AdReady Raises $5.3M From Madrona, Bain And Khosla, Strengthens Board

Seattle-based online advertising startup AdReady has raised $5.3 million in funding.

Xconomy had the scoop last week based on an SEC filing, but now we also know the names of the investors, all of which have invested in the company in the past.

AdReady raised its third round from all of its prior backers: Madrona Venture Group, Bain Capital and Khosla Ventures. The Series C round brings the total of financing raised to $17.3 million.

AdReady has also announced the addition of software industry vet Steve Singh, Chairman and CEO of Concur, to its Board of Directors. He will be joining Hulu CEO Jason Kilar, among others, on the company’s board.

AdReady develops software tools that make display ads more efficient to produce and monitor, particularly for small and medium-sized businesses. The company aims to provide centralized, single-point control across all major publishers for end-to-end display advertising management. More info about its products here.

The startup was co-founded by Aaron Finn in 2006. Its President and CEO is Karl Siebrecht, previously general manager in charge of ad platform product management, search and display marketing, and mobile and gaming advertising for Microsoft and prior to that President of Atlas at aQuantive (before its $6 billion acquisition by the Redmond software giant).
