Vertical SaaS: one agent for one profession at $99–$999 a seat
The biggest revenue pattern for solo agent builders is vertical SaaS: pick one workflow inside one profession, automate about 80% of it with a small agent, and charge $99–$999 a month per seat. Market examples run from accounting copilots at $400 a month per accountant to legal research tools at $200–$600 a month per lawyer. No processor-verified revenue backs this pattern in the source — only market pricing.
