AI Agents Are Making Salesforce More Valuable and Killing Notion. The SaaS Stack Is Splitting in Half.

SaaStr published production data from running 20+ AI agents that should make every SaaS founder rethink their product category. Their Salesforce bill went up 80%, from roughly $16K to $22K per year, despite cutting human seats by 60-70%. Meanwhile, Notion usage dropped to literally zero daily active users. Nobody canceled. They just stopped opening it.

The pattern is clean and it's showing up everywhere. Agents use CRM 100x more than humans ever did, hammering APIs and running data operations around the clock. But agents have zero reason to open a collaboration UI designed for humans. Notion, project boards, wikis built for eyeballs. They become invisible.

This isn't just SaaStr's experience. Salesforce's Agentforce hit $800M ARR with 2.4 billion tasks completed in Q4 alone. They're now billing in "Agentic Work Units" instead of seats. Vanta crossed $300M ARR (up 69% YoY) because compliance infrastructure, the stuff that tracks and governs, thrives when agents multiply data access and risk surface.

Oliver Wyman put out a framework that PE firms are already using to triage portfolios: three core SaaS valuation assumptions have broken. Software isn't hard to build anymore. Seat expansion doesn't drive revenue. UI familiarity doesn't create moats. They recommend sorting holdings into "Resilient," "Reinforce," and "Structural Disruption Risk" tiers. That last tier is a polite way of saying "sell before the market figures it out."

The emerging rule is simple. If your product is a system of record, a data store, a governance layer, agents make you more valuable. If your product exists primarily as a human collaboration interface, you're facing what SaaStr calls "stealth churn." Nobody cancels. The usage just evaporates.

I'm building solo, so I feel this acutely. My agents hit databases and APIs constantly. They never open a wiki. If you're building SaaS, ask yourself: does an agent need my product to do its job, or does my product only work when a human is staring at it? That answer determines your next five years.
