Evolution has been a valuable partner to Slack, starting with guiding us to develop our core values and helping us live them every day. Geoff and Matt advised on the development of leadership programs and people processes that reflect our fundamental beliefs, and their team at Evolution has coached many of our leaders. I highly recommend working with Evolution in the early stages of scaling a company to establish an organization’s distinctive culture and provide leaders the confidence and tools they need to thrive.

Jasper Weir, President, Task Us

I consider executive coaching as important as making an executive hire, so I interviewed 4 coaches before deciding to work with Matt and Evolution, and it was a great decision.

Matt helped me dig deep to help me discover who I am as a leader and a person. He helped me establish a framework for decision making that’s far more valuable than the standard tactical coaching that only addresses surface level issues. Our work was nothing short of transformational on a business and personal level.

Evolution has been an essential partner to slack in helping us to distill what makes us unique, articulate those core values, and then build leadership and employee programs that reflect and reinforce that essence.

I have worked with Evolution continuously for well over a year, as have many of the senior people on my team, and I highly recommend Geoff, Matt and the team at Evolution. In addition to being a pleasure to work with, Geoff has been very effective as an executive coach, and he and the others at Evolution have greatly supported us with leadership development. Evolution has had a significant impact on our organization and many of its senior leaders.

I found a tremendous amount of value working with Matt and Evolution. Specifically, he gave me the the opportunity to reflect in a structured way and helped me create practical strategies to deploy when I was most at risk of acting out of my leadership values. Over time, he helped me habitualize those behaviors and I was able to gain a high level of trust and responsiveness from the team I worked with.
