Frequently asked questions

How does Soraseed differ from a traditional Japanese venture capital firm?

Soraseed operates as a startup studio rather than a conventional VC. The firm generates its own business concepts and recruits entrepreneurial teams to co-found and operate the resulting companies. This model gives Soraseed founder-level equity stakes and deep operational involvement, in contrast to the passive minority positions typical in Japanese venture capital.

Who makes investment and incubation decisions at Soraseed?

Co-founders Kazumasa Ozawa and Masataka Matsumoto lead investment decisions. Both partners are involved in selecting ventures for the studio pipeline and actively participate in building the early-stage companies that enter the portfolio.

What sectors does Soraseed target?

The studio focuses on B2B enterprise software, fintech, digital health, and applied AI. Portfolio companies tend to serve enterprise customers in Japan and across Southeast Asia, with business models centered on SaaS, marketplace platforms, and data-driven services.
