E287: What Separates Top Decile Managers from Everyone Else

47 minutes

What separates enduring investment firms from those that quietly break as they scale?

In this episode, I talk with Chris Brimsek, Managing Partner of CAB Advisory, about the unseen mechanics behind building durable alternative investment firms. Drawing from his experience as Chief of Staff to David Rubenstein and former COO of Carlyle’s $15B Infrastructure & Energy business, Chris explains why culture, judgment transfer, and succession—not deal mechanics—are the true bottlenecks to long-term performance. We unpack how elite leaders create environments without intellectual hierarchy, why forgiveness builds trust faster than perfection, and how emerging managers can avoid the most common traps as they scale.

Highlights:

Why the best firms eliminate intellectual hierarchy, not decision hierarchy

How great leaders use mistakes to build confidence and trust

“Expect what you inspect”: using questions to shape culture

Why most GPs underestimate the challenge of running a business, not a fund

The difference between managing deals and building a firm

Succession as knowledge and judgment transfer—not titles or economics

Lessons from fighter pilot debriefs applied to investment decision-making

Why non-economic factors dominate talent retention

How GP stakes are reshaping incentives and firm-building

The biggest silent risk facing emerging managers today
