Japan Angel Investors Association / Angel Link

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.
