Optimizely usage: common questions
How many companies use Optimizely?
We found Optimizely on the websites or inside the Android apps of 2,026 companies, as of 5 November 2026. 1,873 were detected on their website and 183 inside an Android app (30 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 Optimizely?
Well-known companies using it include BBC News, American Express, IKEA, CNN and Starbucks. The table above lists more, with the evidence for each.
What industries use Optimizely the most?
SaaS / Cloud (118 companies), Enterprise Software (109) and Retail (physical / general) (95) lead, out of 1,795 companies we could classify.
Which countries have the most Optimizely users?
United States (58%), United Kingdom (11%) and Australia (6.4%). We see Optimizely at companies headquartered in 63 countries.
What tools do Optimizely users also use?
Compared with the average company in our data, Optimizely users are most over-represented on Qualified (12.9×), 6sense (10.0×), Braze (9.4×). The multiplier is how much more likely they are than average to run that tool too.
How do you know a company uses Optimizely?
We load company websites and look for Optimizely'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 Optimizely's SDK in the code and manifest (213 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.
Can I export the full list of Optimizely users?
Yes. Create a free RocketSDR account to filter all 2,026 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.
