Arthur Keller

Arthur Keller is a five-time founder with two successful exits, renowned for building his entire career outside traditional corporate structures. Throughout his journey, he has exclusively founded and led his own companies, transforming contrarian thinking into a consistent competitive edge across industries—from fintech to creative production and global commerce.

Arthur's entrepreneurial path includes founding and exiting a production company specializing in high-end content, as well as a tequila brand, which he successfully sold after prevailing in a complex U.S. federal court case. Today, as Founder & CEO of London-based Ross & Andersen LLP, he delivers global financial solutions to independent professionals and small businesses, earning approved vendor status with Fortune 500 leaders such as LVMH, Kering, Amazon, and Universal. Through his Hong Kong consulting firm, Vantage Partners Limited, Arthur accelerates growth in the luxury and sports sectors, providing bespoke strategies to optimize performance and drive sustainable expansion in the global marketplace.

A former top-50 Olympic-class sailor, Arthur brings elite discipline and an execution-focused mindset to every venture. This is complemented by a creative vision honed in New York City's creative industry while working for the world's biggest fashion brand. Arthur's global perspective—shaped by experiences across Europe, Asia, and a decade in the U.S.—now drives his most ambitious project: Privium, the American neobank for global citizens, designed for a truly borderless world.
