Kokuei Yuan (also known as 'Guo' to his associates) is a Japanese billionaire businessman and the co-founder of the Bullish crypto exchange. He is highly educated, having studied economics and studio art at Tufts University.

Yuan’s early career was spent in the traditional financial centers of Asia, where he served as an investment banker at CLSA. This background in institutional finance eventually informed his pivot toward the emerging digital asset class in 2016.

Kokuei Yuan's career is defined by his executive partnership with Brendan Blumer. He served as the Executive Chairman of Block.one, the firm that developed the EOS.IO blockchain platform, which famously raised over $4 billion in its Initial Coin Offering (ICO).

His structural achievement is tied to the founding and scaling of Bullish, a regulated crypto exchange launched in 2020 with backing from Peter Thiel and Mike Novogratz. He successfully navigated the company through its public listing on the New York Stock Exchange in August 2025, a debut that established him as a billionaire with a 25% stake in the company.
