Repo to Revenue: How Side Projects Become Income Streams

The Third Path

For years, developers with a great idea have faced a binary choice: open-source the project and give it away, or try to build a full startup around it. Both paths have significant friction. Open-source gives you community and credibility, but rarely pays the bills. Startups require fundraising, hiring, and a complete shift from building to managing.

We believe there should be a third path. One where you can keep building the things you care about and get paid for the value they create. Not through ads, sponsorships, or donations, but through straightforward commercial distribution.

How It Works

The concept is simple: you build an AI agent, a workflow, a tool, or any useful piece of automation. You publish it to the Kainotomic marketplace. When someone uses it, you earn. The pricing is up to you. The terms are transparent. We handle the distribution, billing, and integration layer so you can focus on what you do best.

We've seen developers build incredibly useful tools during a single weekend hackathon. A Slack bot that summarizes long threads. A CLI tool that auto-generates test cases. A document parser that extracts structured data from messy PDFs. Each of these solves a real problem, and each of them should be generating revenue for its creator.

Beyond the Marketplace

Repo to Revenue is more than a marketplace feature. It's a philosophy about how the software industry should work. The people creating the most value at the edges of the ecosystem should capture a proportional share of that value. Full stop.

We're building the infrastructure to make that happen. If you've ever built something useful and wished there was a simple way to earn from it without becoming a full-time CEO, that's exactly what we're here for.
