GitHub Lead Signals + AI — Companies & Developers by Tech Stack

Find the companies and developers who already use a technology on GitHub and turn them into AI-scored B2B sales leads. Give it a technology or search term (e.g. stripe connect, langchain, kubernetes operator) and get back the GitHub accounts using it — enriched with their public profile plus an AI read of why they're a fit, a buying-intent signal, a sales angle, and a personalized outreach opener.

Built-in AI. No OpenAI / OpenRouter API key required. No GitHub token required.

Why "who uses this tech" is a buying signal

What an account builds with tells you what it's in the market for:

• A company with Stripe Connect repos → building marketplaces/payments → needs payments tooling, fraud, reconciliation, monitoring.
• A developer shipping LangChain / LLM repos → an AI builder → needs vector DBs, eval tools, GPU/inference.
• An org with Kubernetes operators → running cloud-native infra → needs observability, security, cost tooling.

Most GitHub scrapers just dump repos. This actor reads GitHub's public REST API (no anti-bot pain), dedupes to the account behind the repos (your actual lead), enriches their profile, and adds the layer that matters: what it means for you.

Input

Example input

{
"searchQueries":["stripe connect","langchain"],
"minStars":50,
"ownerType":"any",
"maxLeads":50,
"enrichProfiles":true,
"aiSignals":true,
"offerDescription":"We sell a developer-focused API monitoring and observability platform.",
"aiLanguage":"English"
}

Output

One row per unique lead (company or developer):

{
"login":"stripe",
"ownerType":"Organization",
"profileUrl":"https://github.com/stripe",
"company":null,
"email":"support+github@stripe.com",
"location":"San Francisco, CA",
"followers":3247,
"matchedRepoCount":3,
"totalStars":869,
"languages":["Swift","TypeScript","JavaScript"],
"topRepos":[
{"fullName":"stripe/stripe-node","stars":400,"language":"TypeScript"}
],
"leadType":"Company",
"techStack":["TypeScript","Node.js","Stripe","Stripe Connect"],
"fitScore":85,
"intentSignal":"Repos focus on Stripe-powered payment platforms — strong need for reliable API monitoring.",
"salesAngle":"Emphasize reliability of their Stripe integrations in high-transaction environments.",
"personalizedOpener":"I noticed your work with Stripe Connect — ensuring those transactions run smoothly is exactly what we help with.",
"bestContactChannel":"email",
"aiAnalyzed":true
}

How it works

1. Searches GitHub's public REST API for repositories matching each query (with your language / minStars filters).
2. Dedupes by owner — many repos can belong to one account; your lead is the account, with its top matching repos aggregated.
3. Optionally enriches each lead's public profile (company, email, website, location, Twitter, followers, bio).
4. Runs one AI call per lead to score fit (0–100), summarize the buying-intent signal, suggest a sales angle, and write a personalized opener tied to their real repos.
5. Saves one clean lead row per account.

IPs are rotated automatically via Apify Proxy to stay under GitHub's unauthenticated rate limits, so larger runs keep flowing.

Tips

• Add an offerDescription to get openers and a fit score tailored to your product.
• Use ownerType: "organizations" for B2B company lists, or "users" to recruit / reach individual builders.
• Combine tech terms in searchQueries (e.g. langchain, llamaindex, vector database) to widen an ICP in one run.
• Raise minStars to focus on established, better-resourced accounts.

FAQ

Do I need a GitHub or AI API key? No. It uses GitHub's public REST API and Apify's built-in AI model — nothing to manage.

Is email always present? Only when the account has published a public email on GitHub. Many do; many don't. You also get website, Twitter and location to reach the rest.

Will I get blocked? No. It reads the public JSON API and rotates IPs via Apify Proxy to respect GitHub's rate limits.

Why dedupe to the owner instead of one row per repo? Because your lead is the company or developer, not each repo. One clean row per account keeps your outreach list tidy — with the top matching repos and aggregate signal attached.

Can I turn AI or enrichment off? Yes. Turn off aiSignals for raw leads, or enrichProfiles for just the GitHub accounts — both lower cost.

Related Actors — build a full pipeline

This Actor is the "find who uses the tech" step. Pair it with the others to go from signal → enriched contact → outreach:

• GitHub Lead Signals (this Actor) finds accounts using your target tech → feed companies into AI Lead Enricher to pull site profile, emails and a cold-email opener.
• Combine with Hiring Signals (AI) to cross-reference who's both using your tech and hiring for it — the strongest possible buying signal.

Workflow: GitHub Lead Signals (tech intent) → AI Lead Enricher (contact + opener) → your CRM / sequencer.
