Alyssa Franks
CO-FOUNDER OF MFA APPI am so glad, and so grateful that we partnered with TriState Technology. TriState has been with us from the beginning, looking at our very basic sketches and bringing all of that into a reality. The things I’ve loved best about working with TriState is that the communication has been consistent, reliable and fast.
RAHMAN KHAN & SISI CHEN
CEO & CO-FOUNDERI am Sisi from Netherland and we are very happy that we found TriState Technology LLP. They have developed our Android App, Flurry which is now online in Google Play Store. Our contact person Jay was professional, very flexible, he was also very easy to work. The development team did a very good job by completing the app, applying our questions, finding solutions that we have faced with the previous team. Even though there was the time difference, the communication was flexible. We are hoping that Android App would be a super success and will ask TriState to develop the iOS version App too.
