For founders Updated
Can an AI build your startup?
Yes. An AI startup builder takes a startup idea written in plain language and turns it into a working first product you can publish and put in front of customers, usually within a session. Restart does this and also produces the brand, launch pages, pricing and operating tools a startup needs around the product.
Press Enter to start building this one, or describe your own.
What do you get back?
You type the idea in a sentence or two. Restart asks the one or two questions that change the build, then the Builder writes the pages, the copy and the design while you watch. At the end of the first session you have:
- A working web product: real pages, real flows, design you would show an investor or a customer
- A live URL the moment you publish, so a pitch becomes a demo
- A positioning brief, a launch page, and pricing laid out so a stranger can pick a plan
- A company inbox with its own address, a daily list of suggested tasks, and research with sources
- A workspace where every change is a sentence: ask, review the live preview, re-publish
What still needs you?
An AI startup builder removes the engineering gap between an idea and a product. It does not remove the founder. The parts that stay yours:
- Talking to customers and deciding what they actually pay for
- Choosing the one workflow the first version must do better than a spreadsheet
- Incorporating, banking and taxes: Restart does not form a legal entity
- Payments, user accounts and integrations inside the product, which come after the first build
The honest test of a first version is whether a stranger understands it in one read and whether you can send it to someone today. Restart is built to get you to that test in a session.
What does it cost?
| Way to build a first version | Typical cost | Typical time | What you own |
|---|---|---|---|
| Agency or dev shop | $10,000 to $100,000+ | 6 to 16 weeks | Code, once the invoice is paid |
| Freelancer | $3,000 to $20,000 | 4 to 10 weeks | Code, per the contract |
| Technical cofounder | Equity, often 20 to 50% | Months to find, then weeks | Shared |
| No-code tools | $30 to $150 a month | 2 to 6 weeks of your time | A project inside the tool |
| Restart | Free to start; Pro $20 a month | One session | Everything you create |
Agency, freelancer and cofounder figures are typical ranges as of September 2026, not quotes. Restart pricing is on the pricing page.

Questions founders ask
Can an AI actually build my startup?
It can build the first product, the pages and the launch material, and publish them to a live URL. On Restart that happens in front of you with a live preview. What it cannot do is find your customers or make the judgment calls; those stay with you.
How long does it take to build a startup with AI?
A first working version takes one session on Restart: describe the idea, answer a couple of questions, watch the Builder create it, publish. Founders then spend days, not months, iterating on what customers say.
How much does it cost to build a startup with an AI startup builder?
On Restart the first company is free: 5 build credits a day and no card. Pro is $99 a month and Autonomous starts at $399, each with a monthly credit pool. Compare that with the $10,000 to $100,000 an agency typically quotes for a first version.
Do I need a technical cofounder?
Not to get to a working first version. You describe the product in plain language and the Builder writes the code. Many founders bring on an engineer later, once there are paying customers and a clear thing to scale.
Can AI generate startup ideas as well as build them?
Yes. Type "Generate a company idea for me and start building it" at restart.new/new and Restart proposes one and begins. Most founders arrive with their own idea; the builder sharpens it before building.
What is the difference between an AI startup builder and an AI app builder?
An AI app builder produces software. An AI startup builder produces the software and the rest of a first company: positioning, launch pages, pricing, an inbox, tasks and research. Restart calls this an AI company builder.
