What we can tell you is that Valor Software is very, very knowledgeable and very helpful. We think what sticks out the most is their capacity to find solutions instead of just saying what cannot be done. They know how to develop any feature that we request, and they are very good at user experience. They also know how to communicate with non-tech people. I think that makes them quite special because any client can communicate with them.
