We build and backearly bets on people.
Big Brain Capital is where a small number of ideas get funded, built, and taken to market — patiently, in the open, one venture at a time.
We build, and we back.
Some ventures we start ourselves; others we back with capital and conviction. Either way it's a short list of names we believe in, held for the long run.
Build in the open
Transparent by default — clear terms, honest numbers, no hype.
Bet on people
Every venture comes down to backing the right person at the right moment.
Patient by design
Few bets, long horizons, real proof before we scale.
Building and backing.
