Linked In aside, social media isn't typically associated with the professional sphere, but Bottleshake is a new social media platform that is specifically designed for use by professionals. However, unlike with Linked In (or any other social media platform for that matter), Bottleshake's entire raison d'etre is to get people offline. The app helps engender networking meetings between professionals in the real world, allowing people to build their name in the given industry.
With Bottleshake, professionals set up coffee meetings, called "shakes" in the app, at locations near them. Other users can sort through the various shakes to find a meeting that aligns with their industry, and the shake creator has the option of accepting or rejecting everyone who joins in.
