92: The CTO Playbook: How to Build Trust, Consistency, and Psychological Safety in Engineering Teams

The difference between a good CTO and a trusted one often comes down to a personal playbook.

Build your own CTO Playbook at www.theCTOplaybook.com — the leadership platform built for the full CTO journey. Coaching, podcast, and community to help you lead with clarity, confidence, and strategic impact.

Sam Boswell is the CTO of Terralayr, an energy tech company focused on solving global energy storage challenges. With a background in high-risk infrastructure and scaling engineering teams, he brings a practical lens to how leadership actually works.

At the center of that philosophy is a simple idea. Engineers don’t follow leaders because they’re the most technically brilliant person in the room. They follow leaders who are consistent.

That consistency doesn’t happen by accident. It comes from a personal playbook. A set of lived principles that shape how decisions are made, how problems are approached, and how people are treated.

We get into how that playbook forms over time, why documenting how you think matters more than most leaders realize, and what happens inside teams when that consistency is missing.

The result is a grounded look at leadership that moves beyond theory. It shows what it takes to build trust, create safety, and lead in a way people actually want to follow.
