence about a brand that links to it.

Yes. Create a free RocketSDR account to filter all 5,186 companies by industry, size and country, find the right contacts, and start outreach. Developers can query the same data through the gtm.dev who_uses_tech API.
