AppNexus announced that it has raised $8 million in Series B funding and added Mike Tyrrell, general partner at Venrock, to its board of directors. The round was led by Venrock and included Kodiak Venture Partners. AppNexus enables businesses to build robust, cost-efficient and instantly scalable enterprise production infrastructure. The company will use the funding to support product development as well as sales and marketing efforts.

Building and managing infrastructure has historically been an expensive, difficult process that can take months to complete. Brian O'Kelley and Mike Nolet AppNexus, former Right Media executives, launched AppNexus in 2007 to make it easy for businesses of any size to set up secure, redundant and efficient production-ready datacenters. In just one hour, users can reserve top quality servers, launch virtual operating systems, run applications, load balance those applications and store secure data using a self-service interface. Best of all, AppNexus can easily and affordably scale to meet its customer’s changing datacenter needs.

“Our goal is to make it easy and affordable for companies to build and manage their infrastructure so that they can focus on their core business processes,” said Brian O'Kelley, co-founder and CEO, AppNexus. “The response has been overwhelming, and today many of our customers generate billions of transactions per month.”
