What the book covers
The seven signals, in the order the book teaches them:
- Commit velocity: sustained rises in weekly commits, the backbone signal.
- Contributor influx: new engineering hires appearing in public repos before any announcement.
- Star detachment: star growth decoupling from day-to-day engineering activity.
- Infra buildout: CI, deployment and tooling repositories multiplying ahead of a raise.
- Issue cadence: how fast a team closes its own backlog, a proxy for shipping discipline.
- Founding-team visibility: founders still committing code, a signal of pre-scale teams.
- Dependency adoption: fast integration of new infrastructure libraries by young teams.
Every chapter pairs the signal with the correlation evidence, the failure modes, and a worked checklist. The replication appendix re-derives each finding from the public dataset so you can check the work yourself.

What readers do with it
The book is written for investors who source: solo GPs building a first thesis, analysts at seed funds running weekly screens, and angels who want an edge that does not cost five figures a seat. Each chapter closes with a worked screen you can run the same afternoon with free tooling.
- Weekly routine: scan the momentum panel for accelerating teams in your sectors; breakout teams surface 21 to 47 days before their round is announced.
- On a hit: run the 20-minute GitHub due diligence checklist before anyone else sees the company.
- Ongoing: track the seven signals on your shortlist; the replication appendix shows exactly which thresholds matter.
Frequently asked questions
Is the book really free?
Yes. PDF, EPUB and plain-text editions download directly from this page with no email gate, no card and no upsell wall. The online chapters stay free as well.
What data is the book based on?
The GitDealFlow panel: 350+ venture-backed startup GitHub organizations across 15 sectors, tracked weekly, with the methodology published as an SSRN-indexed paper and a public replication appendix.
Does GitHub activity really predict fundraises?
No signal is perfect, and the book is explicit about failure modes. Sustained commit velocity and contributor growth correlate with Series A timing; the evidence, thresholds and false positives are all laid out chapter by chapter so you can judge yourself.
