From Fighter Jets to Water Wells - The Reinvention of Robert Reagan

He hunted submarines from the sky, helped build self-driving cars at General Motors, and scaled a fintech startup to a 125 million dollar valuation. Today, Robert Reagan pulls water well pumps out of the North Texas ground, and he is convinced the same handful of principles win in every one of those worlds.

In this episode, Reese sits down with Robert Reagan, CEO of Flowcore Water, a water well and plumbing company serving the Dallas-Fort Worth Metroplex, to talk about discipline, faith, and what actually builds a business that lasts. Robert opens up about running mission crews on submarine-hunting aircraft off the coast of Libya during the fall of Gaddafi, engineering test vehicles for GM's autonomous vehicle program in the wake of the DARPA challenge, and coming on as employee number three at a Y Combinator-backed mortgage startup that grew from three guys on laptops to a 125 million dollar valuation. He shares why he hires for coachability instead of a perfect resume, how he builds his own talent when the skill does not exist to hire, why he refuses to compete on price, how he uses AI to train technicians and analyze every customer call, and how faith and excellence sit at the same table in the trades.
