A sort of auction site for ads, PubMatic attempts to match its ad inventory against its subscriber base of small- and medium-sized web publishers to maximize the revenue of the latter.
The company says it has about 1,500 publishers on board and seven of the top eight ad networks. We last wrote about the company in August, before its opened its service for public beta testing.
PubMatic is co-based in India and Menlo Park, Calif. Its $7 million investment was led by Nexus India Capital, with participation from Draper Fisher Jurvetson and Helion Ventures.
