DOS Capital

Founder Mark Mai leads the firm's investment strategy, with Portfolio Manager Mattan Lurie handling day-to-day portfolio operations. The investment committee structure has not been publicly detailed, but decisions sit with the internal Mai family office team rather than external advisory boards. Tim Draper's role is as co-founder of the parent platform VenturesLab, not as a direct investment committee member at DOS Capital.

DOS Capital operates as a corporate investor — a structure that blends the principal-investing posture of a single-family office with the deal-execution discipline of a venture capital firm. It deploys the Mai family's own capital alongside select strategic co-investors, without the fundraising or LP-reporting obligations of a conventional fund manager. The corporate-investor designation reflects its dual mandate across private venture equity and liquid cryptocurrency fund positions.

The firm's primary origination channel runs through VenturesLab, the platform Mark Mai co-founded with Tim Draper. That connection provides deal flow from the Draper Venture Network, which spans hundreds of portfolio companies and co-investors across North America and Asia. DOS Capital supplements this pipeline with direct ecosystem relationships in Hong Kong, including active participation in HKVCA summits and the broader Greater China venture community.

The firm maintains exposure to both categories. It makes direct venture investments across seed, start-up, and growth stages, and its portfolio also includes cryptocurrency fund LP positions. This dual approach allows the firm to capture early-stage equity upside directly while gaining diversified exposure to digital-asset managers through fund commitments.

Venture-stage technology investments form the core of the strategy, with a particular emphasis on enterprise software and fintech. The cryptocurrency fund LP positions signal a deliberate allocation to digital assets. The firm has not published formal sector exclusions, though its deal flow — filtered through the VenturesLab and Draper network — tends to concentrate on technology rather than traditional industrial or real-asset verticals.

VenturesLab serves as the parent investment platform, co-founded by Mark Mai and Tim Draper. DOS Capital operates as the Mai family's dedicated investment entity within that platform. Draper is a co-founder of VenturesLab but is not listed as a principal of DOS Capital itself. The relationship effectively provides DOS Capital with infrastructure support and privileged access to the Draper Venture Network's deal flow and co-investor community.

The capital is drawn from the Mai family's wealth, anchored by Mark Mai's entrepreneurial and investment returns through VenturesLab and predecessor activities. The specific industry or company that generated the family's founding wealth has not been publicly disclosed. The family office structure suggests the capital base is permanent and not subject to external redemption pressures.
