James Dacombe became Europe's youngest self-made billionaire this month at 25, after the artificial intelligence chip company he started two years ago raised $312 million at a $3.3 billion valuation.
Olix tripled its valuation in six months from just over $1 billion. Fundomo, a New York investment firm, led the round. Arm, Hudson River Trading, Netflix co-founder Reed Hastings and the United Kingdom government's Sovereign AI fund all took part.
Dacombe owns about 30 percent of the London-based company, according to Forbes, which valued that holding close to $1 billion before counting anything else. He holds a further 12 percent of CoMind, the brain monitoring company he founded in 2017, which raised $102.5 million last August without disclosing a valuation and which he continues to run.
The valuation rests on a chip that does not exist yet. Olix expects to finish the design by the end of this year and deliver product in 2027. It employs more than 140 people across London, Bristol, Toronto and the United States.
Dacombe is betting against the architecture that made Nvidia the most valuable company in the world. He argues the industry is moving away from one general-purpose design serving every artificial intelligence workload and toward chips built for specific tasks, a thesis several better-capitalised challengers have tried and failed to prove.
The British government has named Olix among a group of domestic semiconductor companies it wants competing internationally, and set up a £500 million Sovereign AI Fund to back them.
He left school in 2017 to start CoMind and took a Thiel Fellowship four years later, the programme Peter Thiel funds to pay young founders to skip university. Its alumni include Ethereum creator Vitalik Buterin and Scale AI co-founder Lucy Guo.
Eleven self-made billionaires worldwide have yet to turn 30, and only four of them come from outside the United States. The next youngest in Europe is Arvid Lunnemark, 26, who left Sweden for MIT and co-founded the code editing company Cursor with three college friends in 2022. He and his co-founders each roughly doubled their fortunes to about $2.4 billion when SpaceX bought Cursor for $60 billion.
