Open-source community flywheel
Release your core product as open source to build trust and turn developer contributors into a self-sustaining acquisition engine.
Why this can grow a startup
Developers trust open-source tools more than proprietary ones, which lowers the barrier to adoption. GitHub stars and contributions act as social proof that compounds over time. Every project built with the tool becomes a public showcase. Community members answer support questions and create tutorials, reducing acquisition costs. Bottom-up adoption means individual developers bring the tool into their teams organically.
Company example
Supabase ($2B valuation, $398M raised) — open-source Postgres platform where GitHub stars, community contributions, and 'built with Supabase' project sharing drive bottom-up adoption from individual devs to enterprise teams.
