- Star slope visible months before the round; release of v1.0 in August 2022 was the on-ramp
Astro positioned itself as a content-first web framework — different enough from Next.js or Remix to carve its own audience. The repo's growth was slow-and-steady rather than viral; what made it investable was the consistency.
The August 2022 v1.0 release crystallized the project's API and unlocked a wave of new contributors. Two months later Felicis led the $7M Series A. The engineering signal — release cadence, contributor growth, blog post density — preceded the round by months.
Astro's case shows that you don't need a 100K-star repo to attract a credible Series A. A coherent thesis plus measurable, sustained engineering acceleration is enough.

Frequently asked questions
Did the Series A price the framework or the company?
Both. Felicis was underwriting Astro as a platform play, with the framework as the open-source funnel.
How predictable was the Series A?
Reasonably. A v1.0 milestone on a framework with growing star slope is a strong leading indicator.
