On the heels of debuting a tablet-only ad network, mobile advertising company Mojiva Inc. has raised $7 million in fresh funding.

The financing round was revealed in a regulatory filing yesterday and follows a $25 million Series C round secured in July 2011.

The company’s two main solutions are mobile media network Mojiva and mobile ad serving platform Mocean Mobile.

Its new, aforementioned tablet-only ad network (dubbed Mojiva Tab), will self-reportedly reach more than 40 million tablet computers worldwide.

Its network is said to cover more than 1.1 billion devices globally.

Mojiva is backed by Bertelsmann Digital Media Investments, Shamrock Capital Advisors and Pelion Venture Partners, and is headed by Dave Gwozdz, a former member of DoubleClick’s founding team.

Mojiva is headquartered in New York with offices in San Francisco, Los Angeles, Seattle, Detroit, Chicago and London, UK.

More details about the new financing round couldn’t be surfaced from the SEC filing, other than that it’s definitely a new equity funding round and that it isn’t related to any M&A activity.
