Libro looks like a bank. It acts somewhat like a bank. But it isn't a bank. It's a credit union. And what is a credit union? It is a member-owned, cooperative financial institution. Like a bank, a credit union accepts deposits, makes loans and provide a wide array of other financial services. Unlike a bank, a credit union is an not-for-profit organization that exists to serve its members -- or that's the theory. The reality can be a bit more complex.
What I find most interesting about credit unions is the cooperative angle. We tend to think of capitalism as the only game in town. But, it isn't. Globally, cooperatives leave a huge footprint on our world. Credit unions are but a small part of that footprint.
