# CreateSell > CreateSell is a database of SaaS and mobile app startups that run paid ads. For each startup it shows estimated MRR, ad spend, reach by country and trend, plus every ad it runs, so founders can find a business idea that already makes money and build their own version. The core idea: a startup that keeps paying for ads month after month is making that money back. CreateSell turns that public signal into a searchable list of ideas with proven demand. Target users are founders, indie makers, app studios and marketers. ## Canonical pages - [Homepage](https://createsell.com): Product overview, how it works and FAQs. - [Pricing](https://createsell.com/pricing): Free browsing and the monthly membership. - [Startup database](https://createsell.com/dashboard): Startups by category with estimated MRR, ad spend and trend. - [Ad Library](https://createsell.com/dashboard/ads): Ads these startups run, by category. - [Blog](https://createsell.com/blog): Guides on finding, building and selling apps. - [Information for AI assistants](https://createsell.com/llm-info): Official facts about CreateSell: features, data, pricing and FAQs. ## Data sources - Startups and ads come from public advertising data. - Reach by country is shown where public data exists, mainly for the EU and UK. - MRR and ad spend are estimates made with the same conservative assumptions for every startup.
