Rowan Trollope, Cisco senior vice president and general manager of its Application Division, will step down from his role to become the CEO of cloud software startup Five9, effective immediately. In his role at Cisco, Trollope oversaw both the Internet of Things (IoT) and Collaboration Technology groups at the company.

Five9 was founded in 2001 and builds contact center cloud software for enterprises. The company’s former CEO Mike Burkland transitioned to executive chairman in December for health reasons. In his absence, Five9 CFO Barry Zwarenstein served as the interim CEO but will now resume his role as CFO.

Trollope joined Cisco in 2012 and was largely responsible for the Collaboration group’s shift to a software-as-service model and the group’s first application, Spark, which was recently folded into a single platform with Webex.

In 2015, Trollope was appointed to also lead Cisco’s IoT development and applications. Here, he was involved in the purchase of IoT startup Jasper and the building of its connectivity and data delivery platform, Kinetic.

During his tenure at Cisco, Trollope was a member of the Board of Directors and played a role in the company’s acquisitions of Broadsoft and AppDynamics, both of which he oversaw under the Applications group.

The news comes as Cisco announced its intent to require startup Accompany and its artificial intelligence (AI)-driven relationship and prospect finding platform for $270 million in cash and assumed equity awards. The CEO and founder of Accompany Amy Chang will assume Trollope’s responsibilities as SVP of the Collaboration group. And the Accompany team will join the Collaboration group under Chang.

Accompany’s AI technology will be integrated across the group’s portfolio, including Webex where it will serve as a way to provide user and company profile data.
