What this does not show

  • Stars measure attention, not revenue, adoption or retention.
  • The series starts on 2 Feb 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 round above was announced on 27 Mar 2023, outside the window we measured, so this page makes no before-and-after claim about it.

We have been recording fixie-ai/ultravox since 2 Feb 2026.

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