Saeju provides the core of the Noom spirit and drive. His entrepreneurial journey started at age 19 in Korea, when he established BuyHard Productions, an independent music label chosen as the most promising e-business in Korea in 2001. After early success in Asia, his ambition led him to global markets and New York, where he was the sole representative of an international music company. Saeju was able to build the team for the Asian tour of the Broadway musical "Bye Bye Birdie," without knowing anyone beforehand.

Despite his other interests, Saeju has always pursued technology, studying Electrical Engineering at Hong Ik University, working as an IT specialist in the Korean defense industry for 3 years, and completing a variety of IT certifications. At Noom, Saeju contributes his integrity and passion to the team, investors, partners, and users. Saeju is always the loudest guy at the lunch table, cheering on the team's daily accomplishment and celebrating progress. He truly believes Noom's diverse culture is the reason it has succeeded globally.
