Agentic SaaS Playbook 2026

For a long time, I was looking for serious resources on building agentic products, resources for people who actually want to ship products that work and loved by users. I paid for courses, books, communities, and programs hoping one of them would go deep enough.

A lot of courses, books or content show you a clever workflow, maybe a framework, and then quietly skip the hard parts: identity, permissions, billing, retries, monitoring, data ownership, and the boring realities of operating software for customers.

And that gap is where most of the real work lives.

Users will stress-test your edge cases, your costs, your uptime, and your trust boundaries, and they will hold you accountable.

That's the part I needed help with when I started.
That's the part I couldn’t find.
So that's the book I wrote.

If you follow the sections at your own pace and build alongside the repository, you'll understand what it takes to design, implement, and operate a SaaS product with agentic capabilities.

You'll build a Deep Research Agent that runs inside a real SaaS product: a public landing page, SEO optimized blog, a protected workspace, billing, recurring automation, and a backend that enforces identity and ownership, something you can actually put in front of customers.

Throughout the book, I'll use planes as a practical way to reason about the system: UX, orchestration, runtime, memory, data, integrations, security, and observability.

Each plane is where specific failure modes show up, and where specific investments pay off.

Here's what you'll end up with:

• A public SaaS surface (landing, docs, pricing) that transitions cleanly into a protected workspace.
• A protected product area where users launch runs, approve steps, ask follow-ups, and download reports.
• A full run lifecycle: search → collect sources → summarize → approval gates → memory indexing → PDF report.
• Monitors that schedule recurring research runs like a lightweight operations layer.
• Stripe-based entitlement gating so runtime access is enforced server-side, not just in the UI.
• A mock vs live mode switch so you can demo and test fast without breaking production contracts.

This book, and the assets that come with it are for people building a product that works, that people trust and that lasts.

I hope you enjoy the freely available sections and deep dives. They're not light previews, they're genuinely substantial, and I put as much emphasis on them as I did on the gated sections. They're absolutely worth studying and practicing.

And if you're serious to take things a lot further, then I'd love for you to join The Agent Foundry. It's an exclusive membership for builders who want to ship products the right way, with depth and discipline. I hope to see you inside.
