Bio

A former data scientist with an MSc in Machine Learning, Barney Hussey-Yeo launched Cleo from his bedroom in 2016 with a single conviction: the next generation wouldn’t be disconnected from their money, they’d be in conversation with it.

A decade on, that bet has scaled into an AI financial assistant that has helped millions of people, surpassed $300 million in ARR, and grown to a 500+ person team across London, New York, and San Francisco.
