Subscriber growth, churn realities, and list scale

In this year-end episode of Mostly Growth, CJ Gustafson, Kyle Poyar, and Ben Hillman reflect on what it actually takes to build a modern media business around newsletters and podcasts. They unpack CJ’s first year going full-time, comparing creative intuition versus metric-driven operating styles, and discuss what content truly drives growth. The conversation also covers distribution dynamics, the emotional reality of unsubscribes and burnout, and closes with a candid look at monetization, team building, and the tradeoffs between simplicity and scale.
