After product-market fit, the cheapest growth is the users you already have. Most teams keep buying new ones while the funnel quietly leaks the ones they already won.
Post-PMF, the most expensive habit is chasing new users while the funnel leaks. Acquisition feels like progress, so teams keep spending at the top - while the users they already paid to win drop off at a step nobody is watching.
Every one of those drop-offs is revenue you were already close to earning. The visitor who reached your store page and did not install. The signup who never activated. The trial that went cold. Fixing those leaks is almost always cheaper - and faster - than buying more traffic to pour into the same holes.
When retention or activation is weak, more acquisition just increases the volume flowing through a leaky funnel. The absolute numbers might tick up while the budget flows, but the economics get worse, not better, because you are paying full price to replace users you should never have lost.
The tell is a gap between how many users you win and how many stick. If the top of the funnel looks healthy and the bottom does not, the problem is not acquisition. It is everything between first open and the moment that matters.
Map the full journey and name every drop-off, screen by screen - from first open, through onboarding and activation, to the point of real value. Not vague UX opinions, but specific, prioritized fixes: quick wins first, structural changes flagged clearly. You will almost always find that closing two or three specific leaks moves revenue more than a quarter of new features or a bigger ad budget.
Keep the users you already have, and every acquisition dollar you spend later works harder.
