Hi, I'm Vlad. I work on protecting the Open Source infrastructure the world depends on.
I am the founder of the Software Stewardship Lab; a director of NYU's Software Supply Chain Security Operations Center; and a PhD researcher in the philosophy of Open Source at the University of Edinburgh.
I have helped raise $9.2 million for maintainers as part of the Open Source Pledge; have distributed $1 million to critical Open Source software on behalf of Sentry; have contributed to software used by the Gates Foundation to allocate $1 billion in healthcare funding; and created the regular expression engine for the Hare programming language.
I live in Edinburgh and also feel at home in Basel. I believe all people deserve respect, and I value collective governance over alienated wage labour. I celebrate playful, patient craftsmanship. I compose music, and I love cats and birds.
My last name is pronounced mir‑ih‑CHO‑yoo.

History
I was born in Bucharest, Romania, where I played ~5,000 hours of Pokémon. I started a software company when I was 18; we built stuff for the Gates Foundation, the University of Oxford, the Swiss Post and others.
I moved to Manchester, England to study computer science, then moved to Basel, Switzerland, which became the place that most feels like home. While in Basel, I continued to run my company and studied computational biology.
10 years into running my company, I decided to shut it down when I realised that the work was joyless, and that I had become an exploitative employer — uh oh! I had a lot of learning to do.
I moved back to the UK to research the ethics of work, with a focus on Open Source software, which became an ongoing PhD in philosophy at the University of Edinburgh.
In 2024, I started working on the Open Source Pledge, where I helped raise $9,200,672 for Open Source maintainers. This taught me a lot about serious issues in Open Source software: underfunding, precarious security, and maintainer burnout.
To work on these problems, I founded the Software Stewardship Lab, a non-profit applied research lab where we protect the world's Open Source infrastructure. Without this infrastructure, critical services like healthcare and transportation would break.
In my spare time, I do my very best to pet cats, play touching video games, and be kind. You can see some of my journey documented on the photos page.
I changed my name in 2026 — it used to be Vlad‑Stefan Harbuz.
