Zipit Wireless Selects Rainmaker's GrowCommerce Store-front Enhanced with Global Commerce Services Campbell, Calif., April 17, 2013 - Rainmaker Systems, Inc. (NASDAQ: RMKR), a leading global cloud e-commerce company, announced today that Zipit Wireless has selected Rainmaker's GrowCommerce platform to deploy its Zipit e-commerce storefront with Rainmaker's Global Commerce Services to manage customer acquisition online and over the phone.

Zipit Wireless has selected Rainmaker Systems to implement a B2B e-commerce store-front targeting its mid-market. The Zipit Store will offer the complete Zipit Wireless Critical Paging and Secure Texting solution, including the Zipit Now™ device and the Zipit Confirm™ Smartphone Application for iOS & Android. The ability of the Zipit Now™ device to dynamically switch between internal wireless (Wi-Fi) to the Verizon Wireless 3G nationwide cellular data network,
at price points typical of inexpensive and unreliable pagers, enables professionals to communicate with unparalleled security, tracking and accountability regardless of their location. These same great features are also available as a cross-carrier Smartphone application. Zipit Wireless will utilize Rainmaker Global Commerce Services agents to guide visitors through the sales cycle via instant chat, over the phone and by email.
"We recognize there is an exponential growth opportunity for us by expanding our product and solution offerings to the mid-market through an e-commerce storefront. Rainmaker's solution combines a fully functional e-commerce platform with Global Commerce Services agents, enabling customers to leverage a true buying experience over the Internet, while allowing Zipit
to scale our business and expose our solution to thousands more customers," said Frank Greer, CEO of Zipit Wireless.
"Zipit Wireless recognized that there was a hidden revenue opportunity in their mid market and chose Rainmaker for our proven track record, quick launch time, and short path to an attractive ROI," said Christina Cherry, Rainmaker's Vice President and General Manager of Global Commerce Services.
