AudienceScience, the behavioral targeting firm formerly known as Revenue Science, has raised $20 million in funding from previous backers Mohr, Davidow Ventures, Mayfield Fund, Meritech Capital Partners and Integral Capital Partners. The company will use the money for new hires, tech R&D and a continued international expansion. It’s a big vote of confidence from the Valley—particularly amid the FTC’s increased scrutiny and pending regulation of the online ad-targeting industry. AudienceScience has raised well over $50 million in funding in total. Release.
