Brex is a financial operations platform built for startups, mid-market companies, and enterprises. It combines corporate credit cards, business banking with cash yield, travel booking, and bill payment into a single system, with AI-assisted expense report automation and approval workflows. The platform layers spend controls directly onto its cards, letting finance teams set limits and policies before money moves rather than reconciling after the fact. Brex also offers ERP integrations, so transaction data can sync automatically with existing accounting systems for close and reporting.
Rho is a business banking platform that pairs FDIC-insured checking and savings accounts with corporate cards, bill pay, invoicing, and treasury management. Banking services run through a partner bank, while Rho's software layer adds spend controls, approval workflows, and automated accounting sync. Beyond day-to-day banking, Rho offers treasury products for idle cash, zero-fee bill pay and invoicing, and Delaware C-corp incorporation for new companies. The platform is aimed at startup finance teams, fractional CFOs, and accountants who want banking and spend tools in one place.
