## Summary

A focused playbook for building one narrow, excellent AI agent — and the business that surrounds it.

## Synopsis

The temptation with agents is breadth. Ethan Mercer makes the case for the opposite: one profitable problem, solved completely.

The book walks the full arc — problem discovery, agent design, evaluation harness, pricing, onboarding, and the retention work nobody posts about.

It is deliberately unromantic about revenue: real numbers, real churn, and the month where nothing worked.

## What you will learn

- Find a problem expensive enough to pay for automation
- Scope one agent narrowly enough to be reliably excellent
- Price on outcome value rather than token cost
- Instrument the agent so failures reach you before they reach the customer

## Who it is for

- Technical founders looking for a first AI product
- Agency owners productising a service
- Operators who want recurring revenue without a large team
