Try signing up! You can create a new listing, search existing ones, send messages to other users, and view upcoming trips. It's integrated to Stripe as well so you can actually book a trip (although I wouldn't recommend that since every listing is fictional).
I get zero results for every search I try. EDIT : I think because I was searching outside of San Fran (looks like there are only 6 properties there, probably for your testing)
Either the site is super buggy or my browser is just barfing everywhere. Most photos don't load.
I think I'm getting the point now though - this seems like a GREAT way to provide proof of concept!
