Two weeks after announcing that participants in two Knoxville area start-up accelerators would attend classes together (see teknovation.biz article here), the inaugural session of that first-ever collaboration kicked off on August 21. The seven participants in Cohort 7 of the “Innovation Crossroads” (IC) program operated by Oak Ridge National Laboratory joined the six start-ups in the second cohort of the “Spark Cleantech Accelerator” for the latter’s 12-week program. They will be working from space at the Spark Innovation Center at the University of Tennessee (UT) Research Park.
