Idea: Multi marketplaces inventory sync
The app allows you to sync items you sell in the real-time between Etsy, Shopify, Amazon, etc.
I'm sure there are people/businesses who sell some/tremendous amounts of something on a multiple marketplaces. There are should be some solutions, or some businesses try to build the solution by themselves because of their specific needs that current market solutions don't provide or do so poorly.
