MediaMath announced a $73.5 million Series C financing round, led by Boston-based growth equity firm Spring Lake Equity Partners, formerly the private equity arm of Tudor Investment. In addition to the Series C financing, MediaMath increased its debt facility to $105 million, for a total funding of more than $175 million.

The Series C financing also included participation from new investor, Akamai Technologies, and existing investors Safeguard Scientifics, Catalyst Investors and Observatory Capital. The company debt facility was led and syndicated through Silicon Valley Bank.

“We are very pleased to have Spring Lake Equity Partners join the MediaMath family,” commented Joe Zawadzki, CEO of MediaMath. “Not only does their investment in the company represent a tremendous validation of our leadership position in the industry, but their strategic insights, deep relationships, and significant resources will play an important role in this next phase of the company’s, and the industry’s, evolution, helping us continue our global expansion and technological innovation.”

The funding will be used to continue MediaMath’s rapid global growth and support its new international offices in the EMEA, APAC, and Latin American markets. Furthermore, the proceeds will help develop and accelerate the introduction of new products and features of its flagship technology, the TerminalOne Marketing Operating System, which enables modern marketers to reengineer their marketing for transformative results.
