Jun Group is a video advertising platform on the move after raising $2.5 million in debt funding last month – and one direction it’s moving is mobile.

The New York-based outfit helps brands place video ads and sponsored content on Jun’s network of premium web publishers like Business Insider and CNN.

“Seventy percent of the work that we do is now on mobile – that’s up from 30% in 2012,” says CEO Mitchell Reichgut, whose firm introduced a software development kit in 2012 that supports mobile apps.

“Brands understand the ads are moving there. Mobile applications are where the audiences are living.”
