Company

Aydin Sorensen is listed as a founder of Florin. Florin brings banking, payments, cards, and treasury into one account built for startups - so founders can hold, move, and grow their capital without stitching together half a dozen tools. Unlike platforms that resell another bank's rails, we're building the infrastructure ourselves, end to end, so money moves in real time on a single ledger we own. We start with an invite-only membership for venture-backed companies and expand from there. Named after the florin, the coin that anchored global trade for three centuries, with infrastructure built for how money moves now.
