Your City Posts This Online Every Day. Use AI to Sell It.
Chris Koerner builds a daily building permit alert app for contractors in under an hour using AI, then tries to sell it live. His hook: cities post permit data free every day, and contractors will pay to see it first.
The gist
-
Koerner's plan is to charge contractors $99 a month for daily permit emails, so 20 contractors brings in $2,000 a month.
-
He names five trades that buy these leads: landscapers, gutter companies, blinds and shutters, pool builders, and fence companies.
-
He builds the app with an AI agent, using Stripe for payments and Resend for emails, then switches from Dallas to Chicago when Dallas data was blocked.
-
He buys a custom domain on Namecheap and connects it without editing DNS records, with a total cost of $5.67 in credits plus $11.
-
His outreach offers a free list, then $99 a month with a full refund if no lead lands in 30 days.
