Aztec Labs
Aztec, founded in 2017 by Zac Williamson and Joe Andrews in London, builds privacy-focused zero-knowledge infrastructure on Ethereum. Its stack includes Noir, a DSL for writing ZK circuits, the Aztec Connect privacy layer, and Aztec Network, an encrypted ZK-rollup that enables private smart contracts with selective disclosure using PLONK proofs. The project handles private state and compliance views without revealing user data on-chain, targeting DeFi and identity use cases. Headquartered in London with teams across the UK, EU and US, Aztec is backed by leading investors and collaborates with academic cryptography groups. It advances programmable privacy as open research and product. Expect a research-intensive culture that values cryptographic rigor, careful audit practices and building usable privacy primitives that respect both confidentiality and accountability.
