Hillary Ball, Atomico's growth-focused partner, said the firm was drawn to investing in TravelPerk as it's addressing "a complex and hard problem to solve" around corporate travel.
"This is a market that resurged following the pandemic," Ball told CNBC. "In the past year, the global value of corporate travel was $1.5 trillion — that's up by 6% relative to pre-pandemic and 2019. It's really clear that this is a market that's here to stay and one that's growing."
