Uber pays –$29M/year for Google Maps
sec.govHere is the actual contract https://www.sec.gov/Archives/edgar/data/1543151/000119312519... It includes other topics like Uber has to share their location data to Google and can not use any other 3th party provider at the same time as Google Maps.
Holy crud: "Android Devices. Within [] after the Maps APIs Addendum Effective Date, Customer will make commercially reasonable efforts to standardize on Android-based devices for at least [] of new, Customer-purchased devices issued by Customer to Uber Drivers. Customer may select the specific Android-based devices, and they may vary by region."
Seems like they would want go the amazon route and bring a lot of that in house to cut costs and possibly create a revenue center.
