Catena Labs is building the first AI-native financial institution to provide the new financial infrastructure and services AI systems need to conduct commerce. We’re giving AI agents the tools to identify themselves and use money safely and efficiently. At the same time, we’re providing businesses with a trusted, licensed financial partner with the capability to manage risk and compliance. By building a financial institution with AI and stablecoin infrastructure, we are breaking down the legacy financial system barriers that prevent an AI-driven economy.

Backed by leading venture investors, we’re assembling a team of engineers, designers, data scientists, and finance professionals working together to build a stronger, more resilient global economy that creates broad prosperity. We’re looking for people with the talent, curiosity, and passion to invent an entirely new category of financial services.
