Warp's initial subscription model, offering a fixed number of AI credits, became unprofitable as heavy usage grew. They were forced to switch to a consumption-based model, trading user complaints for sustainable, margin-positive growth, a crucial lesson for pricing AI applications.

AI products with a Product-Led Growth motion face a fundamental flaw in their unit economics. Customers expect predictable SaaS-like pricing (e.g., $20/month), but the company's costs are usage-based. This creates an inverse relationship where higher user engagement leads directly to lower or negative margins.
Many AI coding agents are unprofitable because their business model is broken. They charge a fixed subscription fee but pay variable, per-token costs for model inference. This means their most engaged power users, who should be their best customers, are actually their biggest cost centers, leading to negative gross margins.
Standard SaaS pricing fails for agentic products because high usage becomes a cost center. Avoid the trap of profiting from non-use. Instead, implement a hybrid model with a fixed base and usage-based overages, or, ideally, tie pricing directly to measurable outcomes generated by the AI.
The dominant per-user-per-month SaaS business model is becoming obsolete for AI-native companies. The new standard is consumption or outcome-based pricing. Customers will pay for the specific task an AI completes or the value it generates, not for a seat license, fundamentally changing how software is sold.
The move away from seat-based licenses to consumption models for AI tools creates a new operational burden. Companies must now build governance models and teams to track usage at an individual employee level—like 'Bob in accounting'—to control unpredictable costs.
Anthropic is preventing users from leveraging its cheap consumer subscription for heavy, API-like usage. This move highlights the unsustainable economics of flat-rate pricing for a variable, high-cost resource like AI compute. The market is maturing from a growth-focused to a unit-economics-focused phase.
Switching a usage-based AI product to an unlimited SaaS model eliminates budget as a barrier, driving deep adoption. The new bottleneck becomes the client's time to process the AI's output, creating an opportunity to build features that automate this "last mile" of work.
In the age of AI, software is shifting from a tool that assists humans to an agent that completes tasks. The pricing model should reflect this. Instead of a subscription for access (a license), charge for the value created when the AI successfully achieves a business outcome.
The shift to usage-based pricing for AI tools isn't just a revenue growth strategy. Enterprise vendors are adopting it to offset their own escalating cloud infrastructure costs, which scale directly with customer usage, thereby protecting their profit margins from their own suppliers.
AI startups often use traditional per-seat pricing to simplify purchasing for enterprise buyers. The CEO of Legora admits this is suboptimal for the vendor, as high LLM costs from power users can destroy margins. The shift to a more logical consumption-based model is currently blocked by the buyer's operational readiness, not the vendor's preference.
