Product led growth

The trade being made

Sales led growth spends money on people to move a buyer from interest to purchase. Product led growth spends it on the product doing that itself: a free tier or a trial, self-serve signup, pricing published on a page rather than quoted on a call.

The appeal is obvious and mostly correct. The cost of serving one more prospect goes to nearly nothing, the buyer gets to try before deciding, and the feedback loop shortens from a quarter to an afternoon.

The part that gets skipped is that the burden moved rather than disappeared. Everything a salesperson used to do (qualify, explain, configure, reassure, follow up) now has to be done by the product, the pricing page and the onboarding, in that order, to somebody who is not paying attention and has four other tabs open.

Time to first value is the whole metric

If there is one number in this model, it is how long it takes a new user to get something real out of the product, unaided.

Not a completed tour. Not a checklist with five ticks. Something they would have been sad to lose: a report that told them something, a file converted, an answer they did not have. Everything else in the funnel is downstream of that moment, and if it sits behind an integration, an import or a config screen, then the honest reading is that the product is not self-serve yet and a free tier will mostly generate abandoned accounts.

The associated discipline is unglamorous: cut steps before the win, move steps after it, and let people see something useful before you ask them to sign up for anything. A signup form placed before any value is a tax collected from everybody, paid by the people least sure they want the thing.

Where it goes wrong

Bolted onto a product that needs a human. Complex, configurable, multi-stakeholder products are not disqualified from self-serve, but they need a genuinely small slice of themselves that works alone. Opening the full product to a stranger and calling it a trial produces a support load, not a pipeline.

A free tier with no reason to leave it. The free version has to be useful enough to be adopted and bounded in a way that the successful user grows out of. Bounded on the wrong axis and your happiest users never pay, while your frustrated ones churn.

Pricing that hides. Self-serve buyers will not book a call to learn the price, they will leave. If the price is not on the page, the model is not really product led, whatever the deck says. What the page should show is a ladder rather than a number, and the shape of that ladder is a strategy the buyer can read in five seconds.

No expansion path. Without a limit that grows with usage, the model has capped itself at the entry price, and the whole economic argument for it goes away.

It is a flywheel or it is just a cheaper funnel

The reason this model gets talked about as growth rather than as a discount is that it is supposed to loop. Users invite colleagues, teams outgrow limits, public artefacts pull in strangers, and each turn leaves something behind that makes the next one cheaper.

That claim deserves the four questions any loop has to pass. Name the thing turn one leaves behind. Know the turn time. Check that friction falls. Check that the next turn does not need proportional spend. A free tier where nobody invites anybody and nothing accumulates is a price cut with extra steps.

You can tell which model a competitor is running, from outside

This is one of the easier reads in competitor watching, because the evidence is structural rather than statistical.

Is the price on the page or behind a call. Does signup ask for a card. Is there a free tier, and what axis is it bounded on: seats, volume, features, time. Is there public documentation and an API, which is a product built to be adopted without help. Does the pricing page carry a tier that appeared without an announcement. And the slowest signal to fake: who they are hiring. Ten account executives is a sales led company regardless of what the homepage says; growth engineers and onboarding designers are the other answer.

Those signals also move. A company adding a sales-assist tier, or quietly removing the free plan, is telling you what their unit economics did last quarter, months before anybody writes about it.
