- Revenue per firm: $240 per year ($20/mo).

Questions
How much money do I need to start?
Enough to talk to buyers and deliver the offer once. A service version can start with a written process and a way to take payment. A software version is a larger bet and is not required to test the price. The band to test is $10–49 a month.
How should I price it?
Test a price between $10 and $49 a month, charged as a free tier and a paid upgrade. Raise it after three paid pilots, not before the first conversation.
Where do the first customers come from?
r/smallbusiness is the clue. A related thread gathered 72 votes and 55 replies. Show up there, follow the room's rules, and ask for conversations. Do not scrape it.
Do I need to write code?
No. The prompts on this page draft a plan and a month of growth. Code is a later choice. The founder site linked once below is where the build document lives, if you want it.
When the business is the software itself, the specification lives on the founder site. Read the agent PRD
A two-week build starts at $10,000 on that site, after a $1,000 scoping fee.
