W.T.T. Investment

W.T.T. Investment was established in Taipei in 1997 to steward the wealth created by Tsai Wan-Tsai, who built Fubon Group into one of Taiwan's largest financial conglomerates. The office operates under the direction of his sons, Daniel and Richard Tsai, who chair the group's listed insurance and financial arms. The family office pursues a multi-strategy mandate, moving across private equity, venture capital, real estate and fund-of-funds commitments. Its venture book spans seed through late-stage rounds, covering digital health, agri-food tech, biotech, climate technology and AI. Confirmed portfolio interests include alternative-protein companies and a luxury asset allocation that maps onto the family's broader art and culture holdings. Geographically, the office screens opportunities across North America, Europe and Asia, often co-investing directly or through special-purpose vehicles alongside institutional partners. While headcount is undisclosed, operational decisions run through managing director Hyunju Yang and partner and director John Wang. Alongside the financial portfolio, the Tsai family controls a mix of trophy real estate — including the Fubon Xinyi A25 mixed-use complex in Taipei — as well as the Fubon Guardians and Fubon Braves sports franchises. Philanthropic vehicles include the Fubon Art Foundation and Fubon Charity Foundation, which house a collection featuring works by Auguste Rodin. What distinguishes W.T.T. Investment from a generic family pool is its structural proximity to Fubon Financial itself: the two brothers sit atop a publicly traded insurance and banking giant while running a private investment office in parallel. That architecture gives the office a pipeline into Asian financial services deal flow and a permanent-capital base that most single-family offices cannot replicate.

Frequently asked questions

Who runs investment decisions at W.T.T. Investment?

Day-to-day investment execution is led by managing director Hyunju Yang and partner/director John Wang. Strategic oversight rests with principals Daniel and Richard Tsai, who respectively chair the broader Fubon Group and Fubon Financial. The late patriarch Tsai Wan-Tsai founded the underlying industrial fortune.

How is W.T.T. Investment related to Fubon Financial?

W.T.T. Investment is the private single-family office of the brothers who control Fubon Financial. Daniel Tsai and Richard Tsai sit atop the publicly traded insurer and bank while running the family's personal investment vehicle separately, giving the office a unique view into Asian financial services deal flow.

Does W.T.T. Investment make direct investments or only allocate to funds?

The office uses multiple structures: direct co-investments and SPVs, fund-of-funds commitments, and direct private equity and venture deals. Its venture book targets seed through Series C stages, and it evaluates fund commitments alongside its direct operations.

Which sectors does W.T.T. Investment explicitly prioritize?

Confirmed focus areas include digital health, agri-food technology, biotech, climate technology, luxury, healthcare services, enterprise software, AI/ML, and Web3 & blockchain. The luxury allocation aligns with the family's broader art-museum and cultural interests.

Where does the underlying wealth come from?

The fortune originates with Tsai Wan-Tsai, who founded Taiwan's Fubon Group — a conglomerate spanning banking, insurance and securities. His sons Daniel and Richard now chair the listed financial entities and steward the family's private capital through W.T.T. Investment.
