A workplace focused on the “new economy” opened its doors earlier this month in downtown Coeur d’Alene, and it’s already filled to capacity. The Innovation Den, 418 E. Lakeside Ave., is in the 110-year-old Elks Club. Most of the companies in the building are focused on technology, robotics and artificial intelligence. The University of Idaho’s computer science and robotics department is in the building’s basement. An unmanned aerial vehicle company, xCraft, also leases space.
