Corey Weiner is taking over as CEO of mobile ad company Jun Group

After 18 years at the helm, Mitchell Reichgut is stepping down as CEO of Jun Group, with COO and president Corey Weiner taking over as chief executive.

The news comes just about a year after Jun Group was acquired by Advantage Solutions, but Reichgut said the acquisition was a "non-factor" in his decision.

"I think it is the right time for the company to have a leadership change," he said. "I have been stepping back more and more, so it's a natural progression, with a bunch of managers here taking on larger roles as I move on."

In addition to Weiner (who's been at Jun Group since 2003), other Jun Group executives taking on new roles include Mishel Alon becoming COO, Leslie Bargmann becoming vice president of client services and Jeremy Ellison becoming vice president of technology.

Reichgut, meanwhile, said he's "stepping back entirely to focus on artwork and writing and community service after a long, long career."

Looking ahead, Weiner plans to double down on Jun Group's approach to advertising, where it builds custom audience segments by polling users in its network, then shows video ads and branded content to interested viewers.

"Our primary motivation is to evangelize that format," he said. "As you know, most advertising is interruptive and consumers don't like that kind of advertising very much - in some cases, they're annoyed by it. This value exchange flips the advertising paradigm on its head. By choosing to engage with advertising, they are getting something amazing in return."
