Behind the Build: The Denim Group Story

In 2001, three founders started a cybersecurity consulting firm in San Antonio. Twenty-one years later, they sold it to Coalfire. In between: two decades of building one of the city's most respected tech companies, hiring and mentoring a generation of San Antonio talent, and figuring out the answers to questions most founders never get the chance to ask. This is the story behind that deal. The founding partners of Denim Group — Sheridan Chambers, Dan Cornell, and John Dickson — sit down together to talk about the origin, the build, the acquisition, and what they're doing now. The hardest years. The decisions that mattered. What they'd tell a founder starting today. And why they've stayed active in San Antonio's ecosystem, reinvesting time and capital into the next generation of builders. A rare, honest conversation from three founders who built it here, sold it here, and are still here.
