About us

We are Resistant AI, a fast-moving startup where things happen quickly, and decisions are made just as fast. We believe in taking initiative – better to ask forgiveness than permission – but don't worry, we keep it organized and collaborative. If you love the thrill of building and iterating, you'll fit right in! 👌

And what do we actually do?

We protect the AI and automation systems of modern financial services from manipulation and attack. We do so by forensically analyzing everything from the documents submitted by customers to the ongoing behaviors they exhibit while using the service to uncover and prevent serial fraud, synthetic identities, account takeovers, money laundering and as yet unknown financial threats operating at scale.

This is our founding team's second startup, and we recently closed our Series B investment round led by Google Ventures, Index Ventures and Credo Ventures.
