Kaisi Chang is a venture capital investor at Source Code Capital who specializes in new retail and OMO (online-merge-offline) investments, authoring the firm's flagship research reports that frame retail evolution through traffic management and data systems rather than traditional sales metrics. Unlike most investors who focus on either early-stage or growth-stage deals, Chang leads investments across both stages within the same retail verticals, combining his engineering and Cambridge doctorate background with cross-over private equity experience to support companies from platforms like Bytedance and Ke Holdings to consumer brands like usmile and Narwal.
