Uber, as we know, operates only in 650 cities and remains the best among all taxi apps. But have you ever imagined about other cities and their demand for taxi applications? If you did, you would have certainly come across a few regional apps like Ola, Didi Chuxing, Japan Taxi, etc. These apps are focused on fulfilling the demands of locals; and in that way, they have succeeded and generated revenue tremendously. If you search for the reason behind the success of these apps, it inevitably ends up in the kind of service it provides its customers. So, it all depends on how well you bestow your service (whether you focus regionally or globally).
