Tim Keymer

Fractional Operating Partner

Tim specializes in bringing order to the beautiful chaos of high-growth startups. Decisive and action-oriented, he doesn’t just advise; he takes ownership of the work that matters most—transforming executive vision into measurable execution.


With over 20 years in the venture-backed world, Tim has a proven track record of scaling product and engineering teams, tripling company valuations, and navigating multiple organizations through high-value acquisitions. Tim serves as a force multiplier for Founders and CEOs by unblocking their people and aligning their priorities so leaders can get back to leading. He helps Founders transition from frantic, "everyone-does-everything" growth to streamlined, exit-ready operations. 


Beyond the exits, Tim is a builder by nature. He lives in Minneapolis, MN with his wife and their three children, where he is often found tackling a DIY home project or coaching his kids' sports teams. Drawing on his values as an Eagle Scout, he operates by the same core principles in all areas of life: Do the right thing, support the team, and never stop improving.
