SAN FRANCISCO, Jan. 23, 2014 /PRNewswire/ -- AdRoll, the most widely adopted retargeting platform, today announced the acquisition of userfox, a Y Combinator-backed startup offering user-retention-as-a-service for brands of all sizes.

Founded in 2012 by Peter Clark and Cesar Alaniz, San Francisco-based userfox's email retention service sends over two million emails per month for thousands of customers. The company was created to tackle challenges faced by the company's founders while operating Vimessa, a video voicemail application that allows customers to send high-definition video messages to mobile numbers and email addresses. The founders pivoted their business into userfox in November 2012 and launched retention-driven email, newsletter management and A/B testing products in 2013.

Complementary to AdRoll's goal to help marketers "collect, analyze and act" on their data, the userfox integration will enable advertisers on AdRoll's platform to gather and execute on valuable customer data from a variety of sources, including CRMs, email lists and mobile IDs. As a result of this acquisition, Peter Clark will lead AdRoll's product efforts to integrate new data sources and partner with email providers.

"Like AdRoll, we created userfox to bring marketing technology typically reserved for Fortune 100 businesses to companies of all sizes and we have always been relentless about raising the bar for simple yet effective products," said Peter Clark, userfox CEO and co-founder. "I'm excited for the opportunity to focus on helping AdRoll build and deliver delightful, innovative products to tens of thousands of customers around the world."

"Userfox stood out to us because they share AdRoll's vision of making complex marketing technology perform for a broad market," said Aaron Bell, AdRoll CEO. "AdRoll is dedicated to creating products that drive ROI for marketers and userfox will be a critical addition as we continue to grow this year."
