Today, the company serves close to 400 credit unions, thousands of employees and millions of members. Headquartered in Ogden, UT and Coral Gables, FL, Blossom is on a mission to build the first intelligent banking system that puts credit unions at the center of their members' financial lives, helping local communities thrive and transforming the way people experience money.
