In their words
My brother Willy and I began building construction companies as teenagers in the 1990s. We didn't learn the industry from a textbook; we learned it on the jobsite, navigating the complexities of design-build projects for nearly three decades. That firsthand experience gave us a front-row seat to the 'reactive chaos' that defines the status quo. … As CEO of EquipmentShare, my mission is to replace that chaos with certainty through vertical technology integration.
