Our Founder Story

Built by a family of founders. Designed for a generation of builders.

Cole MacMillan MBA, Second Generation Founder

As a second-generation founder, I grew up watching entrepreneurship in action through Halcyon Consulting Group Inc. I saw how the right guidance, frameworks, and operating systems could help leaders turn ideas into impact.

But I also saw the limitation: traditional consulting could only help a small number of founders.

Execution Institute was created to change that.

We’re building a digital operating system for pre-growth companies — giving founders access to AI-powered assessments, execution playbooks, leadership frameworks, and practical tools once reserved for larger organizations.

Our mission is to empower more founders to build companies that execute with clarity, grow with purpose, and become responsible stewards of their people, communities, and the planet.

We believe the next generation of great companies will not only create value — they will create lasting impact.
