ABOUT TRIPACTIONS

TripActions is the fastest-growing corporate travel platform disrupting a $1.5T industry and shaping the future of business travel.

TripActions is a story of inspiration born of frustration. Road warriors and co-founders Ariel Cohen and Ilan Twig believed that companies deserved a travel solution that takes the pain out of work trips –– so that their travelers can focus on being productive and meeting in-person, not wasting valuable time booking travel. So in 2015, they created TripActions. Since then, we’ve been a mission to power the face-to-face, in-person connections that move people, ideas and businesses forward.

TripActions’ platform offers a vast selection of inventory that travelers can choose from, a personalized, intuitive user interface driven by machine learning, and 24/7 proactive real human, customer support. Companies enjoy complete travel program visibility, over 30% cost savings on average and seamless integrations with their HR and expense systems.

Globally, TripActions has grown to over 600 employees across 7 offices in 4 countries. We support over 1,500 customers, with innovative brands like Lyft, Dropbox, Sara Lee Frozen Bakery, Allbirds, Robinhood and the ACLU relying on TripActions for their business travel needs. As one of Silicon Valley’s newest “unicorns”, TripActions has a valuation north of $1B and a total of $232M in funding. We’ve recently received $154M in our Series C funding round –– led by new investor Andreessen Horowitz, with participation from repeat investors Lightspeed Venture Partners, Zeev Ventures and SGVC.

TripActions was recently recognized as one of Fast Company’s Most Innovative Companies for 2019, #12 in LinkedIn’s Top Startups 2018 and #3 in the U.S. for Happiest Employees by Comparably.

We’re redefining what it means to travel for work. Come help us build the future of business travel.
