We are building an AI-first global consumer neobank. This means two things:

1. Rebuilding the entire financial stack from scratch: checking accounts, peer-to-peer payments, credit cards, and investment products.
2. Using AI to both run the complex operations behind the scenes, and give consumers products and tools that they could not get from any other financial institution today.

We are a small, senior-only team in San Francisco. We’re repeat founders who have worked together before, and builders of products serving hundreds of millions of people and generating billions in revenue at companies like Robinhood, Plaid, Chime, Brex, and Stake.

We believe that people are now far more capable of full-stack problem ownership than ever before. Every person on the team is maximally empowered to ship product and shape the direction of the company.
