Aggregate Knowledge, a provider of real-time personalization and audience-centric display optimization solutions, has raised $9 million in Series C financing.  OVP Venture Partners led the round.  Kleiner Perkins Caufield and Byers, DAG Ventures, and its original existing angels all participated in the round as well.  

Lucinda Stewart, managing director of OVP Venture Partners on reasons for the financing said, "Aggregate Knowledge fits in perfectly with OVP’s advertising analytics investment thesis, namely, that the big exits in the next 3-5 years will be from companies with the infrastructure to harness the power of ‘big data’ to derive actionable customer insights."

The funding for Aggregate Knowledge comes on the same week funding for another online analytics company, Quantcast, received $27.5 million led by Cisco.  

San Mateo, Ca.-based Aggregate Knowledge said it is currently expanding its core distributed machine-learning infrastructure to help agencies and advertisers manage, personalize, and monetize their audiences.  The company previously focused on helping e-commerce vendors power product recommendations, but as explained in the press release, is looking to touch the entire display ad industry.

With now a total of $34.2 million in funding over the past three years, the startup plans to build upon its platform and business, and hire some new staff.
