By Sarah McBride SAN FRANCISCO (Reuters) – Atomico Partners, a London-based venture firm founded by Skype co-founder Niklas Zennstrom, is suing a former employee and consultant for secretly diverting potential Atomico investments to a venture firm that the two were building. The employee, Pogos Saiadian, and the consultant, Wouter Gort, reached out to startups and potential investments using their Atomico credentials, according to a lawsuit filed Tuesday in state court in Delaware. But once they got their attention, they ended up investing on behalf of Greyhound Capital, a venture firm they started while working at Atomico. All along, they could draw on Atomicos reputation for backing high-profile ventures like \Angry Birds\ developer Rovio and the Climate Corporation, a weather data company that Monsanto bought last year for $1.1 billion.
