Industry playbook

How AI is running SaaS startups.

Startups have always been forced to do more with less; AI just amplifies that. The 5-person SaaS in 2026 is doing what a 25-person team did in 2022 — but only if the founders push aggressively into agent-driven workflows.

Common pitfalls

Don't replace product judgment with AI — keep humans on the strategic calls.
Cheap AI tools at small scale get expensive fast as you grow.
Hiring decisions should still be human, especially for early roles.
