About Griffin Hi, we’re Griffin! We’re the bank for companies who want to build and launch financial products. Our context We're rapidly heading towards a future where most of us access financial services through technology companies rather than high street banks. All sorts of companies are now embedding financial products into their apps and user journeys so that their customers can seamlessly make payments, manage expenses, take out loans, save, invest, and do more. The problem is that companies are still dependent on legacy banking infrastructure if they want to offer regulated financial products. They need to either partner directly with an incumbent bank and/or stitch together middleware from various Banking as a Service (BaaS) providers. This process is slow, expensive, and complex and makes it very hard for companies to get new financial products off the ground. At Griffin, we want to change this. Our purpose We want to make it easy for companies to bring finance to their customers at the point of greatest relevance. So, we built a bank. But not just any bank! Griffin is a technology platform and a bank: fully regulated, API-first, developer-centric, and purpose-built to serve innovative fintechs and brands who want to build and embed financial products. Learn More About What We Do. Our culture Our culture is our most important asset, and one of the ways we safeguard it is by being extremely intentional about hiring the right people. We won't hire people who don’t seem like a strong fit for our core values, even if they're otherwise extremely qualified.
