About KAST
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.
At KAST, we’re redefining stablecoin banking for global citizens, crypto professionals, web3 businesses, and high-inflation markets. Backed by top-tier VCs and led by the ex-APAC GM of Circle, we’ve scaled from zero to nearly a million users in record time.
