If you're a SaaS founder building for developers, you have a distribution advantage that most B2B founders don't: your customers live on GitHub. They post their problems in Issues. They evaluate tools by starring repos. They write code that reveals their stack. The challenge is not that developer leads are hard to find — it's that most founders aren't set up to capture the signals when they fire.
The Developer Buying Journey Starts on GitHub
Enterprise buyers research on G2, Gartner, and vendor websites. Developers research on GitHub. When a developer needs a logging library, they search GitHub. When they're evaluating observability tools, they star repos. When they hit a problem your product solves, they open a GitHub Issue describing it. These are buying signals — often more accurate than any intent data vendor because they're behavioral and specific.
The problem is that GitHub signals are ephemeral. A star happens, a repo gets a new contributor, an issue is opened — and unless you're watching, you miss it. Most founders do one of two things: nothing (miss the signal entirely) or manual scraping (unsustainable at scale). There's a better way.
Signal Type 1: Your Own Repo's Stargazers
If your product has an open-source component, a CLI, an SDK, or any public GitHub presence, every new star is a warm lead. Stargazers have self-identified as interested in what you do. The question is: who are they, and how do you reach them?
The GitHub API exposes stargazers with timestamps, so you can get not just who starred but when. Combined with the user's public profile — bio, company, top languages, email if listed — you have enough context to write a genuinely personalized outreach email in under 2 minutes.
- New stars on your SDK or CLI repo → founders and engineers evaluating your developer tool
- New stars on your documentation site repo → developers in active research mode
- New forks of your template or example project → developers who are trying to implement what you do
- New watchers on your main repo → developers tracking your release cadence (high intent)
Signal Type 2: Competitor Repo Stargazers
This is one of the highest-leverage moves available to early-stage founders: monitor the repos of your main competitors and capture everyone who stars them. These are developers who are actively evaluating your category right now. They haven't chosen a vendor yet. They are your warmest possible cold leads.
You can monitor multiple competitor repos simultaneously. A developer who stars both Competitor A and Competitor B is clearly in active evaluation mode and should be prioritized for outreach. Signal stacking — a developer showing multiple signals across related repos — is a strong indicator of near-term purchase intent.
Signal Type 3: Keyword Mentions in GitHub Issues and PRs
This is the most underused signal in developer GTM. Developers describe their problems in GitHub Issues before they search for solutions. If you monitor the right keywords, you can find developers actively dealing with the problem your product solves — before they've started evaluating vendors.
For example: if you build a database connection pooling tool, monitoring GitHub for "too many connections", "connection pool exhausted", or "pgbouncer alternative" will surface developers with the exact problem you solve. The same works for any category.
Examples of keyword signals to monitor by category:
Observability tools: "tracing overhead", "otel alternative", "distributed tracing slow"
Auth tools: "JWT token rotation", "session management pain", "auth middleware"
API tools: "rate limit handling", "api gateway config", "openapi spec"
Data pipeline: "etl bottleneck", "kafka consumer lag", "dbt model slow"
Security tools: "dependency vulnerability", "supply chain attack", "SBOM"Signal Type 4: Stars on Adjacent / Complementary Repos
Even if a developer doesn't star your exact category, they may star tools in the same ecosystem. If you build an observability layer for Kubernetes, developers starring the Kubernetes, Prometheus, and Grafana repos are your ICP. Set up monitoring across the ecosystem, not just direct competitors.
The Founder's Manual Workflow (0 to First Pipeline)
- List the 3-5 GitHub repos most relevant to your ICP: your own repo, top 2 competitors, top 1-2 ecosystem tools
- Check stargazers weekly via the GitHub API or GitLeads — filter for developers with public emails or company names matching your ICP
- Write 3-sentence emails referencing the specific repo they starred and the one problem you solve for that use case
- Send manually the first time. Track replies and iterate on messaging before automating anything
- Once you have a message that converts >10%, automate: use GitLeads to push stargazers directly into Smartlead or Instantly campaigns
When to Automate (and When Not To)
Manual outreach is faster to learn from but doesn't scale. Automated outreach scales but you need to get the messaging right first. The founder mistake is to automate too early — running automated sequences with templates that don't convert wastes leads and damages your domain reputation.
Automate when: you have at least 10 replies from manual outreach and understand what message works. Automate by pushing GitLeads captures directly into an email tool like Smartlead or Instantly. Keep personalization tokens tied to the specific GitHub signal — repo name, keyword matched, and the specific problem it signals.
Founder Mistakes to Avoid
- Monitoring repos and never reaching out — signals expire, developers move on
- Sending identical templates to every lead — developers see through it immediately
- Pitching pricing in the first email — lead with the problem you solve, not how much it costs
- Over-following up — one follow-up maximum; respect the developer's inbox
- Ignoring leads without public emails — many are reachable via their company domain, GitHub username on LinkedIn, or community channels
- Waiting until you have "enough data" — start with 10 manual outreach attempts this week
Tools for the Stack
- GitLeads — monitor GitHub repos and keywords, push enriched leads to your outreach stack automatically
- Smartlead or Instantly — email infrastructure with high deliverability for cold outreach
- Clay — enrich leads with additional data (LinkedIn, company size, funding) before outreach
- HubSpot free — CRM to track conversations and prevent duplicate outreach
- n8n or Make — automation layer if you need custom routing between tools
