S3 Ventures

Founded in 2005, S3 Ventures is the largest and longest-serving venture capital firm born in Texas and investing nationwide. We empower visionary founders with the patient capital and true resources required to grow extraordinary, high-impact companies in Business Software and Healthcare Technology. With over $1B in assets under management, we lead Seed, Series A, and Series B rounds—with initial investments ranging from $500K to $15M and the capacity to invest $25M over the life of a company. Our 75+ investments have raised over $3.5B in financing and resulted in 35+ exits—collectively valued at over $3B. Since our inception, we have been backed by a single philanthropic family with a multi-billion-dollar foundation. With this sole-LP structure, we are undistracted by fundraising and unencumbered by many of the constraints faced by traditional VC firms—better aligning us with the needs of founders.
