Search/e-commerce firm Accoona, which withdrew its IPO late last year, has now been bought by B2B search engine Masterseek, which was founded in Denmark in 1999. Although the site once generated buzz as a search startup, most of its revenue came from e-commerce, a business running deeply in the red. The company does say it is has achieved some success in China, where Accoona has supplied the search function to both Sina.com and Sohu and has an exclusive partnership with China Daily News. After the integration, Accoona will initially be re-launched in the USA and China, and in Jan will also be launched throughout Europe. More details in release.
