When there's a live-in Pomeranian named Tommy in the office full time—of course your office is cool. Although it's a big space, there's no labyrinth-like floor plan that makes it difficult to find the kitchen. To add to the homey, lived in feel, the fridge is covered in fan mail, the walls are decorated with art created by tumblr users, and the employees dine together at a large wooden table in the back of the main meeting area on the first floor.
