KAST is redefining what it means to bank with stablecoins - think Revolut, rebuilt from scratch on Web3. Backed by top-tier VCs, we’ve grown from 0 to 1 million users in under a year. We’re building the next-gen global bank based entirely on stablecoins. Design is at the heart of everything we do - it’s how we simplify the complex, make money feel easy, and turn crypto skeptics into brand ambassadors. KAST is redefining stablecoin banking for global citizens, crypto professionals, Web3-native businesses, and high-inflation markets hungry for USD-backed banking. Backed by top-tier global investors and led by the ex-APAC CEO of Circle, our leadership team spans Circle, Airwallex, Revolut, Wise, Grab, Zoom, AWS, and leading OTC desks. We’ve scaled from zero to nearly a million users at ridiculous speed. By building directly onchain, we’ll deliver what traditional rails can’t: instant yield, flexible collateralized lending, and richer investment products. With a premium user focus and a culture built on velocity × excellence, we’re moving fast to outpace legacy players and build the next generation of financial services. Cards are how users experience stablecoins in the real world—paying at 100M+ merchants, withdrawing at ATMs, and accessing new forms of credit. Our ambition is clear: make KAST the #1 stablecoin bank globally.
