We got introduced to GrayMatter through Arprotec, a leading ICT solutions provider in Latin America. It has been a wonderful experience working with the GrayMatter team. I have found them to be extremely professional and receptive to our needs. While their key credentials come in from airport domain expertise and a globally proven data analytics track record, I would also like to commend their work ethic and attitude. I must also add that Arprotec has been very proactive and responsible towards making this tripartite association work.
