VC GitHub Lookup — Startup Signals on Hover

Tracking since May 5, 2026.

Changelog

• May 10, 2026
  description

  VC GitHub Lookup turns GitHub itself into a deal-flow surface. Hover any repo or org and instantly see the data investors and engineering leads use to spot breakout startups before anyone else:
  
    • Commit velocity (last 14 days)
    • Velocity change vs. prior period
    • Contributor count and growth
    • Engineering signal type (hiring burst, reorg, breakout, …)
    • Stage estimate
  
  When you visit a repo or org page directly, a chip is injected next to the page header so the data is always one glance away. The toolbar icon opens a manual lookup form for any GitHub org or URL.
  
  Data comes from GitDealFlow's public sector rankings — built from the public GitHub API, refreshed continuously, and free to browse at https://signals.gitdealflow.com.
  
  Privacy:
    • No analytics, no tracking, no account required.
    • The only network request is to https://signals.gitdealflow.com — only when you hover a GitHub link or open the popup.
    • The owner slug is sent in the URL; nothing else is collected.
    • Responses are cached in session storage (≤5 minutes) so the API stays friendly.
  
  Companion extension: "VC Deal Flow Signal" (https://chromewebstore.google.com/detail/hehkgipiamajnnlpkfhpeoeaoaogmknn) surfaces the same signals on Crunchbase and Wellfound profiles. Install both for a complete loop.

  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.
