Build a marketplace
Stand up both sides of the market — listings, discovery, and a brand that earns trust.
Press Enter to start building this one, or describe your own.
The first build
What exists at the end of the first session
- A marketplace site with listings, categories, and detail pages
- Seller and buyer-facing pages that explain how it works
- Brand, copy, and design that make a two-sided pitch credible
- A live URL for recruiting your first supply
Before you scale it
What a first version has to settle
Both sides on one page
A visitor should see who sells and who buys within a screen. If the pitch needs explaining, the market isn’t drawn tightly enough.
A niche you can name
One city, one category, one kind of seller. Describe that in your prompt and the listings, categories, and copy follow it.
Supply before plumbing
Real transactions come later. First get sellers to say yes to somewhere they’d be glad to be listed.
Beyond the build
A product is not a company
The site is the part you can see. These are the four other jobs a marketplace needs, and what Restart hands you for each.
Positioning brief
Brand
One promise that reads to both sides at once — worth listing on, worth buying from — without hedging either.
Seller recruitment pages
Launch
A page that pitches sellers on being early, and a launch page for the city you are opening in.
Buyer and seller flows
Customers
Sign-up, listing, and enquiry flows, so interest from either side has somewhere to land the same day.
Internal tools
Operations
A review queue for new listings and a way to see what is live — the part that keeps a market trustworthy.
Questions founders ask
Does it handle real transactions?
The first build presents your marketplace with demo data — perfect for validating supply and demand. Real payments come as your company grows.
What should my first version prove?
That both sides want in. A credible site with real listings language lets you pitch sellers and gauge buyer interest before you invest in transaction plumbing.
Can I start with one city or niche?
That’s usually the right move — describe the niche in your prompt and the Builder shapes the copy, categories, and examples around it.
