What does “first seen in public” mean?
A line counts in this period when the first public copy showing it (an archived page or our own crawl) falls inside the period. Each line shows the range in which it appeared.
How this was built
This page is a snapshot: it shows what usedby knew on October 26, 2026 and never changes, except for dated corrections and names held back while the data is checked again.
Period: October 12, 2026 to October 18, 2026. A line counts when the first public copy that shows it (an archived page or our own crawl) falls in this period. Each line shows the range in which it appeared.
Proof levels, strongest first: confirmed means a case study, named quote, press release or the company’s own public account; declared means a direct company declaration to usedby or a sub-processor listing on the company’s own legal page; observed means the vendor shows the company on its pages; signal means a job post names the tool, the weakest proof. Every level counts as a customer. A sub-processor relationship does not describe a technical deployment or a result.
Scope: public lines on usedby only. A count is of companies on usedby, not a market share.
Limits: usedby sees only what is public. A company missing here may still use the tool.
