“Can a business banking platform for startups replace the fragmented stack of legacy bank account, corporate card, expense tool, AP software, and treasury management with a single unified financial OS?”
Founded in 2018 as a commercial banking platform for businesses, Rho positioned itself as an alternative to legacy banks by integrating banking, corporate cards, and accounts payable into a single platform. The company expanded from pure banking into treasury yield management (T-Bills, mutual funds via Apex Clearing), accounts payable automation, and most recently launched Rho Capital — a working capital line of credit for consumer and CPG brands. The strategic arc is clear: build the financial OS for startups and scale-ups by eliminating the need for separate banking, cards, expense, payables, and treasury tools.
