A weekly composite leaderboard of the 100 startups with the strongest GitHub engineering signals across 19 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.
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.
