Ryuichi Onose (29) Japan

Together with bioengineer Takao Yasui, Onose founded Craif in 2018 to focus on early cancer detection. The Tokyo-based startup will check for cancers, including lung and ovarian, at its lab by using AI to analyze urine samples collected by its own proprietary device. Its point of differentiation: it can extract more biomarker data than others in the industry. Craif, which raised $7.5 million in funding so far, aims to launch the testing service next year. Eventually the firm hopes to broaden the range of illnesses screened, offer the best treatment options and expand in Japan and overseas.
