StartIUP turns an idea into a real, working startup prototype. Type an idea name and a short description. The Idea Computer runs for about two hours, on our servers, and delivers a hosted demo, the source files, UX files and a technical build spec. No chat. No prompting. No wasted credits.
Each stage hands a finished file to the next. Times are estimates, never promises. The whole run is about two hours.

Business thinking stays private. It helps the later stages agree with each other. It is never shown, sold or offered for download, and you never see it on screen or in your files.
What you get
Real files you own from day one.
Everything arrives in one place, and in a done email with the links.
01Hosted demo. A live prototype at its own address, free for 7 days.
02App source files. The full app as one download.
03UX and brand files. Design and landing concept.
04Technical build spec. Ready for Cursor, Lovable, Claude Code or a developer.
+Next-step prompt. Takes the prototype to production, round by round.
Honest note. This is a prototype. Small faults, like a missing logo or a rough edge, are normal. Use the build spec and the next-step prompt to take it further. Builds are made by AI, and free demos carry the footer credit "Designed and built by startiup.com".

credits per build · 1 credit = $1
Credits are reserved when a build starts, spent only when it finishes, and returned automatically if it fails. Credits do not expire. There are no subscriptions. Premium hosting is 10 credits for 365 days, with the footer credit removed.
No. There is no chat, no prompting and no back-and-forth. You type two things: an idea name and a short description. The Idea Computer does the rest.
How long does it take, and do I have to wait?
About two hours. It is an estimate, not a promise. The build runs on our servers, so you can close the tab or switch off. We email you when it is done.
What if the build fails?
Your 69 credits are returned automatically and we email you to say so. You can retry with the same name and description.
Who owns what I get?
You do, from day one. Every file downloads. StartIUP does not host production apps, run payments for your app or hold your customers.
Is the prototype finished?
It is a prototype. Small faults, like a missing logo or a broken function, are normal. The build spec and the next-step prompt help you take it further in Cursor, Lovable, Claude Code or with a developer.
What happens after 7 days?
The demo address shows "this demo has ended", and your files stay downloadable. Premium hosting is 10 credits for 365 days and removes the footer credit. We email you 2 days before and on the day.
