Where it is now

Running slower than its own average

What this does not show

  • Stars measure attention, not revenue, adoption or retention.
  • The series starts on 8 Jun 2026, when we began observing this repository. Anything earlier survives only as a monthly reconstruction that does not join up with these readings, so it is not plotted.
  • The Series A above was announced on 5 May 2026, outside the window we measured, so this page makes no before-and-after claim about it.

We have been recording CopilotKit/CopilotKit since 8 Jun 2026.

Finding companies at that stage is the product. Contributor pedigree, enterprise-demand signals and our ranking sit behind the login.
