Describe the business you want. We'll find the listings.

MainStreetKeys is a chat-style search over businesses for sale. You write what you're looking for in plain English, such as price, profit, business type or state, and it turns that into filters and shows the matching listings. Every result links to the broker that published it.

Where the listings come from

Right now the catalog has 536 current listings gathered from the public websites of QuietLight, Empire Flippers, Accounting Practice Sales and Simmons & Associates. That covers online businesses (SaaS, ecommerce, Amazon FBA, content sites and more) plus accounting and veterinary practices. Listings are refreshed daily. We show the figures the broker published and don't copy descriptions or images.

MainStreetKeys is not a broker and isn't affiliated with these brokers. We don't verify listings, so always check the broker's page and do your own due diligence.

A note from the founder

I acquired my first business in Jan 2026, but it was really painful to source and find it. Businesses for sale are spread across many broker sites, with their own filters, nothing really gets saved very well, and don't get me started on the spam emails after signing up! I built MainStreetKeys to aggregate businesses for sale, inside a native chatbot function where you can simply describe what you are looking for.

If something looks wrong, a listing is out of date, or you'd like a source added, email me at hello@respondpal.ai. We are still early and adding sources and features as we go.
