About KeyNest
About
KeyNest was founded in 2016 by two Airbnb hosts, Marc and Florian. Marc was getting fed up with changing his plans to meet Airbnb guests who were arriving late, so he asked his local cafe to hold the keys for him - and that’s when KeyNest was born.
Now our network of points holds and hands over the keys for thousands of people across 12 countries, and we provide KeyNest Pro, a smart key tracking software for estate agents.
