New investor Edison Ventures led the funding round, and it was joined by new investors Hearst Ventures and Salesforce.com, as well as existing investors Windcrest Partners, CommonAngels, and Mesco.
Offerpop said the cash will go toward accelerating innovation of its platform, as well as fueling expansion of its current operations in the U.S. and Europe, and new offices elsewhere.
CEO Wendell Lansford said in a release announcing the funding round:
The world of brand marketing is changing every day. With the rise of mobile and social, the most powerful content is now user-generated. And the most effective marketing is authentic and consumer-driven. Offerpop provides a complete solution for this new reality, allowing brands to adapt to a new marketing landscape driven by social and mobile consumers and content creators.
