Calendly usage: common questions
How many companies use Calendly?
We found Calendly running on 11,158 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 Calendly?
Well-known companies using it include Deutsche Bank, Sopra Steria, Weekday (YC W21), RWS and Programming.com. The table above lists more, with the evidence for each.
What industries use Calendly the most?
IT Services & Consulting (1,215 companies), Software Development (custom / web / mobile) (918) and AI / ML (896) lead, out of 9,098 companies we could classify.
Which countries have the most Calendly users?
United States (36%), India (25%) and United Kingdom (7.6%). We see Calendly at companies headquartered in 122 countries.
What tools do Calendly users also use?
Compared with the average company in our data, Calendly users are most over-represented on Intercom (1.7×). The multiplier is how much more likely they are than average to run that tool too.
How do you know a company uses Calendly?
We load company websites and look for Calendly'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 Calendly users?
Yes. Create a free RocketSDR account to filter all 11,158 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.
