Navan About Us

Navan is the all-in-one super app that makes travel and expense easy so you can focus on being there, not getting there. Say goodbye to spending hours on the phone trying to change your flight or saving stacks of receipts to manually input expenses. From EAs and finance teams to travel managers and employees, Navan empowers people to focus on the things that matter most to them — all while providing companies with real-time visibility, savings, and control.

Navan’s investors include visionaries like Andreessen Horowitz, Lightspeed Ventures, Greenoaks, Zeev Ventures, and entrepreneurs Lee Fixel, Adam Bain, and Elad Gil. Valued at $9.2B, Navan is well-positioned for continued growth as it continues its takeover of the travel and expense market.

In April 2023, Navan expanded in the Indian market with the acquisition of Tripeur, a modern, people-centric corporate travel and expense management company. The group’s fifth acquisition in under two years, Tripeur joined the Navan Group alongside Spanish meetings and events specialists, Atlanta Events & Corporate Travel Consultants; Berlin-based modern travel management company, Comtravo; leading Scandinavian travel agency Resia AB; and London-based high-touch TMC, Reed & Mackay — the latter of which remains a standalone brand.

At Navan, we’re never satisfied with the status quo, and we know breakthrough ideas come from diverse perspectives. We are committed to cultivating a workplace that reflects the diversity of the customers we serve while fostering leadership and innovation. All voices are valued here and you’ll have the resources, tools, and training you’ll need to do the best work of your life.
