About this collection

This is the searchable companion to The Strategy Stack's One-Person AI Operating System guide on Substack. Use it when you need a tool for a specific solo-business function—not another disconnected app list. Filter by stack category, cost, and format. Each entry links to the provider and summarizes how it fits a one-person operating model. Start with AI assistants and knowledge management, then connect automation, marketing, CRM, delivery, and finance as your workflows mature. For the seven operating components, twelve workflows, and 14-day roadmap, read the field guide on Substack (linked on this page).
