Before I owned a P&L, I thought I understood customers. Journey maps. Conversion funnels. NPS scores. I thought that was the job.

Then I became a CEO.

The question changed entirely. Not ‘how do we get them to convert’ — but what does it cost to acquire them, what do they spend over a lifetime, and what does it cost to serve them when something goes wrong?

The customer I thought I understood was a conversion event. The customer I actually needed to understand was a unit economic.

We stopped optimizing for traffic volume and started optimizing for customer quality. Killed campaigns that drove acquisition of the wrong buyer. Revenue per order went up. Returns went down. Cost to serve dropped.

Marketers think in journeys. CEOs think in economics. The best operators I’ve worked with hold both lenses at the same time.

Which one are you looking through right now?
