"They have a huge amount of knowledge."
The core of our business, a mobile app and server, were created by Vincit.
Our collaboration has worked really well. We have received software that matches our specifications. There have been many changes along the way, and Vincit has been flexible in their implementation.
If something is unclear, Vincit does not immediately go back for help. They have a huge amount of knowledge in-house, and they share it effectively.
I can wholeheartedly recommend Vincit if someone asks me for a competent software firm.
