They’ll face six other regional finalists all pitching-off on May 26 for the $25,000 grand prize from Maine Technology Institute. “I would like to point out LA had the Top Gun winner for the state last year, so we’re pretty excited about the entrepreneurial supports and pathways in the region,” Shanna Cox, president of the Lewiston Auburn Metropolitan Chamber of Commerce, said Thursday as the fifth annual Top Gun LA pitch-off got underway.
