Nine of the Top Ten AI CompaniesNarrow moat

Salesforce (CRM) — moat facet

Salesforce says nine of the ten largest AI companies run on it, with CRM seats up 62% a year: the firms best placed to replace packaged CRM are buying more of it.

The customers most able to replace Salesforce are, on the company's own figures, buying more. Its Investor Day said "9 of the top 10 AI companies are building and betting their future on Salesforce"1, measured against the Forbes list of the top 50 AI companies. The same slide claimed "62% YoY CRM Seat Growth" among the top AI sales and service teams, "100% Slack Adoption" and "+435% YoY ARR Growth" for the cohort2.

The would-be disruptors are buying.

These are management's figures, chosen for a presentation, and Salesforce does not name the companies or give dollar amounts. But they carry a point the rest of the evidence lacks. If the businesses building AI agents were going to abandon packaged CRM, they would be the first; instead their seat counts are rising.

The same deck describes how large customers expand. A customer at the "Agentic" stage "Adopts Agentforce in support and core expansion, with some seat optimization", with an ARR uplift of 1.5 to 2 times3. Seats may fall while total spending rises, if the agents are bought from Salesforce.

There is a concentration risk hidden in the success. AI companies are young, fast-growing and heavily funded; their spending can fall as quickly as it rose. Salesforce's revenue concentration remains low, with no customer at a tenth4.

The deck also claims a wider effect: ">2x ARR uplift in 18 months since Agentforce launch"5 among customers adopting agents. The figure is unaudited and the cohort is chosen by the company; it is evidence of direction, not of size.

The claim is testable only at the next Investor Day. If Salesforce stops reporting the AI-cohort figures, or the cohort's growth falls below that of its other customers, the companies best placed to judge will have changed their minds.

Moat trajectory: Widening

AI cohort ARR +435% year on year, per the company.

Whether the most AI-capable customers keep buying seats; a decline would be the first sign of replacement.
