LEWISTON — The Lewiston Auburn Metropolitan Chamber of Commerce will host a Top Gun Regional Pitch Off at 5 p.m. Wednesday, May 9, at the Ramada Conference Center, 490 Pleasant St.

Four teams of entrepreneurs will present five-minute pitches on their businesses to a panel comprised of local public and private sector leaders. Participants will engage in promoting their business in front of a relevant audience.

Two winners will be selected from the Top Gun LA group to advance to the statewide Top Gun Showcase in Portland on May 23, where they will compete for a $25,000 grand prize.

Top Gun LA is designed to accelerate entrepreneurial development through a combination of training, mentoring and community engagement. Top Gun identifies high potential entrepreneurs in Maine through a competitive application process in January. In February, they are matched with mentors who help guide them as they continue to develop their innovative products, business models and companies.

The classes of six to 12 entrepreneurs in each location convene weekly for networking, workshopping and mentor meetings. Sessions can include opportunities for pitch practice, brief presentations by experienced entrepreneurs, and lively discussions about such diverse topics as salesmanship, bootstrapping, hiring, firing and legal issues.

The event is free. To register go to lametrochamber.com.
