Prior to his highly publicized stint as CEO of J.C. Penney, Johnson led Apple's retail division, and spearheaded its retail store strategy and Genius Bar, widely regarded as the most successful retail operation in the world. However, Apple is not, at least not yet, an Enjoy partner. (Though Johnson said "stay tuned.")

Consumers can book a visit from an Enjoy expert for $99, with the average visit lasting an hour.  The employment model is unique as well. The experts are salaried employees with benefits, who set their own hours and have equity in the company. Enjoy said there are about 60 experts currently on the payroll.  Enjoy has raised more than $30 million to date from well-known investors such as Marc Andreessen at Andreessen Horowitz, Brook Byers of Kleiner Perkins Caufield & Byers, and Fred Harman at Oak Investment Partners.  Over his long career in retail and technology including his jobs at Mervyn's, Target, Apple and J.C. Penney, Johnson has made both allies and foes, and he's been successfully right and woefully wrong. Many say he is bold, unafraid of taking risks and passionate about ideas he believes are transformative.  While many describe Johnson as a pioneer, others have less-flattering characterizations stemming largely from his dramatic, and failed, strategy at J.C. Penney that cost the retailer half of its market share. Johnson continued to shy away from discussing his tenure at the department store with CNBC.  "Penney's was a very challenging time for me personally, for the company, but I haven't talked about it in two years. The only place I have talked about it has been from an educational perspective at Stanford Business School or Harvard Business School and you can go on YouTube and read about it. But it's a long story and I'm not going to talk about it today," said Johnson, adding that there were "a ton" of lessons learned on both sides.  (UPDATED: This story has been updated to includes details of an interview with Enjoy founder Ron Johnson.)
After being out of the spotlight for more than two years, Ron Johnson is back, working on what he describes is a whole new platform for commerce.
