The dramatic rise of mobile, opt-in video advertising has helped fuel revenue growth for the New York-based adtech firm Jun Group by 120% in 2013 and the company is on pace for that kind of growth this year as well, says CEO Mitchell Reichgut  in this interview with Beet.TV. In the last few years, Jun Group has expanded its work in video to deliver native ads for publishers across a range of venues, with a focus on mobile.

Jun Group works with brands and publishers that reach 100 million users, he tells us. That includes brands such as McDonald’s, Kellogg’s, Unilever, Microsoft and Chrysler, and publishers including Time Inc., Meredith, Conde Nast and Wenner Media.

The company’s SDK can be used to connect with mobile apps. “As we started to see the rise of tablets and smart phones we thought we needed to do that  and we can reach 100 million people that way in mobile apps, from big editorial publishers down to texting apps or map apps,” he says, adding that all the environments are brand-safe and opt-in. Given the broad marketplace concern over viewability and fraud, the Jun Group platform can effectively guarantee all ads are seen, he explains. “We know where it’s going to run and that’s how we built the system,” he says.

Disclosure: Jun Group is a sponsor of Beet.TV and will be presenting a leadership event, with us on video advertising on July 23 in NYC.
