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.

Cryptographic Systems

The future of finance is moving on-chain. Real world assets and stablecoins require immutable, permissionless rails that operate 24/7 with instant settlement. We believe that blockchain will be the technology to facilitate this. With quantum becoming more of a reality each passing year, the innovation of new encryption schemes becomes more and more important. We predict that technologies such as zero knowledge and fully homomorphic encryption will be at the forefront of this movement.
