You don’t prompt it.
It interviews you.
Custom business software for small businesses, planned through a conversation and proven with a working demo before production begins.
Neighbors used to raise a barn in a day, everyone lending a hand. Raise your app the same way. BarnBuilder interviews you, writes you a plan you approve, and builds a demo in your own colors. When it is right, Emile helps you make it real.
Free to interview, get a proposal, and build a demo. No credit card.
From a conversation to a live product
The same order a good consultant would follow, turned into a guided product. Trust artifacts, one after another.
- 1
Interview
We ask the questions a good consultant would, one at a time, in plain language. You talk, we listen.
- 2
A proposal you approve
You get a written plan with concrete promises. Nothing is built until you say yes, and one change is on the house, reworked to your words.
- 3
Your brand extracted
We pull your real colors and voice, so your app never looks like a generic template.
- 4
A demo you can share
A working, mock-data demo of exactly what we promised. Play with it on your phone before you pay a cent.

Launch it with Emile
Your approved demo becomes the production plan. Emile connects your real data, confirms sign-in, handles the parts that need a person, and launches the first release with you.
Honest by design
Prompt-first tools hand you a blank box and a credit meter. BarnBuilder hands you a conversation and a written plan.
No blank prompt box
You never stare at an empty box wondering what to type. We interview you.
A written plan first
You approve a plain-language proposal before anything is built.
No credits, ever
Nothing to buy or burn. Every plan covers an included amount of outside-service cost each month; anything past it is passed through at cost plus 20 percent, itemized in dollars.
Prices in dollars
Simple monthly plans you can read, not tokens you have to translate.
Emile leads your launch, personally
We are taking a small first group of small businesses into BarnBuilder. Emile reviews every proposal and leads every founding launch himself, so each application is read for fit before it is accepted.
- A production-fit conversation, and a written launch scope you approve before anything starts
- Up to 10 hours of Emile's hands-on time to build and launch that agreed first release
- Your first 30 days live at no charge, credited once the real app is yours to use, not while it is still being built
- Your Real plan then continues at the locked founding rate of $69 a month, against a standard $99
Where the line sits
The included time delivers the first release you approved, not an open list. If something new would take us past it, you get a written estimate first, and nothing billable begins until you say yes. Extra work is $60 an hour or a fixed price agreed up front.
Why the group is small
The limit is Emile's own calendar. He reviews each proposal and runs each launch, so the number of founding spots is the number he can serve well.
18 of 20 spots open
2 of the 20 places are already spoken for, which is why the count starts where it does.
Founding builders give us candid feedback while we get this right. After a good launch we may ask to tell the story together, with your approval. A kind word is never a condition of your rate.
Start with the free interview and demo. Founding spots are offered after Emile has read your proposal and talked production fit with you.
Simple plans, in dollars
The interview, your proposal, and a demo build are free. Keep it live, add AI, or make it real when you are ready.

- The first $20 of usage covered each month
Your plan keeps the app you approved running and supported. New features, integrations, and larger changes are planned and priced separately, and never started without your written go-ahead.
Heavy usage is passed through at cost plus 20 percent, itemized in dollars on your invoice. No credits, ever.
Heavy usage means outside services your app consumes on your behalf, such as AI beyond your plan's included features, text messages, or bulk email. Every plan covers an included amount of that raw cost each calendar month: $5 on Free and Demo, $10 on Live, $20 on Real. Anything above your plan's allowance appears on your invoice at cost plus 20 percent, listed line by line in dollars. Under it, it is simply covered by your plan.
