About
S3 Ventures is a U.S.-based venture capital firm founded in 2005 and headquartered in Texas, investing in technology companies across the United States. The firm focuses on early to mid-stage investments, primarily in business software and healthcare technology.
S3 Ventures typically leads Seed, Series A, and Series B rounds, with initial investments ranging from approximately $500K to $15M and the ability to deploy up to $25M per company over its lifecycle.
