How does usedby know who uses Harness?
Each company is linked to a public page that names it: Harness'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 (39): a case study, a named quote or a press release. Observed (2): Harness shows the company on its own pages, for example a logo wall. Signal (0): a job post shows the company’s employees use Harness, the weakest proof. Every level counts as a customer, and each line shows its level.
How current is this list?
The most recent check was on October 7, 2026, and 41 of 41 companies on this list have been checked so far. 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.
