Marketing Lead, KAST Business

KAST is redefining stablecoin banking for global citizens, crypto professionals, Web3-native businesses, and high-inflation markets that want USD-backed banking. Backed by top-tier global investors and led by the former APAC CEO of Circle, our leadership team spans Circle, Airwallex, Revolut, Wise, Grab, Zoom, AWS, and leading OTC desks. We scaled from zero to nearly a million users at speed.

One account lets a business hold USD and stablecoins, spend on cards worldwide, and pay contractors and vendors in 170+ countries over local rails, SWIFT, SEPA, and stablecoins. Businesses incorporated in the US, UK, UAE, Brazil, and Australia onboard under one program.

We came out of beta in August. Monthly card volume is up more than 10x since then, and hundreds of active businesses run on KAST Business today. Our fastest-growing customers are performance marketers: agencies, media buyers, and e-commerce brands funding ad spend across Meta, Google, and TikTok.
