The question every AI founder asks is which model to use: seats, usage, or outcomes. Ramanujam's answer is that the model is not a preference, it is a readout of two properties your product either has or does not.
Attribution is whether you can prove the value you created, ideally against a KPI the business already tracks. Autonomy is whether the work happens without a human in the loop. Plot those and the archetype falls out, along with how much of the value you can defensibly claim.
Low attribution · Low autonomy
Seat-based or subscription
You cannot attribute much and there is a human in the loop. Charge per seat, then work on attribution to move right.
High attribution · Low autonomy
Hybrid
Copilot products like Cursor. Keep a seat fee for the assist, layer credits or tokens on top so heavier use pays more.
Low attribution · High autonomy
Usage-based
Backend and infrastructure that runs unattended but does not move a tracked KPI. Seats make no sense with no human; usage proxies the value.
High attribution · High autonomy
Outcome-based, the golden quadrant
Intercom's Fin charges per AI resolution and nothing when a human steps in. ChargeFlow takes a cut of chargebacks it recovers.
Ramanujam's numbers on where the market actually sits: hybrid is the most common model today, roughly 5 percent of companies run true outcome-based pricing, and he expects that to reach about 25 percent within three years. The companies already there capture 25 to 50 percent of the value they create, against the 10 to 20 percent that was considered good in classic SaaS.
