Prioritizing the Product: Newsletter as Core

In this episode, I talk with CJ Gustafson, the former CFO behind Mostly Metrics. CJ didn’t come from journalism or media. He came from operating. He started writing to document the playbooks he’d built as a finance executive. That side project turned into a $3 million business with no full-time employees, built around a narrow, high-value audience of CFOs.

We talk about why subscriptions are a useful base but not where the money is in B2B, how sponsorships actually work when sales cycles are long and considered, and why CJ has deliberately avoided becoming an events company. Mostly Metrics is now largely sponsorship-driven, sold out well into the future, and optimized for cash flow and leverage.
