SaaS is minting millionaires again (here's how)

I walk through a complete 30-step playbook for building a modern SaaS company using AI agents, media, and sub-niche positioning. The core argument is that SaaS is evolving rather than dying, and the builders who win are the ones who combine a focused workflow product with a media flywheel and agent-powered execution. Drawing on my experience advising TikTok, Reddit, and building three venture-backed companies, I lay out a step-by-step framework any solo builder or small team can follow from niche selection through to becoming the default execution layer in their market. I'm hosting a free workshop so you can build your business in the age of AI.

Numbered Section Summaries 1. Sub-Niche: This the best moment in history to build SaaS because the cost to build, distribute, and sell is at an all-time low. The first move is picking a sub-niche inside a large market. Going narrow keeps indie builders out of direct competition with venture-backed players and makes cash flow achievable. 2. Workflow Mapping and Money Identification: Mapping a niche operator's full daily workflow end to end, then highlighting exactly where money changes hands. Using a local roofing company as the example, I walk through how to do this manually, through operator interviews, or with AI tools like Manus and Claude Code. This becomes the product roadmap. 3. Content and Audience Building: Building media in parallel with product is the unfair advantage. I describe using AI to generate content ideas, scripts, and scheduling — while personally tracking Instagram insights to develop content intuition. Organic content that earns saves and DMs becomes the creative brief for paid ads. The email list is the foundation that outlasts any algorithm. 4. From Manual Service to Agent Automation: The operational core of the playbook. Starting by manually performing the workflow builds the understanding needed to automate it precisely. I emphasize separating mechanical tasks (where AI excels) from judgment tasks, then converting the mechanical ones into agent workflows connected to real tools — email, Slack, CRM, Stripe — using MCP integrations. 5. Compounding Into the Default Execution Layer: The compounding value through deeper workflows and more data, expanding into adjacent workflows, building switching costs through memory and user preferences, turning power users into filmed case studies with paid distribution, hiring operators from inside the niche, and reinvesting in content and product depth until the product becomes the default execution layer for the sub-niche.
