The Irvine, Calif.-based WebVisible has raised $17 million in venture funding over the past three years, most recently securing  $12 million in a second round from Redpoint Ventures in March. WebVisible markets software to small businesses with the promise of better management of their online ad buys. The company’s management tools operate across a range of platforms, including search engines, which is where Adapt Technologies comes in.
