Demis Hassabis
Demis left Cambridge with a PhD and an idea for a world-class AI research lab at a time when UK investors wouldn't take the meeting. He flew to Silicon Valley instead, where one dinner unlocked the first few million from an investor who understood the long-term bet. Google acquired DeepMind for $650M in 2014; in 2024 Demis received the Nobel Prize in Chemistry for AlphaFold.
