Clay usage: common questions
How many companies use Clay?
We found Clay running on 1,636 company websites, as of 5 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 Clay?
Well-known companies using it include TASC Outsourcing, Aquent, Mercor, Thoughtworks and Confluent, an IBM Company. The table above lists more, with the evidence for each.
What industries use Clay the most?
SaaS / Cloud (428 companies), AI / ML (414) and Enterprise Software (413) lead, out of 1,563 companies we could classify.
Which countries have the most Clay users?
United States (58%), United Kingdom (12%) and Canada (3.8%). We see Clay at companies headquartered in 46 countries.
What tools do Clay users also use?
Compared with the average company in our data, Clay users are most over-represented on Chili Piper (34.6×), 6sense (14.7×), Qualified (12.6×). The multiplier is how much more likely they are than average to run that tool too.
How do you know a company uses Clay?
We load company websites and look for Clay'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.

Yes. Create a free RocketSDR account to filter all 1,636 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.
