Mark Stevens is the Managing Partner and founder of S-Cubed Capital, a private family office in Atherton, California, after serving as a managing partner at Sequoia Capital from 1993 to 2011. His firm operates an endowment-style investment strategy that backs venture capital managers and invests directly in early-stage companies across agribusiness, technology, real estate, and energy. Stevens typically leads seed-stage investments in the United States, though specific check sizes are not publicly disclosed. Notable portfolio companies include NVIDIA, where he invested in 1993 and served on the board for over a decade, as well as Second Spectrum and Innovium. His fortune is primarily derived from his significant stake in NVIDIA, which he owns directly and via trusts. A distinctive point of his approach is the endowment-style model that blends direct venture investments with broader asset classes like real estate and energy. Stevens also holds a minority ownership stake in the Golden State Warriors, serving as an executive board member.
