What is EOS?

EOS, the Entrepreneurial Operating System®, is a complete set of simple concepts and practical tools that have helped thousands of entrepreneurs around the world get what they want from their businesses.

A people operating system that harnesses human energy through a simple set of tools and principles. You’re able to solve issues before they become problems, get the right people in the right seats, make meetings so productive that you actually look forward to them, and build a culture of accountability. When you run on EOS, everyone is working toward the same goals. Your business runs more smoothly and profitably. You break through the ceiling to achieve growth. And you simply enjoy life more.

Implementing EOS will help your organization with the following:

  • Get everyone in your organization 100% on the same page with where you’re going and how you plan to get there.
  • Instil focus, discipline, and accountability throughout the company so that everyone executes on that vision – every day.
  • Help your leaders become a more cohesive, functional, healthy leadership team.

Nancy helped us implement the EOS system so that we could run our business instead of the business running us. We have less frustration and greater control, even in tough times. Our A+ talent is 100% aligned on where we’re going and how we’re going to get there. Nancy puts great emphasis on the genius in the room. She asks insightful questions and keeps us focused on what really matters.

- Michele Bailey, President & CEO, Blazing Agency

We had the pleasure to work with Nancy to facilitate our annual strategic planning meetings. Nancy’s EQ and ability to “read the room” during the implementation of EOS with our team was incredible. Not only does she live and lead by the EOS core values, but also has amazing skills of challenging the team with a gentle assertiveness that commands attention and trust. Without having ever met our team, her approach was tailored perfectly to fit the personalities of our leadership members allowing us to gain strength and alignment in a very authentic and quick way.
