S-Cubed Capital

S-Cubed Capital was formed in 2012 by Mark Stevens after his time as a Sequoia Capital managing partner. Stevens built the capital base through early-stage technology investments, most notably Nvidia. The office also incorporates philanthropic vehicles run with his spouse Mary Stevens. The firm commits across venture stages from seed through growth, real estate, hedge funds and direct co-investments. Positions include prior holdings in Innovium, acquired by Marvell Technology in 2021, alongside current exposure to semiconductors, enterprise software and consumer technology. Geographic reach covers North America, Europe and South America. Real-asset activity centers on residential and ranch properties in Steamboat Springs, Colorado and Atherton, California. Deployment totals approximately $5B. The team includes family members Sky Stevens and Mary Stevens in philanthropic work. Mark Stevens has served on the USC Board of Trustees since 2001 and joined the Giving Pledge in 2013. No operational announcements have surfaced in the past 24 months. The office operates without external limited partners, allowing direct control over allocation pacing and co-investment terms. This structure separates it from multi-family platforms and from Sequoia Capital itself, where Stevens retains special limited partner status.
