## About

Maximilian Ma Yung-kit founded the family office to manage the wealth generated by Lee Heng Diamond Company Limited, the Hong Kong diamond and jewelry group he chairs. His brother Lawrence Ma Yung-yee serves as CEO of the group and participates in office decisions. The structure preserves control within the immediate family while separating operating-company governance from investment activity. The office targets early-stage and seed opportunities in Asia, primarily through direct co-investments and SPVs. Confirmed vehicles include CoCoon, the entrepreneurship hub founded by Theodore Ma and Erica Ma, and the Lee Heng Charity Foundation. Geographic reach centers on Hong Kong with ancillary exposure across the region. Asset classes include venture positions, commercial real estate such as Sino Plaza, and a fine-wine collection. No public headcount or AUM figure exists. Adjacent vehicles comprise the CoCoon Foundation and the Lee Heng Charity Foundation. Lawrence Ma holds governance roles at the Diamond Federation of Hong Kong and the Gemological Institute of America. The office maintains an integrated ownership model in which family principals retain direct operating-company oversight alongside the investment mandate, a structure uncommon among pure-play single-family offices.
