SEATTLE, WA – May 3, 2011 – ExtraHop Networks, a leading provider of network-based application performance management (APM) solutions, today announced it has secured $14 million in series B financing led by Meritech Capital Partners, a leading late-stage venture capital firm. The over-subscribed funding round also included participation from Madrona Venture Group, an original investor in ExtraHop, as well as other private investors. The new funding will be used to further ExtraHop's strong growth trajectory and build on the company's proven ability to help customers spanning a wide range of industry verticals, including travel, transportation, technology, communications, and retail, deliver superior customer experiences and lower IT costs.

Meritech Capital Partners focuses on late-stage venture capital investments in category-defining technology companies, including Salesforce.com, Facebook, Riverbed, and Zipcar, and currently manages $2.6 billion in capital. With the Meritech Capital Partners team of Paul Madera, George Bischof, Mike Gordon, and Rob Ward, along with Madrona Venture Group Managing Director Matt McIlwain, this latest funding round for ExtraHop includes participation from five venture capitalists listed in Forbes' 2011 Midas List of the Top 100 Tech Investors.

"We are very excited to engage with the ExtraHop team as it takes the company to the next level," said George Bischof, Managing Director of Meritech Capital Partners and former investor in Wily/CA. "Having spent time at companies in the application performance monitoring industry, I can say with a lot of confidence that ExtraHop's solution is truly innovative. As a real-time, network-based, passive solution, it brings APM capabilities to market that weren't previously available in other offerings. This late-stage investment with ExtraHop underscores Meritech's mission to invest in highly successful technology companies that grow to define their markets."

ExtraHop's position as a market leader has been achieved by building the award-winning ExtraHop Application Delivery Assurance system to ensure that business-critical transactions do not fail. By providing an unprecedented level of real-time monitoring, visibility, and analysis, the solution accelerates network and application troubleshooting efforts and proactively warns of potential problems before they turn into large disasters.

"With such an outstanding group of investors backing us, we're looking forward to taking our company to the next level. Our goal with this latest injection of capital is to continue doing what we do best—delivering innovative solutions that solve business-critical problems for our customers, and in doing so, naturally solidifying our position as the leader in network-based APM."
