Vouch for the people
you've lived with
Karl and Ben is a simple social network that allows people to vouch for friends or acquaintances they have lived in the same house, whether that was for a few days or multiple years.
The question we keep asking
Lots of our friends move between London and San Francisco. We want to help them and we want to host them. Inviting someone you don't know can be risky. We want a simple way to ask:
"Does any of my friends know this person? I'd love to invite them to my house but I'm a bit afraid to invite a stranger."
"Do I know anyone in London/San Francisco? I'm going there for two weeks and I'd love to stay with someone who I have some connection to."
