In addition to the traditional consulting offered, Harris has developed software data platforms that allow brands to track health and campaign success.

The firm works with clients in three primary areas: brand strategy and tracking,[1] corporate reputation,[2] and research for public release.

It was acquired from Nielsen in 2017 by the Stagwell Group, which hired co-chief executive officers John Gerzema and Will Johnson, who relaunched the firm as The Harris Poll.

The Harris Poll runs the longest-standing and largest data set on public opinion research on the coronavirus pandemic in the United States through its COVID-19 Tracker, a biweekly online survey of a nationally representative sample of American adults.

[20] After graduating from Harvard College in 1976, Penn and his future business partner Doug Schoen started Penn & Schoen[21] – now PSB Insights - and helped elect more than 25 government leaders in Asia, South America and Europe, including Tony Blair[21] and Menachem Begin.

[22] Penn was also CEO of Burson Cohn & Wolfe, a public relation company owned by WPP Group, from 2006 to 2012.

[36] Will Johnson was named co-CEO of The Harris Poll in 2017,[26][27] after a decade as an executive in advertising, marketing and consumer research.

Immediately prior to joining The Harris Poll, he was president of BAV Consulting, a Young & Rubicam company, today known as VMLY&R, and chief strategist of BrandAsset Valuator, an analytic survey of brands and consumer behavior.
