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.
