Aztec
About Aztec At Aztec we believe privacy isn’t just a fundamental right, but a creative force for web3. Our goal is to unleash the full potential of decentralized technologies by building an open, privacy-first network with no compromises. Privacy enables use cases that otherwise would not be possible and accelerates mainstream adoption. The next wave of web3 applications will require programmable privacy. Aztec’s technology empowers developers with the tools to build private applications and bring their ideas to reality.  Our journey started while building an application to bring syndicated loans on chain. We realized that our idea was a nonstarter without privacy. There were no solutions to offer privacy on public blockchains - so we sought out to build it ourselves. Since then, we've made industry-leading advances in cryptography, and deployed a private money platform and a private DeFi platform. To realize our vision of implementing privacy on a public blockchain, we are building a world-class team of cryptographers, engineers, and ecosystem builders. Supporting us on this journey are leading investors including Paradigm, Variant, Consensys, and a_capital.

Matter Labs
At Matter Labs, we are building zkSync : a blockchain scaling solution secured purely by cutting-edge cryptography. Our mission is to scale Ethereum to billions of users, fully preserving its most valuable properties — permissionlessness, trustlessness, and resilience — in order to protect and enhance global economic freedom. We hold a strong opinion that zero-knowledge proofs (ZKP) is the only technology today that can achieve this goal. We are also proud to be the pioneer of the ZKP tech on Ethereum, and one of the few companies in the world with strong expertise in this field. Our contributions over the last 3 years include the first ZK rollup ever built, the first implementation of recursive ZK proofs on Ethereum, and the world’s first practical FPGA-based ZKP accelerator. Most recently, we launched a zkEVM testnet , making zkSync the first ZK rollup capable of executing native Ethereum smart contracts. Across all hires we make at Matter Labs, regardless of role or team, we look for signals that a candidate will thrive in a culture like ours , where we value freedom, ownership mindset, and meritocracy.
