Biography

細谷 裕一 is listed as a キャピタリスト (capitalist) on the MITSUI SUMITOMO INSURANCE Venture Capital capitalist page, which is the firm's published investment roster. The firm's own profile of him or her reads, verbatim: 「大学卒業後、KDDIに入社。CVC部門にてベンチャー投資に関わり、ファンド運営・協業推進、投資先支援等を経験。2018年12月当社に入社。」 The same page publishes a 主な担当先 list of the portfolio companies he or she is responsible for, which is the basis of the notableInvestments recorded here; entries the firm tags IPO or SOLD on that page are past outcomes rather than statements of a current shareholding. The firm's 9 January 2026 interview article about portfolio company 株式会社APTO identifies him as 三井住友海上キャピタル株式会社 投資部 マネージャー and states that MSIVC has invested in APTO as lead investor in every round since 2020.
