This looks really cool, but can someone help me understand more about where it fits in the market? Is this for me, as a developer to just make my own bank accounts? Does this allow me to create a bank frontend SaaS and use column as the backend? Can I originate loans with this platform for myself, or maybe to others somehow? tl;dr Who is the customer?
