Every dev has invested in unicorns.
They just don’t know it.

Your GitHub stars are receipts. Paste your username and we’ll show you every unicorn / Series A / big acquisition you starred before the news broke. Get your Scout Score and a shareable card in under 8 seconds.

Try it on a public dev:

TL;DRGitHub Receipts is a free, no-login tool that grades any developer's GitHub starring history against a curated database of ~75 validated unicorns. Paste a username, get a Scout Score (0-100), a rank from Curious to Oracle, and a shareable 1200×630 OG card. Same data is available via /api/receipts/{username}, an embeddable SVG badge, and the get_scout_receipts MCP tool.

Scoring is deterministic: months_early × weight, capped at 24 months early. Top 5 wins normalized so 5 perfect early calls = 100. (Methodology)
Embeddable Scout Score badge endpoint at /api/badge/scout/{username}/svg renders a shields.io-style SVG, CDN-cached 24h. (Badge builder)
Free MCP tool — get_scout_receipts(github_username) — exposes the same scoring from Claude Desktop, Cursor, Windsurf, and any MCP host. (agents.md)

How the score works

01We pull your public starred repos from the GitHub API (no login, no OAuth, no private data).
02We cross-reference each repo against our database of ~75 validated unicorns — companies that hit a $1B+ valuation, raised a Series A+, were acquired, or crossed 25K+ stars in the last 5 years.
03For every match, we compare your star date vs the event date. The earlier you starred, the more points. Late stars are worth zero.
04Top 5 wins are summed and normalized to a 0–100 Scout Score. Five perfect early calls = 100. You get a rank from Curious to Oracle.

Receipts are backwards. The Scout game is forwards.

Receipts grade your past. The Scout game tracks your future. Pick any GitHub org and predict whether they raise in 6 months — we resolve every call automatically. Free tier: 3 predictions a month. Top 1% earn an Oracle badge.

We never read private repos, DMs, or starred lists you’ve made private. Read the methodology.
