Scout Score: A GitHub Investment Track Record
Scout Score (0-100) grades any GitHub user's starring history against a curated database of validated unicorns. Free tool, no login, instant shareable card. Free MCP tool included.
Scout Score is a 0-100 metric that grades a GitHub user's investment taste based on their starring history. It answers the question: of the validated unicorns and big-funding events that happened in the last five years, how many did this person star *before* the event?
How it's computed. GitDealFlow maintains a curated database of ~75 validated wins — companies that hit a $1B+ valuation, raised a Series A or later, were acquired, or crossed 25K+ stars. For each user, the algorithm pulls their public starring history, cross-references each starred repo against the wins database, and computes points: weight × min(months_early / 24, 1.0), capped at weight. Top 5 wins by points are summed and normalized so 5 perfect early calls = 100.
Rank ladder. Curious (0-19), Scout (20-39), Sharp (40-59), Elite (60-79), Oracle (80-100). The rank shows up in the user's profile card and the public leaderboard.

Frequently asked questions
Does Scout Score read my private repos or DMs?
No. The tool reads only the public starring history that GitHub already exposes via its REST API. No OAuth, no private repos, no DMs.
How do I show off my score?
Use the badge builder at `/badge-builder` to generate a markdown snippet you can paste into your `github.com/{username}/{username}` profile README. The badge auto-updates as your starring history grows.
Can I improve my score?
Receipts are backwards-looking — past stars don't change. The forward-looking counterpart is `/predict`, the Scout game, where you call whether a GitHub org will raise a Series A in 6 months. Predictions auto-resolve at the 6-month window.
