We have been working closely for more than 4 years now! It's a great partnership between us as well as their team members who are always there to help you out whenever needed. Nothing much so far but I am sure this will change once we get into implementation phase of our project. The only thing that comes across my mind right away is they charge too high rates compared to other competitors which makes it difficult sometimes when budgeting projects. They do provide good support services though. Great partners - Highly recommended!! Project management / Data collection & Analytics platform.
