Fintech

Fin (fin.tech) is a crypto-native payments company that lets users and businesses move millions of dollars instantly — to other Fin users, directly into bank accounts, or across crypto rails. It provides business-grade payment rails that feel like a consumer payment app rather than crypto: instant global settlement in seconds, native support to deposit and withdraw to bank accounts, and send/receive of USDT, USDC, ETH, and BTC, while Fin abstracts the underlying crypto settlement behind a clean fintech interface. Backed by Sequoia, Multicoin, and Pantera Capital, Fin operates a private, auth-gated production API surface (api.fin.tech) and publishes an llms.txt for agents; it does not currently publish a public developer portal, OpenAPI, or SDKs. Surfaced in the API Evangelist network as a Pantera Capital portfolio company (sector: crypto) and enriched from its public web surface.

Fintech is profiled on the APIs.io network. Tagged areas include Company, Crypto, Payments, Stablecoins, and Banking.
