OpenAI usage: common questions
How many companies use OpenAI?
9,482 companies have verified their domain with OpenAI, 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 OpenAI?
Well-known companies using it include The Wall Street Journal, Boston Consulting Group (BCG), Bain & Company, Zoho and Thomson Reuters. The table above lists more, with the evidence for each.
What industries use OpenAI the most?
IT Services & Consulting (761 companies), AI / ML (582) and Enterprise Software (577) lead, out of 8,088 companies we could classify.
Which countries have the most OpenAI users?
United States (42%), India (19%) and United Kingdom (5.3%). We see OpenAI at companies headquartered in 114 countries.
What tools do OpenAI users also use?
Compared with the average company in our data, OpenAI users are most over-represented on Cursor (16.8×), Notion (15.0×), Claude (8.4×). The multiplier is how much more likely they are than average to run that tool too.
How do you know a company uses OpenAI?
OpenAI asks companies to publish a DNS TXT record ("openai-domain-verification=…") to prove they own their domain — an admin step taken when setting up a company workspace or account. We read public DNS records for company domains and count the ones carrying that record. 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 9,482 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.
