Investing in Early Stage Tech Founders.
Builder Capital backs founders building at the forefront of cryptography, robotics, photonics, AI, and advanced manufacturing.
Hard problems. Real technology.
Every era of progress is defined by a handful of technological breakthroughs.
Electricity. Flight. Semiconductors. The internet.
We think the next generation will emerge from advances in computation, photonics, robotics, and energy.
The hardest problems create the most enduring companies.
We invest in scientists and engineers turning breakthrough ideas into real systems — new machines, new industries, and new infrastructure. We back the people building the future.
