Questions, answered
How do I find out which companies use a technology?
Search for the tool above to see how many companies we track running it and how many verified contacts we hold there. To get the company names, request a free 10-record sample, or ask for the full list filtered by region, size, industry and job title.
Where do these counts come from?
Counts come from our technology detection (web footprint scans, job-post signals and partner directories) and, for tools without a public footprint, market research estimates. They are estimates; a live count for your exact criteria can differ.
Is the lookup free?
Yes. The lookup and the 10-record sample are free and need no sign-up for the lookup itself.
