Only four months after formally launching, mobile startup Quattro Wireless has raised $12.3 million in a second-round of venture financing led by Globespan Capital Partners. Quattro develops mobile Web sites and marketing campaigns and is building a mobile platform linking publishers and advertisers.

Quattro’s GetMobile Exchange will allow customers to buy and sell mobile advertising on a pay-per-click or CPM basis while offering exclusive inventory and campaign reporting capabilities. The company’s clients to date include Gillette, Univision, Playboy and NFL.com.

Started by the founders of mobile developer m-Qube (sold to VeriSign last year for $250 million), Quattro has raised a total of $18 million so far from investors that also include Highland Capital Partners.

The company will use the money to help launch the GetMobile platform later this fall.

GetMobile will compete with other mobile ad platforms including those from Third Screen, Yahoo and startups such as AdMobs.
