OMB Bank is a Southwest Missouri community bank that has pivoted sharply into Banking-as-a-Service. In March 2024 it joined the Treasury Prime bank network — Treasury Prime called it the firm's fastest bank implementation to date. In February 2025 OMB formalized this strategy by launching OMBX, a dedicated embedded finance division with its own brand and website, led by chief innovation officer Steve Bishop. OMBX is positioning OMB as a sponsor bank for fintech programs, already supporting partners like LeafLink / Dama Financial's cannabis-industry banking stack.
