Atomico, the European venture capital firm founded by Skype’s Niklas Zennström, is announcing a number of new hires to its investment team, including new Partner Caroline Chayot, who previously led the EMEA HR team at Twitter. I’m told she’ll be working alongside existing Atomico Partner Dan Hynes, who was formerly the Director of Global Staffing at Skype, with the pair helping meet increased demand from Atomico’s portfolio companies for talent support. At Twitter, Chayot is said to have supported the leadership team in scaling the social media behemoth from two to six markets, growing the team from 80 based in London to 500 across the region.
