The new generation of AI automates workflows, acting as "teammates" for employees. This creates entirely new, greenfield markets focused on productivity gains for every individual, representing a TAM potentially 10x larger than the previous SaaS era, which focused on replacing existing systems of record.

The explosive growth of AI applications like ElevenLabs is driven by a step-function change in value. They replace processes that cost thousands of dollars and weeks of time with a solution that costs $30 and takes 10 minutes. This massive ROI compression makes adoption a no-brainer for customers.

Companies like Sierra can't justify a 100x ARR valuation by targeting the existing software market (e.g., $8B Service Cloud). The bet is that they will capture a significant portion of the much larger human labor market ($200B+ for support agents). This represents a fundamental transition of spend from human capital to software.

Satya Nadella suggests a fundamental shift in enterprise software monetization. As autonomous AI agents become prevalent, the value unit will move from the human user ("per seat") to the AI itself. "Agents are the new seats," signaling a future where companies pay for automated tasks and outcomes, not just software access for employees.

Enterprise software budgets are growing, but the money is being reallocated. CIOs are forced to cut functional, "good-to-have" apps to pay for price increases from core vendors and to fund new AI tools. This means even happy customers of non-mission-critical software may churn as budgets are redirected to top priorities.

Historically, labor costs dwarfed software spending. As AI automates tasks, software budgets will balloon, turning into a primary corporate expense. This forces CFOs to scrutinize software ROI with the same rigor they once applied only to their workforce.

Unlike SaaS which sells to limited software budgets (e.g., 1% of revenue), vertical AI agents automate core business functions. This allows them to tap into much larger operational and labor budgets. Companies can capture 4-10% of a customer's total spend by replacing expensive human-led tasks like customer support.

The paradigm shift with AI agents is from "tools to click buttons in" (like CRMs) to autonomous systems that work for you in the background. This is a new form of productivity, akin to delegating tasks to a team member rather than just using a better tool yourself.

Unlike traditional software that supports workflows, AI can execute them. This shifts the value proposition from optimizing IT budgets to replacing entire labor functions, massively expanding the total addressable market for software companies.
