The North Dallas father runs Backyard Movie Theater, a Texas business that sets up inflatable cinema screens, sound systems, and themed seating for parties, schools, and neighbourhood events. He never set out to build a company. 'It was a Christmas gift for my family,' Derek told entrepreneur Chris Koerner on his YouTube show, The Koerner Office.
