Analysis
Flourish raised $500 million at a $2.5 billion valuation to pursue brain-inspired AI, with Jeff Bezos writing one of the biggest checks -- initially around $50 million before nearly doubling to roughly $100 million. Lux Capital, GV and Catalio Capital also backed the round, which came together in about five weeks after discussions began in late April.
The company is building what it calls Cortex AI, a system designed to emulate brain function by mapping real neurons and their connections -- the field of connectomics. The headline ambition is efficiency: Flourish targets inference in the 20-to-50-watt range, roughly a laptop's draw rather than a server rack's, a direct assault on the energy economics that increasingly constrain AI's expansion.

The founding team gives the moonshot weight. Thomas Reardon created Internet Explorer at Microsoft and later founded the brain-computer-interface company CTRL-labs, which Meta acquired in 2019 for an estimated $1 billion; co-founder Rob Williams is a former Amazon S-team executive. It's a contrarian bet that the next leap in AI comes from rethinking the substrate, not just scaling the current one.
