# Paysend

> Paysend is a London-headquartered global fintech (founded 2017) running a cross-border digital payments network that moves money to bank accounts, cards, and wallets across 170+ countries in 40+ currencies. Paysend Enterprise exposes a single Payout API: one integration disburses funds worldwide to cards and accounts, with FX lookups, bank/card tokenization utilities, partner statements, balance queries, and webhook notifications.
