The story

Hammerhead Networks was founded in April 2000 by Eddie Sullivan, who was chief executive officer. The company focused on software enabling carriers and service providers to deliver differentiated IP services, an area of significant investment in the early 2000s as providers sought to add value to their broadband and data networks.

Cisco had previously held a minority stake in the company. On 1 May 2002, Cisco announced it would acquire both Hammerhead Networks and Navarro Networks in transactions together valued at approximately $258 million, with the Hammerhead portion worth up to $173 million in stock.
