Epic, the healthcare-software giant, is a famously secretive company that mostly doesn’t market its wares and yet remains the dominant force in its sector.

Only about 1 percent of Epic’s employees  are  in sales and marketing. The company doesn’t issue press releases and he hasn’t a “media” department on its Web  site.

“When I started the company, I had no idea how to do marketing, so we just didn’t do it,” founder, in 1979, and still CEO Judith Faulkner told Becker’s Hospital Review. “What I did know, because I was a technical person, is to be able to write good software. So we focused on writing good software, and we focused on doing good support. And then fortunately, word of mouth did the rest.”
