PlanetScale's GitHub footprint is intentionally small — the product is a hosted MySQL service. The CLI repo carried the technical brand, but the *real* signal was partnership-announcement density.
By late 2021 PlanetScale was the recommended database in Next.js + Prisma tutorials, with co-marketing across the dev-tool ecosystem. That kind of partnership density is a strong leading indicator for SaaS rounds.
The $50M Series C at $1B closed in February 2022 — a unicorn-tier outcome on top of a signal that had been visible in the partnership graph for a year.
Signals that would have flagged this pre-raise
