About mrFusion
mrFusion is a fusion energy startup based in Odense, founded in 2025.
We believe that fusion energy is the ultimate energy source.
We apply first principles in the design of our solution, and our working style is experimental and guided by agile methods.
We are looking for partners and potentially co‑founders – both on the technical side and within business development.
I hope you find this exciting. Feel free to write to me, and let’s have a conversation.
