The Right CTO, On Demand

30+ years of engineering leadership, AI-native architecture, and startup scaling experience, without the full-time overhead. I work with a small number of founders at a time.

Outcomes, Not Overhead


Technical Decisions That Don't Come Back to Haunt You

Architecture choices made early compound — for better or worse. I help you build on foundations that scale, so you're not rewriting everything at Series A.

Investor-Ready Technical Credibility

When your investors ask hard questions about your stack, your security posture, or your technical roadmap, you want someone in your corner who's been on both sides of that table.

A Force Multiplier for Your Dev Team

Whether you have two developers or twelve, senior technical leadership shapes what they build and how fast. I provide the strategic layer your team needs to execute with clarity.

Why Trey Overton


"I don't just advise — I architect, decide, and take ownership of outcomes alongside your team."
