In a beautiful campaign, Airbnb brings people closer by giving its members 1 million dollars to go towards making someone happy. The concept behind it is that people upload their stories and hastag it #onelessstranger. The thinking behind the concept is brilliant. Airbnb is a brand that is all about connecting strangers and letting them live in your homes. From its humble beginnings of renting out air mattresses to now where visitors can rent even a castle, Airbnb has kept true to its brand ethos of bringing perfect strangers together.
