Mattias Ljungman co-founded Atomico with Niklas Zennstrom in 2006 and spent 13 years there as a General Partner, backing companies including Supercell, Klarna, Viagogo, and Climate Corp. He announced his departure in July 2019, remaining in a transition role for roughly six months, then founded Moonfire -- a London-based, AI-driven venture firm investing at pre-seed/seed stage -- out of a belief that Europe's seed ecosystem was "too fragmented, immature and definitely underfunded." Earlier in his career he worked at CLS Holdings, LEK Consulting, and Valu-Trac.
