Wisconsin startup accelerator gener8tor announced the four companies that were born from its inaugural Accelerator Studio, a program designed to build startups from scratch using only Wisconsin-based entrepreneurs. The companies, which were created during the four-month program that began in August, were unveiled Monday. The Accelerator Studio works by partnering with entrepreneurs who come in with no concept for a business, and they work with gener8tor’s team over the course of the program to come up with a unique product or service.
