Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Manual Cross-Platform Listing

Resellers waste hours manually creating, syncing, and delisting the same inventory across multiple marketplaces, causing errors and lost sales.

In their words

Required attributes that are entered correctly in Seller Central but don't appear on the live listing

It eats hours and I still end up with duds half the time.

r/dropshipping on Reddit

It makes duplicate listings... I have to manually go through, and move the ebay listing over to the right row.

r/eBaySellers on Reddit

r/whatnotapp on Reddit

they tried to send me to a scam customer service number when the "venmo didn't go through"

r/ScrapMetal on Reddit

I contacted eBay and asked whether duplicate listing is allowed, they answered that it is against their rule but when I sent the profile of this seller, they wrote me that everything is completely fine

r/Ebay on Reddit

If you made a squarespace plugin or otherwise that would index someone's store, then that store owner would be able to get business from the shared platform, while not worrying about having a good search tool.
