Former Quorum CEO Larry Lang is in as the new CEO at OpenStack virtual networking startup PLUMgrid. The appointment, announced Tuesday morning and effective immediately, will see PLUMgrid founder and outgoing CEO Awais Nemat appointed chairman of the company's board.

In Lang, PLUMgrid gets a seasoned networking veteran with over a decade of executive experience at Cisco. In 2010, Lang was called in as executive middle relief pitcher at Quorum, building out the disaster recovery startup's sales team and pipeline and leading the firm through its Series B and C rounds.

Now PLUMgrid hopes to get a similar business-side boost by bringing in Lang. “Our strategy to launch the next phase of growth is centered on bringing aboard a CEO who could leverage our innovative technologies and reference customer wins into broad market adoption," outgoing CEO Nemat said in a statement.

Founded in 2011 and backed by total funding of $29 million, PLUMgrid has shifted its product focus heavily toward OpenStack environments in the past year. The company's virtual networking software suite plugs into OpenStack to let users create private virtual domains for isolation and policy enforcement in multi-tenant environments.

PLUMgrid counts financial services cloud provider Swisscom among its customers, and claims 70 deployments worldwide.
