potential co-founders

I met a guy on the co-founder matching platform last week, and we are moving forward with discussions.

His basic idea is to build a social shopping app, where you can share your purchases with your friends, and see what they are buying.

So my 3 primary questions are:

• Do people want to see their historical purchases?
• Do people want to share (some of) their purchases with their friends?
• Do people want to see their friends’ purchases?

If the answer to any of these questions is yes then the idea might have legs.
