Signal definition
Indicates a startup is moving from prototype to production. Often appears 4–8 weeks before a public launch announcement.
Unit: binary signal (fires / does not fire) · Window: 30-day window
fires when ≥3 of {Dockerfile, k8s manifest, terraform/, .github/workflows/, deployment config} are added/modified within a 30-day windowStrongest weight when paired with the first appearance of a billing/auth dependency in package.json (e.g. stripe, clerk, auth0) — indicates production readiness.
Open-source libraries publish infra (Dockerfiles, GitHub Actions, k8s charts) for distribution, not for their own use. We score down repos with library-shape signals (semver tags, npm/pypi presence).
