ConceptMRR

ConceptMRR sells ready-built software startups. Each of the 282 listings is modelled on a real business whose monthly revenue is verified through Stripe on TrustMRR, so you start with a type of product people already pay for instead of guessing.

You get the full source code, documentation, the domain and a 90-day launch playbook, delivered in 1–2 weeks with a recorded code walkthrough and full IP assignment. Each startup is sold to one buyer only. Prices run from $2,400 to $11,900, paid once.

It's a new product: there are no customers or revenue included, and the comparable's revenue isn't yours. If it isn't delivered within 14 days, you get a full refund.
