What this does not show

  • Stars measure attention, not revenue, adoption or retention.
  • The series starts on 3 Feb 2026, when we began observing this repository. Earlier history exists only as a monthly reconstruction and is deliberately not plotted with it.
  • A single launch post can produce a step like this without any change in usage.

We were tracking xbow-engineering/validation-benchmarks 43 days before this round was announced.

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