Following the acquisition, Pivotal will have a 500-person team working on application development, the company said.

Pivotal is backed by industry heavyweights Vmware and EMC. Xtreme Labs is the company's first acquisition.

Since its founding in 2007, Xtreme Labs has worked for a number of big-name clients, including Facebook, Twitter and MTV. The company has also done work for The Globe and Mail.

"The convergence of mobile, social, big data, and cloud is driving extraordinary change in the enterprise." Xtreme Labs co-founders Amar Varma and Sundeep Madra said in a statement. "To help customers win in this new era, Pivotal is enabling the creation of modern software applications that leverage big and fast data – on a single, cloud independent platform."

Xtreme Labs did not disclose the purchase price to The Globe and Mail. Citing sources close to the deal, All Things Digital reported the price at $65-million (U.S.).
