Ask HN: Thoughts on a network for founders/creators to iterate on products?

I'm thinking about creating a network that lets founders test products on one another. As a network of founders we'd help UX test for each other, generally network and hop on video calls. Other founders are typically going to be your first users too so I think some interesting connections could happen here and product directions could change and become stronger as a result of more communication/feedback.

Lurking wouldn't be allowed on this network, and to get people to help you need to be helping others as well. I made a landing page - https://founderfoundry.carrd.co/ if you're interested or think others might be please share it out!

Would you like a community like this? What rules would be useful? How do we fight spamminess and make it genuine? Do you feel that the networks that already exist get the job done already?
