TechTown in Detroit has boosted the number of companies operating in its first incubator, by 50 percent in March. TechOne is to welcome three tenants, the advanced engineering firm Bioko, the IT company IC Datacom and the life sciences venture USA Skills. The moves put TechOne\'s occupancy timetable ahead of schedule. \"This surge of tenants has created a good problem in that we\'re now pressed to find other locations within our building to house our next candidates for space,\" said TechTown executive director Howard Bell.
