Let's say we're a golf company and you say there's 50 million golfers in the US, that's our TAM. You'll find pretty quickly that there aren't 50 million golfers who play golf on a frequent basis, maybe 20 million. You're omitting a key factor which is commitment.
Commitment is the variable founders forget — 50M golfers ≠ 50M subscribers
For subscription products the gating variable isn't whether someone fits the category — it's how committed they are. Surfline doesn't care how many people have surfed once; it cares how many surf often enough to pay. Cut your TAM by commitment frequency before you model anything.

Free location daily + paid safety: the freemium formula
Life360's freemium formula pairs free location sharing — which drives 22 app opens per day from parents — with paid safety features like crash detection and roadside assistance. Safety is something users pay for but forget about without prompting; daily location utility keeps the product top-of-mind so the safety upsell lands when a real need arises. Without the daily engagement layer, safety alone would be a dormant, low-conversion subscription.
There's a play for whatever you're stuck on.
