1199: The CFO’s Biggest Challenge Isn’t AI—It’s Leading Through It | John Kinzer (Interim CFO), OneStream

John Kinzer still remembers sitting in a closed meeting at MCI, presenting revenue results, when something unexpected caught his attention. It wasn’t the numbers he was reporting—it was the questions coming from the FP&A team. Listening to their discussion, he realized, “I also want to see that side of it,” Kinzer tells us. That moment led him from revenue reporting into business planning, where a manager helped shape the analytical skills that would define his career.Looking back, Kinzer tells us those early experiences proved invaluable. Long-distance telephone plans behaved much like today’s subscription businesses, exposing him to churn analysis, lifetime value, customer acquisition costs, and cohort analysis long before SaaS became commonplace.Equally important was another lesson from a mentor: always look 18 to 24 months ahead. If you’re no longer learning, growing, or able to see your next opportunity, it’s time to start thinking about what’s next, Kinzer tells us. That advice influenced several career decisions, including his move into the dot-com world, where he participated in his first IPO by helping write an S-1 and develop the company’s long-term financial model.The same long-term mindset later shaped an even more difficult decision. After being passed over for his first CFO opportunity, Kinzer tells us he resisted the urge to react emotionally. Instead, he focused on developing new skills, particularly investor relations, believing the experience would prepare him for the future whether the opportunity came internally or elsewhere.For Kinzer, career progression has never been about chasing titles. It’s been about continually putting himself in positions where learning comes first—and trusting that leadership opportunities eventually follow.
