I have gone through an infographic. Even I had a conversation with many IT companies and even browse many resources. As one of it is this. But here I think few information lack i.e Outsourcing vs In-house, Post Release Cost, How to Reduce Development Cost. Although this infographic is available with many information.

I’m good with Lyft, Curb, Hailo, Gett, and Juno (you should mention that Juno works now under the banner of Gett).
