Bertelsmann, a media company based in Germany, said last week it is buying Relias Learning from its current owners, Vista Equity Partners and LLR Partners.

Relias headquarters will remain in Cary, NC, and company representatives said they expect to continue to add to their 300-employee base.

“Relias has grown tremendously over the past few years due to our dedication to our customers and our passion for delivering the world’s best online training,” said Relias CEO Jim Triandiflou. “Bertelsmann’s entrepreneurial culture, commitment to world class products, international reach, and financial backing will allow Relias to continue investing in our core U.S. markets, as well as internationally, ensuring that we have the very best products in the world.”

Relias Learning was formed in 2012 via an investment by Vista Equity Partners and the merger of Essential Learning and Silverchair Learning Systems. The company’s client base includes more than 4,000 organizations with more than 20 million courses completed annually. Credit Suisse is the company’s exclusive financial advisor.
