VC GitHub Lookup — Startup Signals on Hover

Hover any GitHub repo or org to see VC-grade engineering signals: commit velocity, contributor growth, and breakout status.

See VC-grade engineering acceleration data overlaid on every Crunchbase and Wellfound startup profile. Spot breakout startups before anyone else. When you open a company profile on Crunchbase or Wellfound, an inline badge appears showing the live engineering signal: • "Accelerating" — commit velocity up sharply vs the company's own baseline • "Steady" — within normal range • "Decelerating" — velocity down vs prior period • "No data" — company not in our public dataset yet Hover the badge for the underlying metrics: 14-day commit velocity, velocity change vs prior period, contributor count and growth, and the engineering signal type (hiring burst, infrastructure buildout, framework migration, deploy-frequency spike). Data comes from GitDealFlow's public sector rankings — built from the public GitHub API across ~4,200 candidate startup organizations, refreshed weekly, and free to browse at https://signals.gitdealflow.com. Marketing site, methodology, and SSRN preprint: https://gitdealflow.com (the /chrome page lists both extensions and the data flow). Privacy: • No analytics, no tracking, no account required. • Reads only the company slug from the URL of the page you're on. • One outbound request to https://signals.gitdealflow.com per profile load. • No host-page content collection, no DOM beyond the URL. Companion extension: "VC GitHub Lookup — Startup Signals on Hover" (https://chromewebstore.google.com/detail/vc-github-lookup-%E2%80%94-startu/plgngijmloeljfkenecdkhiblcfcbblm) puts the same signal on every GitHub repo or org page. Install both for the complete loop — the deal-research surface (Crunchbase, Wellfound) AND the engineering-origin surface (GitHub itself). Free in perpetuity. Manifest V3, ~30 KB.
