VenturesLab

VenturesLab was founded in 2005 by Mark Mai (Mai Gang), a Chinese entrepreneur who gained prominence as a vocal early supporter of Bitcoin. Originally structured around a technology incubator co-founded with Silicon Valley investor Tim Draper, the entity evolved into a personal investment vehicle as Mai's crypto holdings appreciated. Today the firm runs a mix of liquid and illiquid assets out of Shenzhen and Beijing, reflecting the profile of a founder-led family office that reinvests concentrated technology proceeds. Strategy spans three formats: direct early-stage private investments, secondary-market public-equity positions, and LP commitments into external venture funds. Sectors targeted include fintech, enterprise software, and digital media. Known portfolio anchors include a long-held equity or token position in the OKX exchange (formerly OKCoin), whose founder Xu Mingxing Mai mentored and backed at inception. The firm also routed LP capital through the DOS Capital special-purpose vehicle. On the public side, VenturesLab has traded positions in US- and Hong Kong-listed technology companies, though it does not disclose its current book. The firm runs a lean operation with a small core team. Mattan Lurie serves as portfolio manager, overseeing day-to-day investment activities. Beyond the securities portfolio, VenturesLab holds commercial real estate in Beijing under the Venture Space brand. The firm's influence in crypto extends through the relationships its founder cultivated: He Yi, a co-founder of Binance, has publicly credited Mark Mai with introducing her to the digital-asset industry. In early 2025, the firm maintained its dual-city presence while continuing to participate in venture rounds tied to the Asian crypto and fintech ecosystem. Structurally, VenturesLab is unusual because it is neither a pure crypto hedge fund nor a conventional family office — it is the personal investment apparatus of an individual whose network and reputation inside the Chinese digital-asset industry function as a sourcing and value-creation engine. This model, common among early Bitcoin holders who converted token wealth into operating businesses, means VenturesLab's mandate shifts with its founder's convictions rather than a committee-driven allocation framework.

Frequently asked questions

Who makes the final investment decisions at VenturesLab?

Founder Mark Mai (Mai Gang) controls the firm's investment direction. Portfolio-related execution is handled by portfolio manager Mattan Lurie, who runs day-to-day activities. The firm does not have an investment committee in the institutional sense; it operates with the discretion typical of a single-principal family office.

What is VenturesLab's relationship to the OKX exchange?

Mark Mai was an early mentor and backer of OKX founder Xu Mingxing (also known as Star Xu). VenturesLab holds an equity or token position in the exchange group, which originated as OKCoin. The relationship represents one of the firm's most significant venture outcomes.

How did the founder generate the capital that VenturesLab deploys?

Mark Mai accumulated wealth as an early-stage technology investor and through a large early position in Bitcoin. He was among the first prominent Chinese figures to publicly advocate for Bitcoin, and his subsequent investments in crypto infrastructure — particularly OKX and the mentorship of Binance co-founder He Yi — compounded those early gains.

Does VenturesLab take outside capital from institutional LPs?

No. VenturesLab is structured as a family office and investment holding company that manages Mark Mai's personal capital. It does not market funds to external institutional limited partners, although it has co-invested alongside outside entities and used SPVs like DOS Capital for select LP commitments.

Which sectors or industries does VenturesLab focus on?

The firm concentrates on fintech, enterprise software, digital media, and artificial intelligence. Its portfolio reflects a bias toward founder-led technology companies in China and the US, with a notable track record in digital-asset exchange infrastructure and blockchain-adjacent businesses.

In which geographies does VenturesLab actively invest?

Primarily China and the United States. The firm runs operations out of Shenzhen and Beijing and has historically deployed capital into early-stage consumer and crypto-focused companies in both countries.

Is VenturesLab a venture capital firm or a family office?

It is a hybrid. While its activities include direct venture investments and LP fund commitments, VenturesLab is fundamentally the personal family office of Mark Mai. It does not raise third-party funds, and its mandate aligns with the founder's own balance sheet, which also includes public equity and real estate.
