Top 100 GitHub-Signal Startups
A weekly composite leaderboard of the 100 startups with the strongest GitHub engineering signals across 15 sectors. The Signal Score combines four capped components, commit velocity change, contributor growth, raw commit scale, and contributor count, so no single metric dominates. Refreshed every Monday from the same dataset that powers the sector pages. If your question is which startups are moving now, this is the recurring shortlist page rather than a static startup database.
Quote-ready takeaway
The weekly Top 100 is not a verdict on the best startups. It is a shortlist of where public engineering momentum is concentrating right now.

How the Signal Score is calculated
SignalScore = clamp(velocityChange%, -20, 150)
+ clamp(contribGrowth%, 0, 150)
+ min(100, commits14d / 10)
+ min( 50, contributors / 2)Range −20 to 450. Capped components prevent a +999% velocity change on a 6-commit repo from out-ranking a steady org with 1,800 commits and 100 contributors. Same scoring is reused across every weekly edition so rank changes are comparable week-over-week.
