Defenders, which was founded by husband and wife Dave and Jessica Lindsey in 1998, has grown at a 20 percent annual rate the past two years, with revenue projected to exceed $600 million this year. And with security systems in only 22 percent of U. S. households and home automation technology taking off, Defenders CEO Jim Boyce is confident there is still plenty of room for growth. “This is a great, great business,” Boyce told IBJ. “There are tons of innovations going on within this industry and that’s going to push growth. ”But the potential has spawned a plethora of new competitors, from cable television providers such as Comcast, to telephone companies including ATandT and Verizon, and the latest—internet retail behemoth Amazon. The leaders at Defenders aren’t overly concerned. “We are excited to see new entrants in the home security industry,” Boyce said. “We believe these brands will increase consumer interest for security and smart home solutions and help grow the overall category. ”All of Defenders’ revenue comes from residential security systems installed nationwide, a total the company predicts will hit 2 million next month.
