Investment thesis

FQV Fond I Doo is the fund vehicle for FifthQuarter.vc, a seed-stage investor targeting the Western Balkans, particularly Serbia and Croatia. Its thesis pairs technical deep tech teams from the region with commercially oriented cofounders who know North American and Western European markets; three AI companies matching this pattern are in Fund I. The fund has two GPs with dual-geography coverage: Pedja Predin, who has a finance, VC, and unicorn operating background and splits time between Serbia and Croatia, and Tihomir, a repeat technical cofounder.

4Di Capital

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.
