Rain is an enterprise stablecoin payments platform that lets companies embed digital-dollar money movement into their products through a single API. Its infrastructure spans stablecoin wallets and virtual accounts, card issuing (Rain is a Visa and Mastercard Principal Member, settling Visa card transactions daily in stablecoins across multiple blockchains), and money movement via fiat on-ramps, off-ramps, and cross-border payment orchestration. Rain abstracts the back-end complexity of making on-chain stablecoins interoperable with traditional card networks, and maintains PCI DSS and SOC 2 compliance. Customers include Western Union, Nuvei, and ether.fi. Rain has raised over $338M, including a $250M Series C led by ICONIQ and a Series B led by Sapphire Ventures.
