GitHub Maintainer Lead Finder

Finding people who actually maintain the open-source tools your buyer already uses beats a cold list from a generic B2B database — they're active, technical, and self-selected into exactly the space you're selling or hiring into. This searches GitHub for repos matching your criteria and turns their top contributors into a scored, outreach-ready lead list.

What it does

1. Searches GitHub for repos matching your language, topics, minimum stars, and recent-activity window.
2. Pulls each matching repo's top contributors by commit count.
3. Looks up each contributor's public GitHub profile — name, company, email (when they've chosen to make one public), blog, location, followers.
4. Scores each lead 0–100 on reachability: public email, listed company, personal site, follower count, and how much they've actually contributed.
5. Flags core_maintainer (50+ commits to this repo) and high_influence (500+ followers) so you can prioritize.
6. Drops anything failing your filters before billing.

A note on email coverage

GitHub hides profile emails by default — most contributors, even prolific ones, won't have one public. That's real signal, not a bug: no_public_email shows up in opportunitySignals so you can see at a glance who you'll need to reach through their listed company or blog instead. Turn on requireEmail if you only want the subset with one.

Input

You need your own free GitHub personal access token — GitHub allows only 60 unauthenticated requests per hour, which isn't enough for a real run. Create one with no scopes at github.com/settings/tokens; public data doesn't need any permissions.

{
  "githubToken": "ghp_...",
  "language": "python",
  "topics": ["cli"],
  "minStars": 500,
  "pushedSinceDays": 90,
  "maxRepos": 20,
  "maxContributorsPerRepo": 3
}

Pricing

Pay per event. You're billed per lead returned and once per repo digested, not for the GitHub API calls themselves.
