Developers filter out traditional marketing. Here's what actually works — docs, DevRel, open source.
Marketing to developers is fundamentally different from marketing to any other buyer. Developers filter aggressively, distrust anything that feels like a sales pitch, and reward authenticity, technical depth, and genuine utility. Traditional marketing tactics (gated ebooks, cold email cadences, retargeting ads) not only fail — they actively harm brand perception. The tactics that work look nothing like traditional B2B marketing.
Best-in-class documentation (Stripe-quality docs are a moat, not marketing). Free tier that's actually useful (not "free" that's really a demo request). Open-source components (SDKs, integrations, sample apps under permissive licenses). Technical blog posts written by engineers (real code, real problems, real tradeoffs). Interactive sandboxes and playgrounds (no signup required to try). DevRel presence at conferences and on GitHub. In-product experience that respects developer time (short signup, no credit card for trial, honest error messages).
Gated content (developers won't fill out a form for a whitepaper). Cold outbound emails to engineering titles (get filtered as spam by dev tools). Retargeting ads following them around the web (perceived as creepy). Marketing-speak in docs ("leverage our synergistic platform"). Sales-first onboarding (booking a demo before letting them try). Vanity metrics without technical substance. Fake developer accounts on Hacker News or Reddit (community detects and punishes fast).
Developer Relations (DevRel) sits between product, marketing, and community. Great DevRel hires are working engineers who happen to be great communicators — not marketers who learned to code. Core DevRel activities: writing technical content, speaking at conferences, maintaining open source, running developer community (Discord/Slack), gathering product feedback from developers, and being the internal advocate for developer experience. Typical DevRel org: 1 per $5-15M ARR in developer-focused companies.
Open source strategies: (1) Open core (open-source foundation, commercial premium features — MongoDB, GitLab, Elastic). (2) Open source SDKs/integrations around a closed-source core (Stripe, Twilio). (3) Fully open source with paid managed service (Supabase, Vercel, Cal.com). Each has different economics. Open core works when the core is genuinely useful standalone. Managed service works when self-hosting is enough work that customers pay to avoid it. Both require 12-24 months of community-building before commercial pull happens.
Doc traffic + time on docs (quality proxy). GitHub stars + weekly active repos (community signal, not vanity). npm/PyPI/similar package downloads (usage signal). Signup-to-first-API-call conversion (activation proxy). Free-to-paid conversion (commercial signal). Community sentiment (Discord/Slack activity, Reddit mentions, HN posts). Developer NPS. Avoid measuring by MQL or SQL volume — the funnel doesn't map cleanly onto developer buying.
Hiring a marketer to lead DevRel (loses credibility with developers immediately). Gating everything (kills adoption). Bad docs (highest-leverage fix, most under-invested). Sales-first onboarding for developer products. No community presence (or worse, a corporate-feeling community where employees over-post). Cold outbound that mentions job titles like "Software Engineer" or "Head of Platform."
