TL;DR, Finding 7 of 30
Engineering hiring bursts represent only 9% of observations (20 of 219).
Section §3.3 Signal classification · CC BY 4.0 · from the SSRN paper (DOI: 10.2139/ssrn.6606558)
Commit velocityis a 14-day rolling count of commits to a startup’s most active public repository, the earliest public signal of engineering throughput before a fundraise announcement. All 30 findings in this series are derived from the SSRN panel dataset of ~350+ tracked startup GitHub organizations.
The finding
Engineering hiring bursts represent only 9% of observations (20 of 219).
Why it matters
Refutes the dominant VC heuristic that 'more contributors = momentum.' It's the rarest meaningful signal type.
