AI Agents are the new SaaS
A step-by-step playbook for building and selling AI agents as done-for-you labor instead of software seats.
July 1stAn 11-minute whiteboard walk-through of why per-seat software is ending, and the free-tool-plus-paid-intelligence model replacing it.
Because AI makes software cheap to build, the tool should be free, and the money moves to upselling AI agents and human services on top of the data and network effects the free tool collects.
For 15 years SaaS meant paying engineers to build a tool and charging per seat. AI now makes that tool easy to build, so the model is breaking. Isenberg's replacement is smart SaaS: give the tool away free, take data and network effects as payment, then upsell intelligence from AI agents, charged by token or by outcome, and services from humans, charged weekly or monthly. A free calorie tracker that sells personalized meal-plan agents is his example. SMBs and individuals trend toward free, while enterprises still pay something per seat for security and reassurance.

States that SaaS is dead and promises the clearest breakdown of where it is going.

How per-seat SaaS worked for 15 years, the Slack example, and why AI breaks it.

Build the tool, give it away, and take data and network effects as the payment.

Upsell intelligence from agents and services from humans, the idea behind Sequoia's services-as-software thesis.

A free consumer app with paid agents for meal plans and a paid weekly human coach.

Product studio idea, pricing by token, outcome, week or month, and a larger market.

Free trends dominate SMBs and individuals; enterprises still pay per seat for security and comfort.

Asks for engagement and promises a follow-up on niches and opportunities.
When AI makes the tool cheap to build, the paid product shifts from access to the tool toward agents and human services that do the work for the customer.
“Give away the CRM, give away the dashboard, give away the app, get people onto the tool.”
“It's not that SaaS is dead, period. It's SaaS is dead, long live SaaS.”
See every word as it's spoken — crank it to 2× and still catch all of it. The same dual-channel trick behind Amazon's Kindle + Audible.
Greg Isenberg opens with the blunt claim that SaaS is dead, then spends eleven minutes qualifying it into something more useful: the per-seat tool is finished, and a free tool with paid intelligence on top is what comes next.
Old model charges per seat for a tool. New model gives the tool away and charges for agent intelligence and human service on top.
“If this gets 5,000 likes, comments, and subscribes on YouTube, I will go and do more of that.”
A conditional engagement threshold tied to a promised follow-up video.
