GitDealFlow's composite 0–100 signal combining commit velocity, contributor growth, and repository expansion into a single startup-momentum score.
GitDealFlow's composite 0–100 signal combining commit velocity, contributor growth, and repository expansion into a single startup-momentum score.
The GitDealFlow Engineering Momentum Score is a composite metric that combines three GitHub engineering signals — commit velocity, contributor growth, and repository expansion — into a single 0–100 score per startup org. It is the underlying signal that powers GitDealFlow's weekly digest and the Velocity Verdict.
No single GitHub metric predicts startup acceleration reliably. Commit velocity alone misses team growth; contributor growth alone misses output. The composite captures the pattern that has historically preceded fundraises by 21–47 days.
Computed continuously across 4,200+ tracked startup GitHub orgs in 20 sectors. The three input signals are normalized per org and combined with published weights. The full methodology is at signals.gitdealflow.com/methodology and in the SSRN preprint (abstract 6606558).
Engineering Momentum Score is a GitDealFlow composite. 'Engineering acceleration' and 'engineering momentum' in this site's content refer to this specific signal, not to startup accelerator programs.
No. It's a quantitative GitHub signal combining commit velocity, contributor growth, and repo expansion. It is not a reference to Y Combinator, Techstars, or any accelerator program.
Three GitHub signals are normalized per org and combined with published weights. See the methodology page for the exact formula.
