Push GitHub Leads to Klaviyo — Developer Signal Enrichment

Klaviyo is the go-to email and SMS marketing platform for product-led growth teams. If you sell developer tools, your best leads are already on GitHub — starring repos, opening issues, and mentioning competitors in discussions. GitLeads captures these signals in real time and routes enriched developer profiles to Klaviyo so you can trigger targeted flows the moment buying intent appears.

Why Route GitHub Signals to Klaviyo?

Klaviyo's strength is behavioral segmentation and flow automation. When you combine it with GitHub intent signals, you can trigger flows based on actual developer behavior — not just page views or form fills. A developer who stars your competitor's repo and has 500+ followers is a fundamentally different lead than someone who clicked a Google ad.

• Trigger Klaviyo flows the moment a developer stars a tracked repo
• Segment by language stack, company size, follower count, and bio keywords
• Personalize messaging based on signal type (stargazer vs. keyword mention)
• Build developer nurture sequences tied to GitHub activity, not arbitrary timers

What GitLeads Captures from GitHub

GitLeads monitors two signal categories. Stargazer signals fire when a developer stars a repo you track — including competitor repos. Keyword signals fire when your target keywords appear in GitHub Issues, PRs, Discussions, commit messages, or code comments. For each signal, GitLeads enriches the lead with: name, email (when public), GitHub username, bio, company, location, follower count, top programming languages, and the raw signal context.

Setting Up the GitLeads → Klaviyo Integration

GitLeads connects to Klaviyo via webhook or native integration. For each signal, GitLeads POSTs enriched lead data to your Klaviyo list or segment, creating or updating the profile automatically.

// GitLeads webhook payload → Klaviyo profile upsert
const signal = {
  signal_type: 'stargazer',
  repo: 'competitor/dev-tool',
  lead: {
    github_username: 'devlead42',
    email: 'dev@example.com',
    name: 'Jane Developer',
    company: 'Acme Corp',
    location: 'San Francisco, CA',
    followers: 847,
    top_languages: ['TypeScript', 'Go', 'Python'],
    bio: 'Senior SWE @ Acme. Building developer tools.',
  },
};

await fetch('https://a.klaviyo.com/api/profiles/', {
  method: 'POST',
  headers: {
    'Authorization': `Klaviyo-API-Key ${process.env.KLAVIYO_PRIVATE_KEY}`,
    'Content-Type': 'application/json',
    'revision': '2024-02-15',
  },
  body: JSON.stringify({
    data: {
      type: 'profile',
      attributes: {
        email: signal.lead.email,
        external_id: signal.lead.github_username,
        first_name: signal.lead.name.split(' ')[0],
        last_name: signal.lead.name.split(' ').slice(1).join(' '),
        properties: {
          github_username: signal.lead.github_username,
          github_company: signal.lead.company,
          github_followers: signal.lead.followers,
          github_top_languages: signal.lead.top_languages.join(', '),
          github_bio: signal.lead.bio,
          github_signal_type: signal.signal_type,
          github_signal_repo: signal.repo,
        },
      },
    },
  }),
});

Klaviyo Flows to Build with GitHub Signals

1. Competitor stargazer flow: trigger on signal_type = "stargazer" from a competitor repo, send a differentiation email within 30 minutes
2. Keyword intent flow: trigger when a lead mentions your product category in a GitHub Issue, send a use-case-specific sequence
3. High-follower VIP track: branch on github_followers > 500 to route influential developers to priority outreach
4. Language-specific onboarding: branch on github_top_languages to send Go vs. Python vs. TypeScript tailored content

Native Integration vs. Webhook

GitLeads offers a native Klaviyo integration that handles profile creation, list assignment, and event firing automatically. Alternatively, use GitLeads' webhook output to build a custom integration via n8n, Zapier, or a serverless function — giving you full control over list segmentation logic.
