Mobile advertising network Mojiva has raised a further $7m in funding from current investors, with the money part of a wider funding round.

TechCrunch reports that the company is currently closing a round of funding that will be used to hire more staff, build more data layers into its network and expand its new tablet advertising network.

TechCrunch came across the $7m figure in a Form D filed with the SEC, although it has since confirmed details with Mojiva CEO David Gwozdz, who said, “This Form D is the tip of the iceberg, the first bit to a larger amount to be drawn as we need the funds along the way.”
