How to Evaluate Engineering Velocity as a VC Signal

Engineering velocity is the strongest leading indicator of startup success. Teams that ship fast are teams that execute. This guide shows you how to read and interpret engineering velocity data.

Commit velocity measures how many code commits a team makes per week. Rising velocity suggests the team is scaling and shipping product fast. Falling velocity can indicate burnout, technical debt, or co-founder conflict.

Contributor growth tracks the number of developers committing code. A team growing from 3 to 8 contributors in a quarter is hiring and shipping — a strong positive signal.

Repository expansion tracks new public repos and code size growth. Teams creating new repos are exploring new product areas. Rapid repo creation can precede product launches.

GitDealFlow combines these three signals into a momentum score for each startup, normalized by sector. Top-quartile momentum predicts fundraises 3-6 weeks out with meaningful accuracy.

FAQ

What's a good engineering velocity for a startup?

It depends on sector. GitDealFlow normalizes by sector — a fintech startup's velocity looks different from a developer tools startup. Focus on relative momentum within the sector, not absolute numbers.

Does commit velocity equal product velocity?

Not always. Some teams commit often but ship little. GitDealFlow combines velocity with contributor growth and repo expansion to filter noise. Look for teams with rising velocity AND rising contributors.

Can engineering velocity be gamed?

Public GitHub activity can be inflated, but sustained velocity across months is hard to fake. GitDealFlow tracks 400+ startups over time, so anomalies stand out.
