Tech firms raise new funds

New York-based venture firm FirstMark Capital and London-based Atomico have each raised new funds, capitalising on their success in early-stage technology investing. FirstMark Capital raised $225m (£141.4m) new venture fund, its third, less than a year after raising another fund of the same size, it said in a release yesterday. Atomico, the London-based venture firm created by Skype co-founder Niklas Zennstrom, raised $476.6m for its third fund, according to a filing on Friday with the Securities & Exchange Commission. Atomico’s last fund of $165m was announced in March 2010.
