The DeepMind trio who built a poker AI are now making money for quant hedge funds

EquiLibre Technologies, a Prague-based AI lab founded by three ex-DeepMind researchers, applied the reinforcement learning tech that beat humans at poker to stock trading. It just raised a Series A led by Creandum at a valuation above $500 million. Creandum's VP called it the firm's largest single investment ever, though neither side disclosed the round size. The post does not disclose revenue or trading performance figures.

Why it matters: Ex-DeepMind researchers applying game-theory RL to quant funds at a $500M+ valuation is a fresh story. But the post lacks revenue or performance data, so information density is thin — right at the featured threshold.
