About Susumu Omori
Susumu Omori is a Japanese finance executive. A 2020 press release says he is the former head of Japan at Credit Suisse Securities and UBS Securities. Crunchbase describes him as a former Chairman of the Board of Directors of UBS Securities.
The same release lists his bio as starting in 1974 at Nomura Securities, followed by a move in 1990 to Credit Suisse First Boston. It also says he served as a member of the Tokyo Stock Exchange's Market Operations Committee.
Effective April 1, 2020, he became global strategic advisor to Cyber Security Cloud, Inc. In that role he advises on management and IR strategy for the company's global expansion and on corporate governance, including compliance. The sources I found do not show him founding a startup.
Crunchbase lists one personal investment for Susumu Omori, in MW. The dates and amounts on that page are hidden. The page does show a funding round for MW on June 11, 2026, with ALPHA and 10 other investors. I found no public statements from him about his angel investing approach, and no other angel investments.
The Lounge deals desk records one AI round for him: the MW seed round of $18.7M (JPY 3,000.0M) in June 2026. I could not confirm his individual check size. I also could not confirm what MW builds from the sources I found.
With one known investment, there is not enough public information to describe a stage, sector or geographic focus. The one known deal is a seed round. He has not publicly stated a check size or a set of investment criteria. His advisory work at Cyber Security Cloud suggests an interest in cybersecurity and global expansion, but he has not described this as an investing thesis.
