Category Labs (formerly known as Monad Labs) is a team of systems engineers and researchers on a mission to design and build at the frontier of decentralized technology. We strive to design and build step-function improvements over existing blockchain solutions. After raising $225M in series A funding, led by Paradigm, we are growing our team.
We’re the team behind Monad, a high-performance, EVM-compatible Layer 1 whose public mainnet is now live. We write the core software that runs it: a parallel-execution EVM, a custom state database, and a BFT consensus client, all developed in the open.
A note on hiring: Recruiting outreach from Category Labs will always come from a @category.xyz email address. We currently don't work with external or third-party recruiters, so anyone claiming to recruit for Category Labs from another company isn't legitimate. If someone reaches out about a role, check their email address and confirm the role on our Careers Page: www.category.xyz/category-careers. Please report anything suspicious to [email protected].
