Summary
Greg Isenberg argues that traditional SaaS, built on per-seat pricing for human-operated tools, is being upended by AI models capable enough to make building software cheap and fast. Citing the latest generation of frontier models, he explains why the old playbook that produced multibillion-dollar outcomes like Slack’s $29 billion sale no longer holds.
In its place, Isenberg describes what he calls SaaS 2.0 or “smart SaaS.” The tool itself, whether a CRM, a dashboard, or a niche app, is given away free. Users pay with data, which builds network effects and a proprietary-data moat. Revenue comes from upselling intelligence, meaning AI agents that perform tasks inside the product, and from human-delivered services layered on top. He ties this to Sequoia’s idea that services are the new software.
A consumer example, a free calorie-tracking app that charges for agent-generated meal plans and a human weight coach, makes the model concrete. The video closes by pointing to niches where old paid tools can be replaced by free alternatives, and is aimed at founders and indie builders looking at where software businesses are heading.
