Only six months ago Barcelona-based TravelPerk bagged a $21M Series B, off the back of strong momentum for a software as a service platform designed to take a Slack-like chunk out of the administrative tedium of arranging and expensing work trips. Today the founders’ smiles are firmly back in place: TravelPerk has announced a $44M Series C to keep stoking growth that’s seen it grow from around 20 customers two years ago to approaching 1,500 now. The business itself was only founded at the start of 2015. Investors in the new round include Sweden’s Kinnevik; Russian billionaire and DST Global founder Yuri Milner, and Tom Stafford, also of DST.
