Top 100 GitHub-Signal Startups, Week 18, 2026

91 distinct startups ranked across 18 sectors. Top Signal Score this week: 353.5 (harvard-edge). Median Signal Score: 60.4.

SignalScore = clamp(velocityChange%, -20, 150) + clamp(contribGrowth%, 0, 150) + min(100, commits14d / 10) + min(50, contributors / 2). Capped components prevent any single metric from dominating. Higher = more engineering momentum relative to baseline + raw scale.
