The Commit-Velocity Acceleration Engine is the published mechanism behind VC Deal Flow Signal. It pulls 14-day commit volume per organization from the public GitHub REST API, computes the percentage change against the prior window, requires two-period confirmation, scores contributor concentration with a Gini coefficient, then classifies each breakout into one of four signal types.
Full definition
The named mechanism behind VC Deal Flow Signal. Five deterministic steps: (1) pull 14-day commit volume per organization from the public GitHub REST API with the bot filter applied, (2) compute the percentage delta against the prior 14-day window, (3) require two-period confirmation before a breakout becomes actionable, (4) score contributor concentration with the Gini coefficient, (5) classify the breakout into one of four signal types (Hiring Burst, Infrastructure Buildout, Deploy Spike, Framework Migration). The engine is published, sourced, and reproducible, see /mechanism for the full formula and the SSRN proof panel. The engine is the formal implementation of the broader category: Code-Side Sourcing.
Why This Term Matters for Deal Flow
Commit-Velocity Acceleration Engine sits in the venture workflow where timing decides outcomes. GitDealFlow tracks public engineering momentum across 350+ startup GitHub organizations in 15 sectors, refreshed weekly, because repository acceleration is a leading indicator: breakout teams show up 21 to 47 days before the round is announced and the deck circulates. A term is not vocabulary for its own sake. It marks a decision point in sourcing, diligence, or portfolio monitoring where an objective, reproducible signal beats a warm intro or a stale database entry.
Three practical uses. Screening: when a term describes a stage or a mechanism, the question that matters is what evidence appears earliest at that stage, and public commit velocity, contributor growth, and repository expansion are among the earliest traces a startup leaves. Benchmarking: momentum scores computed from public data let an investor compare a target against sector peers on engineering execution rather than narrative. Monitoring: the same metrics that surface a breakout also flag deceleration, frequently the first warning of a down round or a stalled fundraise.
