Investment thesis
FOURSEAS aims to create new industries from Okinawa to drive growth across Japan and Asia. Through its 'Shinryo Fund' built on the 'Bankoku Shinryo (Cross-border)' concept, it leverages Okinawa's geographic position as a bridge between Japan and East Asia to make medium-term investments in promising seed-stage tech startups. Beyond capital, it supports entrepreneurs through its Koza Startup Arcade hub, the KOZAROCKS conference, coworking space, a startup studio providing software development, product design, back-office and fundraising support, and a broader startup support platform, fostering value creation that transcends regional and corporate boundaries.

4DI Ventures was co-founded by repeat tech operator and ESET Southern Africa founder Justin Stanford, giving it unusually deep cybersecurity and software operating experience rather than a purely financial background, and originated from Stanford's own angel-investing experiments that directly led to both the firm's creation and the launch of the Silicon Cape Initiative. The firm explicitly describes its style as "nurture capital" with intensive, hands-on engagement, and Stanford is vocal about avoiding the "unicorn at all costs" mentality in African tech, instead emphasizing sustainable market readiness and fundamentals in a more conservative, durability-focused investment approach.
