Irreducible

Irreducible is a cryptography company that invented and developed Binius, a zero-knowledge proof (ZKP) system designed to natively handle bitwise operations for faster, more cost-efficient proof generation. Founded in 2022 as a cryptographic hardware company, Irreducible built infrastructure aimed at accelerating zero-knowledge proving for web3 networks and blockchain infrastructure, with a stated mission to bring reliable, cost-efficient proof generation to the crypto industry. The company raised a $24 million Series A co-led by Paradigm in January 2025, following earlier seed funding co-led by Bain Capital Crypto and Paradigm with participation from Jump Crypto. Irreducible was headquartered in San Francisco, California. In late 2025 the company's founders announced they were winding down operations.
