Solo Founder AI & SaaS Stack Reference

Curated directory mapping startup functional roles to AI and SaaS tools.

From the Xiry library · Updated 11 October 2026

A reference framework compiled by Greg Isenberg that maps traditional startup roles to modern AI and SaaS tools. It outlines how a single founder can cover functions like engineering, marketing, legal, and sales without hiring dedicated teams. It is a quick guide for solo founders looking to assemble an end-to-end software stack.

The list

everyone is now a startup founder:

- programmer (cursor.ai / replit / claude 3.5)

- designer (v0 / playground / galileo ai)

- product manager (productboard / aha! / airfocus)
