I've worked with them to develop my first app for an internal use case - it was very well managed by their team of specialists (and we're talking about people who have over 20 years experience between themselves). They were really helpful throughout our engagement until launch day! Their support is top notch as always but there isn't anything that needs particular attention from me here apart form just being aware when things are off track :) Great folks all around at CR which makes working through some complex problems easy!
