forterra-112.pngIn-Q-Tel invests in Forterra Systems, a private virtual world creator – San Mateo-based Forterra’s software platform lets developers quickly create private, online virtual-world scenarios for organizations that can be used to simulate potential real world events, such as a government’s secret spy missions.

After running a scenario, the software lets its users get integrated reports that analyze participants’ actions to figure out what when right and what went wrong.

Besides government agencies, Forterra serves organizations in healthcare, education and other industries.

The amount of funding was undisclosed. The company said a “technology advancement agreement” was part of the deal, which sounds like customization for the needs of the US government. In-Q-Tel invests in technology companies that in some way further the interests of the US intelligence community.

Appfuel, another Facebook ad network, but with better ad targeting – RockYou, VideoEgg, Social Media and other Facebook ad networks have already been active for months. Today, San Francisco-based Appfuel is launching with the claim that it can more quickly and accurately serve targeted advertising within Facebook applications

In one example, if you state you’re a fan of the band the FooFighters on your Facebook profile page, then you might see an ad that shows you information about the band’s latest shows or where you can buy band t-shirts. GigaOm has more.

The company has raised an undisclosed amount of angel funding.
