Need a little breathing room? Now you can get one—literally. Breather, a start-up based in Montreal, offers over-stimulated urban dwellers the opportunity to rent serene work and hangout spaces by the hour. (Don't get any R-rated ideas: hanky panky and illicit activities are strictly forbidden). With so many companies adopting open-floor plans, leaving employees in perpetual search of a place to hide, this idea may have legs. In fact, it's already raised more than $6 million in capital, and is operating in four cities. Would you pay around $30 per hour for a room of your own? Do you think this business will succeed?
