For sellers
Stop letting your prompts die in your archive folder.
You built it with Cursor, Claude Code, Codex, Lovable, Bolt, or v0. The deploy works. The login works. You never got to the launch. Someone out there will. Failedups helps you find them.
Building got cheap. Finishing did not.
Two years ago an MVP took six months. Now it takes a weekend. You open a prompt on Saturday morning. By Sunday night you have a working app deployed, with auth, a database, and three of the five flows actually working.
Then Monday comes. The day job kicks in. The launch needs a landing page, a payment flow, a privacy policy, and a hundred small fixes the AI glossed over. You glance at it twice during the week and don't touch it.
By the next weekend you have a new idea and you open a new
prompt. The first project gets a folder named old-app
and waits there forever.
Failedups is the marketplace for the apps the AI built and nobody launched.
From archive folder to handed over
Four steps. No middlemen, no commission, no chasing.
-
Write the candid note
What works. What's broken. Why you stopped. The honest stuff is what buyers actually read. Or skip the form: have your AI coding agent draft the listing for you via MCP.
-
Buyers email you
Your address sits on the listing. They reach out about repo access, monthly costs, user count. No chat layer, no broker.
-
Agree on terms
Price, payment, transfer date. Most deals close in $300 to $5,000, in two or three email threads. We don't touch any of it.
-
Hand off the keys
Repo, domain, hosting, customer accounts. A couple of weeks of light support while they ramp. Then it's theirs.
New: list from your editor
Don't want to fill out a form? Tell your AI to do it.
Failedups ships an MCP server. Add the URL to Claude Code, Cursor, Windsurf, or any other coding agent. Open the project you've been ignoring. Say "list this on Failedups."
Your agent reads the README and package.json, drafts the description, picks the tech stack, and asks you for the few things only you can answer (price, reason for selling, contact email). A draft listing lands in your account, ready to review.
Listings always start as drafts and go through manual review before going live. The agent never publishes without your say-so.

Yes, AI built apps belong here
Some marketplaces sneer at AI built code. We don't. Most of the listings here were built with help from one or more LLMs. Buyers know this. Buyers use the same tools. The question is never "did a human type every line." The question is "does it run, and is the idea worth finishing."
The listings that sell quickest tend to share a few things. A working deploy a buyer can click. A clear note from you on what works and what is broken. The handful of files where the AI made odd choices, called out honestly. Real screenshots, not mockups.
Be the kind of seller you would want to buy from. That's the whole trick.
Tell buyers what they need to know
- Which tool you used to build it. Cursor, Claude Code, Codex, Lovable, Bolt, v0, ChatGPT, Replit Agent. Buyers want to know.
- What works end to end. What is half wired. What is mocked.
- Monthly costs. Vercel, Supabase, the API key the AI told you to add.
- Why you stopped. The single most read part of any listing.
- Repo access on request. A 20 minute walkthrough seals most deals.
Four reasons that hold up
Some money beats no money
A $400 sale is better than the project rotting in a private repo forever. Most listings here close in the $300 to $5,000 range. That covers your AI credits and then some. The code was about to get deleted anyway.
Closure is underrated
Knowing the project lives on with someone who has the time to ship it feels different than 'maybe I will come back to it' for the eighteenth time. You get to actually move on to the next prompt.
Honest beats polished
Buyers respect plain truth. 'I lost interest' is fine. 'I built this in a weekend with Lovable and never deployed it' is fine. We do not push you to spin a story about momentum that did not happen.
We never take a cut
The price is between you and the buyer. We do not touch the sale itself. The only thing we charge for is optional boosts, and those are flat fees, not a percentage.
Free to list. One upgrade if you want more eyes.
We make money on this and only on this. One package, all the visibility features. One-time payment, no subscription.

Selling a startup: common questions
Anything else, email hello@failedups.com.
- Where can I sell a half built SaaS startup or side project?
- Failedups is a marketplace built for exactly this — startups, MVPs, and side projects you are not going to finish. Listing is free, there is no commission on sales, and you talk to buyers directly. You publish a listing, buyers email you from the page, you agree on terms, and you transfer the assets. Most listings close in the $300 to $5,000 range.
- How much can I sell an unfinished startup or MVP for?
- Most unfinished startups sell between $300 and $5,000. AI built MVPs without users land at the lower end. Hand crafted SaaS with paying customers tends to go higher — $5,000 to $25,000 is common. The real anchor is what the project is worth to a builder who has the time to ship it. Honest founders who price reasonably usually close within a few weeks.
- Can I sell an app I built with Lovable, Cursor, Claude Code, Codex, Bolt, or v0?
- Yes, and it is encouraged. Most listings on Failedups are AI built. Buyers know this and use the same tools. The only thing we ask is that you say which tool you used, what works end to end, and what is still half wired. Being upfront speeds up the sale because buyers can plan how to finish it with the same AI.
- Is it better to sell a startup outright or look for a cofounder?
- Depends on whether you want closure or skin in the game. If you are done and want the project off your plate, sell it outright — most deals on Failedups are sales. If you still believe in the idea but cannot finish it alone, list as a cofounder search instead. No asking price, equity-only deal between you and the partner. Both options are free to list.
- Do I need a contract or lawyer to sell a small startup?
- For sales above a few thousand dollars, you should have something signed. A one-page asset purchase agreement is enough for most sub-$10k deals. Stripe Atlas and Clerky publish free templates that work for small acquisitions. We do not give legal advice, but we recommend a written agreement covering what is being transferred (repo, domain, accounts) and what is not.
- How long does it take to sell a side project?
- A well-written listing with a working deploy and an honest founder note typically gets first inquiries within a week. Most deals close in two to four weeks. Boosting a listing — paid feature placement on the home page and at the top of the browse page — usually halves that. Listings with vague descriptions or no deploy tend to sit.
- How do I write a good listing for an unfinished startup?
- Five things buyers want: which tool you used to build it (Cursor, Claude Code, Codex, Lovable, Bolt, v0), what works end to end versus what is mocked, monthly running costs, why you stopped, and a working deploy URL. Honest beats polished — 'I lost interest' is a fine reason. Buyers respect plain truth and most close on listings where the founder did not oversell.
- Does Failedups take a commission on the sale?
- No. Listing is free and we never touch the buyer-seller transaction. The price you agree on is the price you take. The only thing we charge for is an optional one-time boost if you want extra visibility on a specific listing — flat fee, no subscription, no percentage.
The hardest part is admitting you're done.
The rest is just typing, or not even that. Fill out the form, or let your AI agent draft the listing for you over MCP.
