Run the Numbers

In this special, table-turning episode of Run the Numbers, CJ Gustafson steps out of the host’s chair as Paul Stansik—Operating Partner at ParkerGale and author of the Hello Operator newsletter—takes over the interview. What began as a planned discussion on annual planning best practices quickly evolves into a candid deep dive on Mostly Media, CJ’s growing niche B2B media business, and the thinking behind his own operating plan for the year ahead. Fresh off exiting his CFO role in January 2025, CJ walks through the origin story of Mostly Metrics, how it scaled into a broader media platform, and what it’s like being “the boss of me” for the first time. Paul presses on the real questions—growth opportunities, monetization, and strategic tradeoffs—making this episode a transparent look at how a modern, metrics-driven media business is built and run.—SPONSORS:RightRev automates the revenue recognition process from end to end, gives you real-time insights, and ensures ASC 606 / IFRS 15 compliance—all while closing books faster.

They discuss why what ChatGPT says about your product may become a core marketing KPI, the resurgence of direct mail and physical touchpoints in an AI-saturated world, and why “almost as good as a human” is a dangerous positioning for AI-driven products. The conversation also explores AI monetization paths through advertising, the risk of an AI infrastructure timing mismatch leading to a broader financial pullback, and what historical parallels like railroads and the Sears catalog can teach us about today’s buildout. The episode closes with real-world pricing lessons, from energy-as-a-service solar subscriptions to the surprisingly massive standalone economics of Apple’s AirPods, tying together how distribution, perception, and monetization shape durable growth.—SPONSORS:Pulley is the cap table management platform built for CFOs and finance leaders who need reliable, audit-ready data and intuitive workflows, without the hidden fees or unreliable support.

In this episode of Run the Numbers, CJ Gustafson sits down with Larry Contrella, General Partner at JMI Equity, to unpack how JMI invests in software without financial engineering or roll-up strategies. Larry explains how the firm builds conviction through founder relationships, long-term partnership, and a product-and-brand-first view of durable growth. They discuss how JMI supports companies through scaling, why operating partners keep returning, and how underwriting looks different in mission-driven sectors like K–12 and nonprofit tech where customers are schools and communities, not Fortune 500s. Larry’s background as a competitive runner at Penn ties the conversation together with a clear ethos: patience, discipline, and playing the long game.—SPONSORS:Mercury is business banking built for builders, giving founders and finance pros a financial stack that actually works together.

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.—SPONSORS:Sage Intacct is a cloud financial management platform that replaces spreadsheets, automates workflows, and keeps your books audit-ready as you scale.

They unpack why point-solution companies like Untuckit and Raising Cane’s can outperform diversified rivals, examine how competition actually strengthens category demand, and break down the gray zone of mid-market venture exits where founder incentives and investor expectations diverge. The conversation ranges from private equity roll-ups to the realities of cold-calling returning as a top-performing growth channel, to pricing transparency, algorithmic price discrimination, and how everyday behaviors—from mall Santas to $12 club water—reflect deeper strategic forces. It’s a fast, practical look at how operators can stay focused, understand market pressure, and avoid chasing the wrong game.—SPONSORS:Pulley is the cap table management platform built for CFOs and finance leaders who need reliable, audit-ready data and intuitive workflows, without the hidden fees or unreliable support.
