Kast has launched KAST Business, a stablecoin-based platform that offers enterprises business accounts, payment cards, cross-border transfers and wealth management services. The product allows companies to open fiat virtual accounts through partnered licensed institutions, receive payments, deposit supported stablecoins and crypto assets, issue virtual cards and make local payments in more than 20 fiat currencies. The platform offers up to 8% annualized yield on idle funds, sourced from short-term U.S. Treasury bonds and stablecoin yields, along with up to 3% cashback on spending. Kast previously raised $80 million at an approximately $600 million valuation and said it plans to use the funding to expand into North America, Latin America and the Middle East. The company says it has more than 1 million users and is targeting 1,000 to 5,000 active enterprise clients by the end of 2026.
