BigBang Angels

Sung-wook Hwang, co-founder and CEO & Managing Partner, leads the investment committee. The firm leans on his network across Japanese corporate venture groups and Korean startup founders, built since BigBang Angels' founding in 2012.

The firm sources primarily through its deep integration into the Seoul early-stage ecosystem and its cross-border demo-day circuit between Korea and Japan. BigBang Angels acts as a first-call partner for Korean founders seeking Japanese market entry, which generates proprietary deal flow that generalist seed funds do not see.

BigBang Angels invests in startups based in South Korea with the intent and capability to commercialize in Japan and, more recently, Southeast Asia. This is a deliberate corridor strategy rather than a pan-Asian mandate — the firm concentrates on the Seoul origination to Tokyo distribution pipeline, with a growing secondary focus on Southeast Asian scale markets.

The firm does not publicly list excluded sectors, but its portfolio pattern shows minimal exposure to consumer social platforms, pure-content plays, and capital-intensive hardware without a clear enterprise channel. The emphasis remains on B2B technology that can be distributed through Japanese corporate partnerships.

Yes. BigBang Angels regularly co-invests with Japan-based venture firms and Korean corporate venture arms. This syndication approach serves as its primary bridge into Tokyo, allowing portfolio companies to access follow-on capital and commercial relationships without the firm needing to maintain a full-time office in Japan.
