About a year ago, we first wrote about CivicScience, an online polling startup based in Pittsburgh that had just raised $1.2 million in seed funding from research firm The NPD Group, national polling company ALR, and The McClatchy Company director Kevin McClatchy, among others. Since then, the company has been busy expanding the number of publishing partners who use its polling widgets, which in turn has dramatically increased the number of users taking its polls, which makes its data all the more valuable. Now it has raised an additional $2.86 million from Boston-based New Atlantic Ventures, as well as big media publisher Cox Enterprises. Along with the investment, New Atlantic founder and managing partner Todd Hixon will be joining the startup's board. And Cox has begun deploying CivicScience polls across its digital properties.
