Florin

Florin is a San Francisco fintech startup building an integrated financial operating system for venture-backed companies. Rather than reselling another bank's infrastructure, Florin is building the underlying money-movement rails end to end so that funds settle in real time on a single ledger the company owns. The product combines business accounts, cards, payments, and treasury management into one invite-only membership aimed at startup founders who would otherwise stitch together half a dozen separate tools to hold, move, and grow their capital. Florin was founded in 2026 by Shaurya Aggarwal (CEO), Amol Pant (CTO), and Aydin Sorensen, and is a member of Y Combinator's Summer 2026 batch. At the time of this profile Florin operates a single marketing landing page with a waitlist and publishes no public API, developer documentation, or other developer-facing surface yet; this entry captures the company's identity and awaits a public API to enrich further.

Florin is profiled on the APIs.io network. Tagged areas include Company, Fintech, Banking as a Service, Neobank, and Payments.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
