Carmel Ventures, Index Ventures, Gemini Israel Ventures, GlenRock Israel, Rhodium, Lightspeed Venture Partners and Vintage Partners also participated in the round.
Outbrain, which currently has 13 offices around the globe, will use the funds for further expansion. It currently serves more than 130bn organic and paid content recommendations per month and its links appear on websites such as CNN, Slate, ESPN, The Telegraph, Le Monde and The Guardian.
HarbourVest Partners principal Ian Lane said, “We’ve been following Outbrain’s progress for over two years and continue to be incredibly impressed with what Yaron and the rest of the team have created.
“This is a company committed to providing value to readers and publishers through quality content. Outbrain is a clear leader in a growing and increasingly important part of the internet advertising marketplace. HarbourVest is excited to partner with management and current investors in the next phase of Outbrain’s growth.”
The round follows Outbrain’s $35m Series D, which was led by London-based growth investor Index Ventures in December 2011.
