Chief Operating Officer

Efrain is responsible for Global Online Operations for Lightspeed Research.

In a career that spans over 25 years, Ribeiro has been an innovator in the online panel business and set standards for quality and best practices. He began his career at The Arbitron Company where he was responsible for both the radio and television service operations in the ‘80s and early ‘90s.

As Head of Global Access Panels at TNS/NFO in 1999, Ribeiro developed and launched one of the first online custom panel services. He was responsible for the recruitment, management, sampling, and research-on-research for consumer, web-based, and proprietary global panels. Efrain’s efforts resulted in high response rates, long panelist tenure, and the development and adherence to best practices with particular emphasis on meeting clients’ sampling and timing requirements.

Prior to joining Lightspeed Research, he was COO and Head of Respondent Access and Engagement at Ipsos, where he oversaw the operations and development of their online and offline panels. He is an original member of the ARF Online Research Quality Council Steering Committee and was instrumental in conducting the 2009 groundbreaking study Foundations of Quality.
