Tech Blog Ad Network NetShelter Raises $15 Million

Longtime blog ad network NetShelter has raised $15 million in its latest round of funding. The company counts more than 200 independent technology news sites, including, MacRumors, and Slashgear, among the sites it sells ads for. CEO Peyman Nilforoush tells us that revenue was up 75 percent last year, although he wouldn’t provide any sales figures.

Nilforoush says that growth came from adding a number of sites to the network and also from increasing ad sales on existing sites. He says that ad sales have continuously outperformed the ad market as a whole because of the super-targeted audiences the technology sites in the network reach. Together, sites in the NetShelter network reached more than 133 million unique monthly visitors in August, according to comScore (NSDQ: SCOR), putting it ahead of rivals, such as CNET and IDG.

NetShelter says it will use the new funding, which was led by Rho Ventures, in part to expand internationally. It brings NetShelter’s total backing to more than $26 million. The company last raised cash two years ago, when it got $11 million in a first round.
