A whopping $80 million dollars has been raised by Turn.com in a Series E funding led by two of the ‘world’s largest’ investment firms.

The 2006-founded marketing software and analytics platform helps global marketers plan, implement and analyse cross-channel digital marketing campaigns.

While the California-headquartered firm has not said who the two mystery investors are, it added that new investors also included ClearBridge Investments, Firsthand Technology Value Fund, Northport Investments and Pine River Capital Management.

Current investors Norwest Venture Partners, Trident Capital, Shasta Ventures and Focus Ventures also participated in the round.

President and CEO of Turn, Bill Demas, said the Series E proceeds will accelerate investment in the company’s technology platform, data science and machine-learning algorithms, and cross-channel and data-focused products, as well as its continued global expansion.

“Turn is helping global businesses unlock new opportunities for growth by providing the real-time insights that enable them to find, understand and communicate with their most valuable audiences – at the right moment, on the right device, and at the right time,” Demas said.

Managing partner of Norwest Venture Partners, Jeff Crowe, said the business is encouraged by Turn’s stellar track record and is confident in Turn’s leadership and potential in the ‘post-ad-tech’ landscape.

Turn, which offers Audience Suite, DataMine, and Campaign Suite; for video, mobile, social, and display advertising, has nine offices across the Americas, six in Europe, and four across Asia Pacific.
