99 claims to be the market leader vs. Uber in Sao Paulo and Rio de Janeiro, with 140,000 registered drivers in Brazil and over 10 million app downloads. A spokesperson for Uber declined to comment on the deal. 99?s previous investors include Tiger Global, which has put money into both Didi and Uber, along with other ridesharing firms. It launched in 2012 as a taxi-hailing platform but has added black car and peer-to-peer services since then. Uber has not only faced competitors like 99, but also fierce protests in Brazil and other South American countries over the last couple of years.
