Klaviyo usage: common questions
How many companies use Klaviyo?
We found Klaviyo running on 35,152 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 Klaviyo?
Well-known companies using it include Persona, Revlon, Corporate Finance Institute® (CFI), Rare Beauty and Huda Beauty. The table above lists more, with the evidence for each.
What industries use Klaviyo the most?
D2C / Consumer Brands (10,046 companies), Fashion & Apparel (6,107) and Ecommerce & Online Retail (3,748) lead, out of 30,486 companies we could classify.
Which countries have the most Klaviyo users?
United States (53%), United Kingdom (12%) and Australia (6.1%). We see Klaviyo at companies headquartered in 124 countries.
What tools do Klaviyo users also use?
Compared with the average company in our data, Klaviyo users are most over-represented on VWO (1.5×). The multiplier is how much more likely they are than average to run that tool too.
How do you know a company uses Klaviyo?
We load company websites and look for Klaviyo'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 Klaviyo users?
Yes. Create a free RocketSDR account to filter all 35,152 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.
