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.
