The Seat-Based Model Is Breaking
For two decades, SaaS pricing was simple: count the seats, multiply by a monthly rate, collect the check. The model worked because software value was roughly proportional to the number of people using it. But AI has broken that assumption. When a single user can do the work of five — or when an AI agent does work with no human in the loop at all — the seat count becomes a meaningless proxy for value delivered.
The data confirms the shift. Among the 50 fastest-growing SaaS companies in 2025, 68% now offer usage-based pricing as their primary or secondary model, up from 34% in 2022. The trend is accelerating.
Why Usage-Based Models Win
The economic logic is straightforward: usage-based pricing aligns vendor revenue with customer value. When a customer gets more value from the product, they use it more and pay more. When they get less value, they use it less and pay less. This alignment reduces churn, increases expansion revenue, and — critically — makes the sales conversation easier because the customer doesn't have to predict their usage upfront.
For AI-native products, the alignment is even tighter. The cost of delivering AI inference scales with usage, so usage-based pricing also aligns vendor costs with revenue. A seat-based AI product is essentially a bet that every seat will use the product heavily — a bet that almost never pays off.
The Buyer's Perspective
For software buyers, usage-based pricing is a double-edged sword. The upside: you only pay for what you use, trials are lower-stakes, and the vendor has a direct incentive to make the product more valuable. The downside: budgeting becomes harder, costs can spike unexpectedly, and the "unlimited" simplicity of seat-based pricing disappears.
The best usage-based products address the budgeting problem with spending caps, predictable tiers, and clear cost dashboards. The worst leave buyers with surprise invoices and no visibility into what drove the cost. When evaluating a usage-based product, the quality of the cost management tooling is as important as the product itself.
What Buyers Should Do
Three practical recommendations for navigating the usage-based shift. First, always ask for a cost estimate based on your actual usage patterns — not the vendor's "typical customer" benchmark. Second, insist on spending caps or alerts before signing any usage-based contract. Third, build usage monitoring into your procurement process from day one; the products that let you track consumption in real time are worth paying a premium for.
The shift to usage-based pricing is ultimately good for buyers who use software intensively and bad for buyers who purchase broadly but use narrowly. If you're in the latter camp, this trend is a forcing function to audit your stack and eliminate the products you're not actually using.
