When we built Stripe, one of the largest points of friction was getting a banking partner. It took months and only after signing were we even able to start assessing the technology. There are so many potential companies that simply don't make it past the partnership step. We want to fix that.
The US needs a bank (holding a bank charter) that's also a technology company. Increase certainly isn't there yet (patches welcome: jobs@increase.com) but we already have integrations with the Federal Reserve, Visa, and The Clearing House. Our API already serves businesses you know and love.
