For the first time, your product's success isn't moving your revenue in the same direction. The more people use the thing you built, the worse the numbers look. Why?
Because you didn't change your pricing model. And at best, you've opened a gap between the value you deliver and the money you capture. At worst, every interaction with that feature now costs you more to serve than it earns — and your own success is draining your revenue.
That's the trap. Not that the feature failed — that it worked, on a pricing model that can't survive its own success.
But there's another way to read that same situation. The pricing model that's now exposed was never a law of nature. Someone chose it. And the moment a model stops fitting reality is the moment a market is open to be disrupted — not by adding more feature capability, but by changing the way you charge. And almost nobody is treating it that way yet.
The "obvious" model was once a bet
Remember when you paid for a movie one at a time — plus a fine if you returned it late? Netflix changed nothing about the product. Same DVDs, same envelopes. It just changed the unit it charged for — from "a rental" to "a month of unlimited access." Blockbuster kept the old unit. We know how that ended.
The model we now treat as obvious was a contested bet at the time. Someone had to choose the unit — and choosing it well was the whole game.
The same decision is being fought over right now — and nobody's won yet
That bet is back on the table. AI broke the assumption underneath SaaS pricing — that serving one more user, or one more action, costs basically nothing — and the entire industry is now experimenting in public to find the new unit. The tell that it's unsolved: the best companies in the world are arriving at completely different answers.
Intercom charges per outcome. Its AI tool, Fin, bills $0.99 per outcome — and an outcome only counts when Fin actually delivers one: either it resolves the customer's issue, or it successfully completes a workflow that hands off to a human. You don't pay for attempts that go nowhere. Their stated principle: pricing should track value delivered, and the vendor should carry the risk when the product doesn't perform. The unit isn't a seat or a message. It's a result.
Notion changed its model twice in roughly a year. It started selling AI as a separate per-seat add-on, then in 2025 killed the add-on and bundled AI into its core paid tiers, then layered a usage-based credit system on top for heavier workflows. Add-on, then bundled, then bundled-plus-consumption — three structures in quick succession, on the same product.
Zendesk had to legally define a word. It bills per "automated resolution" — but to do that, it had to define exactly what counts as resolved: a ticket the AI closes without human help, confirmed after 72 hours of no further activity. Read that again. They had to write a 72-hour rule to make the word "resolved" billable. That's how hard defining the unit actually is.
And the reversals tell you nobody's confident: Slack and Loom both launched AI as a per-user add-on, then later folded it into their core pricing — the same retreat Notion made. Four serious companies. Per-outcome, bundled, per-defined-resolution, add-ons-then-not. Multiple public reversals. No consensus winner.
Nobody has agreed yet — which is precisely why this is a live product problem and not a settled best practice you can copy.
So what can you do about it?
For most of SaaS history, pricing landed on a PM's desk as a given. Finance or the founders set the model; you built, sometimes tested, and shipped it. The model was the weather — something you worked under, not something you touched. That's over. When the unit of value is unsettled, choosing it is a product decision — and it belongs to the person closest to how customers actually get value. That's you.
First: find your unit of value. Not the price — the unit. The thing your customer would happily pay for because it maps to a win for them. You don't find it in a spreadsheet. You find it the way you find anything real about your product: interviews, watching where value actually lands, then testing whether they'll pay against that unit. Intercom landed on "an outcome," Zendesk on "an automated resolution" — units someone discovered by understanding the customer, not by picking a number.
Second: test the model itself. Not just the price point — the structure. Per seat, per outcome, bundled, metered, hybrid. Treat it like any other part of the product: ship a version, watch what happens, change it when it doesn't fit. Notion changed its structure twice in a year and is stronger for it.
Your next real release might not be a feature. It might be the way you charge for the ones you already shipped.
