Starting an open source company: From project to platform

Field Guide

TL;DR

  • Open source success starts with adoption, not revenue.
  • The leap from project to company requires shifting from contributors to customers.
  • The best OSS founders are both engineers and evangelists.

Most great open source companies start the same way: one engineer scratching their own itch. But the transition from useful project to viable company requires a shift in mindset — from solving a problem to owning a category.

Is your idea right for open source?

Open source is most powerful when transparency, trust, or extensibility drive adoption — things like infrastructure, developer tools, data systems, or frameworks. If you’re building something developers will integrate deeply into their workflow, OSS gives you reach and credibility no marketing campaign could buy.

As one founder put it, “Open source is how you earn the right to sell.”

Three paths to OSS creation

  1. Spin out — A project born inside another organization that earns its own gravity.
    • Example: Apache Kafka → Confluent
  2. Inspired by — An open alternative to a proprietary solution.
    • Example: MongoDB reimagined Oracle for the developer era.
  3. Ground up — A novel approach to a problem no one’s solved before.
    • Example: HashiCorp with Terraform.

Each path demands conviction, patience, and community stewardship. And the best founders lead with humility — balancing idealism about openness with the pragmatism of building a business.
