AI enables a fundamental shift in business models away from selling access (per seat) or usage (per token) towards selling results. For example, customer support AI will be priced per resolved ticket. This outcome-based model will become the standard as AI's capabilities for completing specific, measurable tasks improve.

Initial AI market skepticism was based on a SaaS model of selling limited-value subscriptions ('seats'). The new reality is a utility model based on consumption ('tokens'). In an agentic era, a single user can drive thousands of dollars in token usage, creating a virtually uncapped revenue stream that justifies massive infrastructure investment.

The key to explosive AI revenue growth is shifting from per-seat SaaS models to monetizing inference. This "inference waterfall" creates a usage-based revenue stream that removes growth ceilings, enabling companies to scale at unprecedented rates by capturing value directly tied to AI consumption.

The biggest threat to incumbent software companies isn't a new feature, but a business model shift. AI enables outcome-based pricing, which massively favors agile newcomers as incumbents struggle to adapt their entire commercial structure away from seat-based subscriptions.

As AI agents become the primary "users" of sophisticated software, the traditional per-seat licensing model becomes obsolete. Pricing will inevitably shift to a value-based model, tied to outcomes the AI delivers—such as cycle reduction or performance gains—rather than human operators.

Initial AI business models based on per-seat subscriptions ($20-$200/mo) could not justify trillion-dollar infrastructure spends. The market's revenue explosion only occurred after shifting to an agentic, usage-based paradigm, where per-person economics can reach thousands of dollars, unlocking a vastly larger Total Addressable Market (TAM).

Unlike Vertical SaaS which sells software licenses to IT departments, Vertical AI sells outcomes by replacing human labor. This allows it to tap directly into a company's much larger labor P&L, creating a significantly bigger total addressable market and enabling outcome-based pricing models.

As AI agents perform tasks autonomously, the per-seat SaaS model becomes obsolete. The market is shifting to outcome-based pricing (e.g., pay per resolved ticket). There is a massive opportunity for startups to either build new outcome-based solutions or create services that help large, legacy SaaS companies make this difficult transition.

The next major business model shift in software is from seat-based pricing to outcome-based pricing (e.g., paying per task completed). This favors AI-native newcomers, as incumbents will struggle to adapt their GTM and financial models.
