Finovate confirmed by email this morning that data science specialist Feedzai raised $17.5 million in new funding in a round led by Oak HC/FT. The capital takes Feedzai’s total to more than $22 million, and will help the company grow its engineering and sales talent to help meet demand for the company’s anti-fraud technology.

Participating along with Oak HC/FT in the Series B financing round were existing investors Espirito Santo Ventures and Sapphire Ventures (formerly SAP Ventures). Oak HC/FT will send two of its own, General Partner Patricia Kemp and Venture Partner Jonathan Weiner, to serve on Feedzai’s board of directors.

Kemp highlighted Feedzai’s big data science and machine learning background as key to her firm’s decision to invest. Feedzai’s technology analyzed more than 18 billion transactions in 2014, equaling more than $760 billion in payment volume. The company’s Fraud Prevention API for developers handled transaction growth of more than 300% “in late 2014.”
