I'm working on a project called https://staywithfounders.com which helps you find awesome people to stay with when you're visiting San Francisco or NYC (more cities to come).
My roommate and I started this because we often had empty rooms in our home and varying luck with Airbnb, but it's quickly grown to tens of houses and travelers in SF and NYC.
It's cheaper than Airbnb, you'll get a private room, and we'll make an effort to match you with a like-minded host.
We're looking for more hosts and guests as we build this out. You can sign up at staywithfounders.com and mention IH in the "Referred by" section, or shoot me a note at firstname.lastname@example.org.
Would also love feedback from the community: is this something you would use? What makes you want to use it, or not?
