Episode notes

In this episode of Run the Numbers, CJ Gustafson sits down with Brian Brown, Chief Financial Officer and Treasurer at Rocket Companies, to unpack how Rocket has built a differentiated, full-stack fintech business far beyond its mortgage roots. The conversation explores Rocket’s approach to long-tail monetization, the strategic importance of mortgage servicing, and how recapture rates become a durable competitive advantage in volatile rate environments. Brian shares lessons from leading complex M&A transactions, managing a business that reacts in real time to macro signals, and building a finance organization that prioritizes storytelling, strategy, and cross-functional thinking over pure accounting prowess. The result is a wide-ranging discussion on what traditional financial services companies can teach modern SaaS and fintech leaders about metrics, brand, and disciplined execution.
