Transportation marketplace uShip.com has closed an $18 million round of Series C financing with Kleiner Perkins Caufield & Byers to extend the development, sales and marketing of uShip’s commercial freight platform, mobile platform and global presence.

The company also announced that Maritza Liaw, partner at KPCB, will join uShip’s board of directors.

The funding will enable uShip to develop its new “PRO” platform, currently in private beta, which allows business shippers and freight brokers to build their own carrier networks and manage and automate shipping operations. It is aimed at the truckload freight market in the U.S.
