The seasons are changing, and synergy is in the air: Airbnb's founder Brian Chesky is using his girlfriend's app as a platform to share their love—and his unofficial corporate slogan.

It's unclear what occasion called for the flowers and a stay in what looks like a perfectly manicured Airbnb property. But nothing makes a memory like "fuck hotels"—a sentiment someone has been floating recently on Secret, too.

Modern love: branded, on-demand, social, and mobile-first.
