In 1987 Nanos founded SES Research while he was a student at Queen's University. The company is now known as Nanos Research, a market and public opinion research firm with clients across North America.
In the 2006 federal election, Nanos predicted the results to within one tenth of one percentage point for the four major parties - a record in Canadian polling history.
Nanos Research was the official pollster for CPAC, Canada's Political Channel until 2009. The Company remains the pollster for the Osprey Media Group (a chain of 51 newspapers in Ontario) and the Rogers Radio Network.
Nanos was the 2006-2007 National President of the Marketing Research and Intelligence Association (MRIA), which governs and accredits over 260 research organizations and over 1,700 research professionals.
During his tenure, he presided over the launch of the Charter of Respondent Rights, the renewal of the marketing research industry’s professional designation and a review of the standards regulating market and public opinion research in Canada.
He is a past publisher of the Canadian Journal of Marketing Research and past Editor-in-Chief of Vue, the official magazine for the market research industry in Canada.
Nanos has been awarded patents in the U.S., Canada, Germany, the U.K., Ireland, France and Austria for an automated, real-time research process called “ask” (automated survey kiosk) which is deployed to allow clients to have real-time access to customer input during the retail experience. A patent is also pending on this interactive, multi-lingual wireless research technology with the world intellectual property organization.
In 2008, Nanos was appointed an associate professor in the Canadian studies program at the State University of New York at Buffalo.
In May 2010, Nanos was elected Fellow of the MRIA (FMRIA).
