Who We Are
PeerSix was conceived to help companies create sustainable, long-term value. While leaders would love a silver bullet, there’s no one-size-fits-all strategy. Companies scale and mature; competitors enter the market; consumer preferences evolve; macro-economic conditions shift. The only constant is change. Responding effectively is easier said than done. After $500M+ in consulting services sold and delivered - across 100 SaaS businesses and 50 of the Fortune 500 - we’ve seen the same challenges get in the way of value time and again.
PeerSix is here to help. We’re proven operators with more than 30 years experience helping companies define the right strategy and execute with speed, scale, and agility. We’ve worked across corporate strategy, capital deployment, product strategy, growth and go-to-market, marketing, sales, and value tracking. We’ve also seen how those the challenges impact different roles, having worked as frontline sellers, built and scaled organizations as managers, and driven revenue acceleration as consultants.
So go ahead, delight your customers and investors at the same time, with PeerSix.
"If I had only one hour to save the world, I would spend fifty-five minutes defining the problem, and only five minutes finding the solution."

Meet the Team
Evan Markley
Founding Partner
Washington, D.C., USA
Evan is deeply committed to helping people and organizations become the best versions of themselves. He is most energized when he’s working with people on what’s most important to them. Some say he was the best business case modeler this side of the Rio Grande. Outside of work, you can find Evan on a golf course, experimenting with cocktails, or finding new restaurants to try. He also enjoys classic cinematography, dry humor, and great design.
Dr. Jeff Collins
Founding Partner
Chicago, IL, USA
Jeff is a passionate advocate for leveraging the quantification of expected value to make informed investment decisions. In this pursuit he has spent the last 16 years working with hundreds of companies across industry and market segments to ensure that “the juice is worth the squeeze.” A recovering academic, Jeff’s approach remains academic, rooted in building a sound understanding of the potential benefits and costs of a technology investment through discovery and analysis. Finally, Jeff understands that the best technology does not create value unless it is effectively implemented and utilized. This truism has meant change management is his side hustle. When not working with great companies to transform their organizations you can find Jeff with his family or enjoying the sun walking or biking in his adopted hometown, Chicago.
