Roost makes it easy to rent out the extra space you have in your home. Like kitchen cabinets and crawl spaces. Rent every nook and cranny to anyone. In this week's episode of On The Brink of Greatness, Steve Goldbloom and the team embark on a Cribs-style tour of the growing startup. From the cozy office/living room to the meeting room with an innovative mattress lying on the floor, Roost is going to be huge even if its office is teeny tiny.
