HIFI Tech Stack

Developer infrastructure for programmable money movement across fiat and crypto

Financial Services New York, NY 11–50 employees Founded 2022 Privately Held

HIFI operates a payments infrastructure platform built on Go, Python, Node.js, and PostgreSQL, with integrations to Visa Direct and SWIFT on the fiat side and Ethereum Virtual Machine + USDC on the stablecoin side. The 19-person team is weighted toward engineering (7) and product (4), with active hiring across both disciplines — a signal they're scaling API and SDK delivery faster than sales. Current focus spans real-time money movement APIs, transaction monitoring systems, and a stablecoin-powered debit card program, while internal friction around AML process automation and transaction reliability at scale suggests the reliability layer is still being hardened.
