Making open source
prosperous for all.

Open source is the foundation of the modern economy. For it to keep compounding, it has to work for both sides: the people who use it, and the people who make it.

§ 02 · For Consumers · Safe To Use

The cybersecurity threat is expanding, fast.

Finding zero-days used to take elite, well-funded teams. Now frontier models find and exploit them autonomously, for anyone. Maintainers can’t absorb the flood, fixes don’t reach users fast enough, and secret embargoes no longer hold.

§ 03 · For Producers · Sustainable To Build

Open source has a funding problem. We have a plan to fix it.

Donations reach the few projects you can name, not the hundreds of packages beneath them. We want to route a fraction of commercial revenue back to the open source it was built on, so creators are rewarded as their work grows. The right incentives turn open source into a growing ecosystem of productive creativity.

  • 01Use it freely. No obligation below $1M revenue.
  • 02Share when you succeed. The upside flows back to the creators who made success possible.
  • 03Fund the whole graph. Every dependency gets its share; every fork inherits the clause.
  • 04Set the standard. Define what prosperous software means.
