“Rock & Sand is a powerful and practical mini-book for entrepreneurs. If you want to unleash growth in your organization, this book shares a simple, practical process and set of tools to get it done. Michael Synk brings his coaching and teaching skills — along with a community of highly capable and experienced coaches from Gravitas Impact — to provide a growth roadmap that can apply not only to businesses, but also non-profit organizations. The Rock & Sand framework matches up nicely as a complement to The Great Game of Business^® framework and toolsets, as evidenced by the inclusion of our Critical Number principles, in our Open Book Management philosophy, that is the foundation of The Great Game of Business.”

– Jack Stack Author of The Great Game of Business and Founder & CEO, SRC Holdings

“The insights of Rock & Sand brought more clarity to our executive planning team in a short period of time than anything we had experienced in the past. There is universal love among the founders of our business for this concept and the simplicity it creates.”

– Austin Baker CFO, National Enrollment Partners
