A little over a year since it last raised an undisclosed round of funding, Ad network PubMatic has raised $7.5 million from existing investors Helion Venture Partners, Draper Fisher Jurvetson and Nexus Venture Partners. All in all, that takes the total amount of funding that Pubmatic has raised since launch to $18 million. Pubmatic CEO Rajeev Goel claims that their revenue has grown 700 percent year-on-year, but without actual revenues being disclosed, or the base amount on which this growth is calculated, it means little.

This round of funding, according to the release, will be used to accelerate the adoption of their new offerings, which includes an impression-level ad auction with real-time bidding (white paper) and audience analytics. Last month, it tied up with ContextWeb to allow publishers to sell inventory on the ASDAQ Ad exchange, with real-time bidding. Pubmatic’s sister concern, Komli Media operates in India, and also owns the audience measurement business Vizisense.

PubMatic is a sell-side ad network and focuses on maximizing revenue, control and protection from malware for premium publishers, as opposed to demand-side networks that focus on optimizing audience deliverables to agencies. It allows premium publishers like IAC, The Huffington Post, eBay, among others, to make their advertising inventory available for sale to advertisers, and claims to have a majority of the Comscore Top 10 on board. Helion’s Ashish Gupta is betting on the company becoming the most advanced sell-side platform for publishers.
