How does usedby know who uses C3 AI?
Each company is linked to a public page that names it: C3 AI's customer page, a published case study, a press release or a job post. We save each page with a dated capture and check it again on each run. A company leaves the list only after three checks in a row that no longer find it, and at least 14 days after it was last seen. A company with a published case study or quote is never removed automatically.
What do confirmed, observed and signal mean?
Confirmed (23): a case study, a named quote or a press release. Observed (12): C3 AI shows the company on its own pages, for example a logo wall. Signal (0): a job post shows the company’s employees use C3 AI, the weakest proof. Every level counts as a customer, and each line shows its level.
