Founded in 2022 by Alex Fine, Fun develops backend payment infrastructure that enables platforms to move value between crypto tokens and fiat currency without routing users through exchanges or banks. The company integrates with a platform’s engineering team to build deposit and withdrawal rails and uses third-party providers to convert among tokens and currencies. Fun reports it processes more than $18 billion in yearly payments volume and serves over 20 clients, including Polymarket, Lighter, and Aave. The startup has a staff of almost 30 employees and declined to disclose revenue or profitability. Management plans to hire additional staff with proceeds from the Series A and to expand services to non-crypto-native companies as more firms add crypto payments.
