Uber is a transportation network company that offers ride-sharing, taxi, and food delivery services through a mobile app. Founded in 2009, Uber grew rapidly but faced scandals and leadership changes that slowed its growth. It is now letting go of over half a billion potential riders in Southeast Asia by selling its operations there to Grab and taking a large stake in the rival company, in an effort to recover from $4.5 billion in losses last year. This could give Grab an advantage over its rival Go-Jek in the region by acquiring UberEats.
