One is where the money lives, one is how it moves
Mercury is the bank account a startup opens; Modern Treasury is the software layer that pushes payments across it and every other account a company holds. Two of fintech's quiet giants, solving opposite halves of the same problem.
Mercury Wants Your Runway, Novo Wants Your Workflow
Both fintechs offer fee-free business checking, but they are built for different moments. Mercury turns a startup's balance sheet into a finance stack; Novo helps an independent business turn daily work into organized cash flow.
Florin
Florin is a financial operating system for startups that brings banking, payments, cards, and treasury into a single account. Rather than reselling another bank's rails, the company is building the underlying infrastructure end to end, so money moves in real time on a single ledger it owns. Florin launched out of Y Combinator's Summer 2026 batch with an invite-only membership for venture-backed companies.
Rho
Rho is a New York-based financial technology company that bundles business banking, corporate cards, treasury, accounts payable automation, and expense management into a single fee-free platform. Built for startups, mid-market companies, and accounting firms, Rho positions itself as a 'financial operating system' that replaces the patchwork of legacy banks and disconnected finance tools that growing companies usually stitch together.
Every
Every is an all-in-one back-office platform for startup founders, bundling free incorporation, business banking, corporate cards, treasury, payroll, HR, benefits, bookkeeping, and taxes into a single dashboard. Founded in 2021 by Rajeev Behera and Barry Peterson and headquartered in San Francisco, the company raised a $22.5M Series A led by Redpoint Ventures in September 2024 to keep replacing the patchwork of tools that consume founders' time.
