Clearbit usage: common questions
How many companies use Clearbit?
We found Clearbit running on 1,065 company websites, as of 3 November 2026. 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 Clearbit?
By LinkedIn following, the largest include Slack, Innodata Inc., Arm, Confluent, an IBM Company and Zendesk. The table above lists more, with the evidence for each.
What industries use Clearbit the most?
Software Development (386 companies), Technology, Information and Internet (113) and IT Services and IT Consulting (87) lead, out of 1,064 companies with a known industry.
Which countries have the most Clearbit users?
United States (58%), India (8.5%) and United Kingdom (6.1%). We see Clearbit at companies headquartered in 49 countries.
What tools do Clearbit users also use?
Compared with the average company in our data, Clearbit users are most over-represented on Warmly (18.3×), Clay (13.0×), Salesloft (11.6×). The multiplier is how much more likely they are than average to run that tool too.
How do you know a company uses Clearbit?
We load company websites and look for Clearbit's fingerprints: the scripts and network requests it makes, its cookies and response headers, DNS records, and tags configured inside Google Tag Manager containers. 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.
Can I export the full list of Clearbit users?
Yes. Create a free RocketSDR account to filter all 1,065 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.
