Seven GitHub signals. Seven days. Seven 5-minute exercises you can run yourself on any public startup. End the week with a sourcing framework that works without any tool — drawn directly from the SSRN-published methodology covering 219 confirmed venture rounds.
Commit velocity
The simplest acceleration signal. 14d-vs-90d ratio, sustained vs. spike, single-repo vs. org-level read.
Contributor diversity
Why a single-bus-factor codebase tanks the round. Gini coefficient at month -3, the 4-contributor floor.
Dependents graph
GitHub's hidden dependents page. The cheapest external-adoption proxy. Cross-portfolio warm-intro vector.
README freshness
The under-rated leading indicator. Substantive-diff filter. The 'Funding' section that just appeared.
New repo creation rate
The platform-buildout tell. SDK / CLI / example-app pattern. The 'deploying capital' signal.
Issue-to-PR ratio
Engagement vs. shipping. Why a 1.5+ ratio is healthy and a 0.7 ratio means the round is firefighting.
The composite + the fast version
Compose all six signals into one score. Then see how it runs across 4,200 venture-backed orgs in 4 seconds.
Free. No card, no trial, no hidden upgrade pressure. The seven emails are the course; Day 7 mentions three optional paths but you keep the framework either way.
Five minutes a day. Each email gives a numbered procedure that runs entirely inside github.com — Insights, Pulse, Contributors, Dependency graph. No tool, no API, no sign-up.
No. If you have ever opened a repo on github.com, you have everything you need. The exercises read what is already on screen and combine simple counts.
Panel analysis of 219 confirmed venture rounds, published as GitHub Signals as Leading Indicators of Venture Fundraising on SSRN (abstract id 6606558). Each daily email maps to one signal in the paper.
The Sunday digest is the applied product — five named startups every week. The Challenge is the framework — the underlying signals so you can run the analysis yourself on any startup, not only the ones we surface.
