LinkedIn knocked its Q3 earnings release out of the park on Thursday. The company also announced a strategic partnership with EY (formerly Ernst & Young).

LinkedIn CEO Jeff Weiner called it the “largest single deal in our history”.

The deal is designed to “accelerate business-to-business growth by bringing cutting-edge social selling technology and data analytics to market around the globe,” an EY spokesperson said.

“Together, EY and LinkedIn will help more companies around the world leverage technology, social networks and innovative sales techniques to get their products and services to market more quickly and effectively,” they said. “The exclusive pact will also help companies develop deeper and more trusted customer relationships through social and data analytics. As part of the alliance, EY will also integrate LinkedIn’s Sales Navigator tool into its business development efforts by encouraging its people to develop relationships, build credibility and interact through social channels.”

Mark Weinberger, EY’s Global Chairman and CEO said, “This will be a powerful relationship. EY and LinkedIn are both driven by a sense of purpose. At EY, we continually strive to build a better working world by bringing our clients the tools and services they need in a rapidly changing business environment. Data analytics and technology have transformed the way companies operate, and together, EY and LinkedIn will provide organizations with leading-edge tools to navigate those changes.”

LinkedIn announced on Thursday that it has reached 400 members.
