What if the most powerful tool a leader has isn’t a strategy, but a single question?

In this episode of Built Not Born, host Sage Nye sits down with Bob Brennan, four-time CEO, executive coach, and board director, to unpack how great leaders use inquiry instead of instruction. Bob scaled Iron Mountain from $1.8 billion to $3.2 billion in revenue and led Veracode through its $614 million acquisition by CA Technologies. He explains why his psychology background shaped every company he ran, and why “What can I do to be more effective?” is the one question he insists every leader ask.

Bob breaks down how to step into a company as CEO and cut through competing agendas, why withholding feedback is unkind rather than benevolent, and how getting defensiveness out of an organization changes everything. He shares the two red flags he never ignores in a hire, why most CEOs don’t give themselves time to think, and how to empower a team without micromanaging it.

The conversation also covers managing investors as owners, why a high headline valuation can be a trap, and why the best founders make everyone else the hero. This episode is a practical playbook for founders and executives who want to lead through questions, build future leaders, and scale without losing the people who make it work.
