Ask HN: [Validating app idea] An app which allows you to hoist a private auction
I have an idea for an app and I am trying to validate the idea. I want to create an app which allows users to hoist a private auction (an English Auction). You create an auction in my app, keep some start time for the auction, you invite other users to participate in your auction by mentioning their email addresses. The auction happens and the highest bidder is decided. The actual transaction between the highest bidder and seller happens offline. (May be in some other use cases, there is no actual transaction)
@HNs: 1) Will you be needing this app? If so, what is your case? (if the use case is shady, just mention shady) 2) I am having trouble in figuring out the use cases. Can you guess any use cases for this app?
Edit: Only the users invited to the auction will be able to bid.
