Building and launching alone
What can AI agents do in a one-person business?
Cal Renshaw, , 2 minute read
AI agents are excellent at labour: work where you can say what a right answer looks like before you see it. Reading a pile of documents, turning a rambling voice note into a list, drafting a reply for you to edit. They're poor at judgement, and when you hand them a decision, what comes back reads exactly like one and is actually the average of everybody else's.
The labour
Every product I've built since my sixth year has had a machine doing some of the work. The document product reads, every month, a pile of documents somebody used to type up by hand. A voice-notes tool turned tradespeople's recordings into written quotes. Both worked, because both were labour with a check in front of it: in the quotes tool, ordinary code confirmed every number in the quote appeared in the voice note.
The judgement
In my sixth year I built a membership-renewal tool for small clubs almost entirely by asking a model what a product like it should have, cost and do. Every answer was fluent and organised. I accepted all of them.
The result was the average of the 4 decent tools already in that category. 6 weeks after launch a customer asked why the settings offered a weekly digest, and I had no idea, because I'd never decided it. Nobody had. It closed 5 months later.
The line I draw now
Use the model for research, never as your mouthpiece. It reads competitors' pages faster than I can and summarises what customers complain about. Then I close the window and decide, with a pencil.
As a mouthpiece it's dangerous, because what it says goes out in your name. A price, a promise, an answer to a customer about their data. Those need a fixed answer you wrote, a check in code, or you.
A simple test
Before handing a job to an agent, ask: could I write down the right answer as a rule before I see the result? If yes, it's labour, and a machine can do it with a check. If no, it's judgement, and it stays yours.

Questions
- Can an AI agent run a business for you?
- It can do much of the labour: reading, sorting, drafting. It can't decide what the product is for, what it costs or what to say when it goes wrong. Those stay with you.
- What should a solo founder automate with AI first?
- The repetitive reading and drafting that eats your evenings, with a check in front of anything a customer will see.
- Is it risky to let AI answer customers?
- Yes, for anything about money, dates or their own data. Give the model a short list of questions it may answer with your own written answers, and send everything else to you.
