Fractional CTOs in San Antonio Making Things Happen in 2025

San Antonio Interim Chief Technology Officers to Know

San Antonio is quickly becoming one of Texas’s most dynamic tech corridors. While it may not have the spotlight of Austin (yet), the San Antonio–New Braunfels metro is quietly building momentum—thanks to a thriving cybersecurity ecosystem, a growing number of SaaS startups, and a strong base of enterprise and defense tech talent.

But as companies scale, they’re confronting a familiar challenge: How do you bring in senior technical leadership without the full-time cost, risk, or wait?

The answer? Fractional CTOs.

Fractional Chief Technology Officers provide flexible, embedded leadership for startups and scale-ups that need clarity, speed, and technical expertise—but not a full-time executive hire. Whether guiding platform architecture, advising on product strategy, or mentoring engineering teams, these leaders are helping San Antonio’s innovators scale smart.

At Digital Reference, we’ve identified a standout group of San Antonio-area fractional CTOs already shaping the next wave of regional growth.
