German entrepreneur Christian Braun is scrolling through the pages of his collectibles web site, hobbyDB.com, with his team in a downtown Boulder office building. From the ceiling above him hang flags representing countries from all over the world. Whiteboards form a perimeter around his space with yellow and pink Post-It notes on all the walls and windows. The scent of Indian food is thick in the air, from a table filled with large amounts of takeout food.
