The firm did not disclose how much was invested. The cash will be used to expand its daily collection and analysis of public opinion data.

Rasmussen does not carry out polls on behalf of clients. Instead, it makes its money from selling advertising, title sponsorships, subscriptions and content, with survey topics dictated by subjects in the news.

Scott Rasmussen (pictured), the firm’s founder and president, said: “This investment will enable Rasmussen Reports to expand and enhance all aspects of our business. That includes expanding our Premium Membership service and subscription base, developing new index products and sponsorship opportunities and exploring new research techniques.”

Ted Carroll of Noson Lawen Partners said: “We admire the rock-solid credibility and market-leading accuracy of the Rasmussen Reports product suite, and we are going to be actively engaged with Scott and his team as they expand it.”
