It unifies core banking, digital banking, card issuing and processing, payments and branch automation in one open, modular, developer-first platform, designed for both humans and AI agents. Most credit unions run on a patchwork of outdated systems. Blossom replaces it one vendor at a time, so they can modernize gradually and end up on a single intelligent platform that evolves with them. Blossom was founded in 2020, acquired HomeCU that same year, launched its digital banking platform in 2023 and acquired CUProdigy in 2024 to bring every customer onto its new core. As a CUSO, it has raised over $47M from credit unions. Today, it serves more than 350 institutions with millions of members.
