Online bulletin-board service Pinterest on Wednesday announced the acquisition of Spanish startup Icebergs, specializing in helping creative people collaborate on projects. The acquisition was aimed at beefing up Pinterests team, particularly with Icebergs co-founders Cesar Isern and Albert Pereta. For years, Cesar and Albert have been building technology to improve online visual curation and organization of projects, and were excited for them to join us, Pinterest said in an email to AFP. Icebergs services will be discontinued on the first of September, and the startups founders will come here to work for Pinterest.
