uSamp, an Encino online market research company, on Tuesday said that it has raised $10 million in a “series C” funding round.

The company, founded by Matt Dusig and Gregg Lavin, said the effort was led by OpenView Venture Partners, a Boston firm. The money will be used for operations, acquisitions, development of the company’s next-generation panel management platform and social media technology enhancements.

uSamp, formerly known as United Sample, developed an online platform used to manage online polling and sampling. It said it has more than 2 million active, registered panelists around the world registered with the site to perform surveys for clients. The company earlier this month opened an office in Connecticut and launched operations in India. It now has more than 90 employees.

“Our proprietary panel management platform is key to uSamp’s success, but our global perspective is likewise contributing to our rapid growth,” President Gregg Lavin said in a statement. “The new funding from OpenView Venture Partners will enable us to further extend our global reach, with investment in tools for social media and publishers.”

uSamp’s previous round of funding was in January 2009 and totaled $3 million. The latest round brings total money raised since the company’s March 2008 launch to $14.3 million.
