Manifesto

Open source runs the world. Who's keeping it alive?

Your phone, your bank, your streaming service, the router in your office: they all run on open source code maintained by people who get paid next to nothing. I know because I was one of them. Simbiosi.org is where I dig into why this keeps happening and what we can do about it.

1/3 of open source maintainers get zero compensation
~3 people or fewer maintain most critical projects
9 yrs I maintained Remmina for 150k users - about 1000 CHF/year in donations
€17M Germany's Sovereign Tech Fund in 2025, up from €3.5M in 2022

The problem isn't technical

It's about psychology and incentives. The free rider effect. The bystander problem. Invisible infrastructure that everyone depends on and nobody thinks about. Companies worth billions build their products on code maintained with the budget of a small NGO. The maintainers burn out, and nobody notices until something breaks.

I lived this for 9 years. I maintained Remmina, a remote desktop client used by over 150,000 people. 8,000+ commits from 200+ contributors, CI/CD pipelines, issue triage, code reviews, releases. The donations I received: about 1,000 CHF per year. That's roughly 110 CHF per month for what was basically a second job.

What I do here

I look at how open source projects ask for money, why donation psychology works against them, and what actually changes the numbers. Real data, real projects, real analysis.

  • Case studies - I pick a project, go through the finances, the messaging, the donor data, and figure out what's working and what's not
  • Behavioral analysis - Why people don't donate to open source even when they depend on it every day
  • Resources for maintainers - What I've learned over 9 years and what I keep learning from others

The name

Simbiosi: symbiosis. Two organisms living together, both benefiting. That's what open source should be: companies and communities sustaining each other. Not extraction. Not charity. Mutual benefit.
