Jeff Greenfield Takes A ‘Buy Side’ Role at WideOrbit


He was the co-founder and COO of C3 Metrics, which he launched in May 2008 in Portsmouth, N.H.

Now, Jeff Greenfield, who in June 2020 became a strategic advisor to Overnight Dealer, has joined a media technology company devoted to making it easier to buy and sell advertising.

Greenfield, in an update to his LinkedIn profile, has confirmed that he will now serve as SVP Buyside for WideOrbit.

It’s a big move for Greenfield, an entrepreneur, marketer and technologist who has created some of the most innovative and effective marketing and technology programs over the last two decades.

At C3 Metrics, he served as the chief architect of the Attribution Data Cloud, serving billions of impressions for clients including JP Morgan, US Bank, Hertz, Nestle, Peapod, Carhartt, Edward Jones and Fender.

Further, Greenfield’s extensive work with the Media Ratings Council led to accreditation for viewability and the creation of attribution accreditation, the first for the industry for which he was recognized at the Market Research Council — where he was named a “Star of Attribution” by Sequent Partners.

Greenfield has also been a regular presence at key industry conferences, including those staged by the NAB and NATPE.
