33Across, a New York City-based startup at the intersection of two of the biggest trends in tech — Big Data and social marketing — just closed a round of financing led by Pelion Venture Partners. The transaction is valued at $13.1 million.33Across lays claim to the world’s “largest social and interest graph,” besting both Google and Facebook. The company’s technology platform leverages Big Data and predictive analytics to turn unstructured data, including social and search signals, into intelligence that marketers and publishers can use to better engage consumers and online audiences.”Big Data has the potential to transform digital marketing and publishing, and this capital infusion accelerates our position as the most trusted partner for the world’s largest advertisers and content owners,” said Eric Wheeler, CEO of 33Across. It’s a boastful claim, but not one without some merit.
