Matthew Holthaus, Founder & Leadership Advisor
01

From the field to EVP

Matthew’s commercial leadership background includes HEINEKEN USA and his later role as Executive Vice President of Sales & Marketing at Clare Rose. His experience spans supplier and distributor responsibilities in the beverage alcohol industry.

His operating experience includes leading a $250M+ business, building and scaling a team from zero to 100, and guiding a team through an acquisition and a six-month labor stoppage. He also negotiated a ten-year agreement with one of the world’s largest brewers.

02

Operating experience before Proving Ground

At Clare Rose, Matthew’s route-to-market work included converting all 75 routes from driver-sell to presell and building a 100-person commercial organization. Portfolio and package-mix improvements delivered $2.1M in incremental annual gross profit.

These examples describe Matthew’s earlier executive operating experience. They provide context for his perspective on leadership and commercial execution; they are not results attributed to Proving Ground Advisory clients.

Why Proving Ground Advisory

“Somewhere on that climb the goal changed — from how far I could go to how far I could take the people with me.”

That is the idea behind Earn Your Next Level: helping capable people move toward the responsibility they are ready to take on, with clarity, accountability, and a practical plan for execution.

04

Two ways to work together

The Next Level Engagement is 90 days of private 1:1 advisory for leaders navigating a bigger role, greater responsibility, or a demanding transition. It includes an opening strategy session, weekly advisory sessions, and a practical action plan.

Commercial Performance Advisory is a separate conversation for beverage and distribution organizations seeking stronger leadership, portfolio focus, and in-market execution. The organizational engagement has its own scope.
