Marvin (Marvin Tecnologia Ltda., CNPJ 41.240.161/0001-30) is a São Paulo, Brazil based B2B fintech and tech-native collateral agent that transforms credit-card and duplicata receivables into registered financial guarantees. Born out of Brazilian Central Bank Resolution 264 — which legalized the negotiation of credit-card receivables as financial assets — Marvin operates a "registration-as-a-service" platform that lets retailers, banks and suppliers register, manage and settle receivables-backed collateral, unlocking working capital for merchants. The company is backed by a US$15M Series A led by Canaan Partners (with Canary and Maúa Capital) and works with partners including B3, C6 Bank, Casas Bahia, Electrolux, Pernambucanas and AVLA. Marvin runs a private backend (app.marvin.com.br) for its customers; it does not currently publish a public developer API, documentation, or SDKs. This profile was added to the API Evangelist network as a Canaan Partners portfolio lead and enriched from public web sources.
