The end users liked that the app was user-friendly and functional. The team was available and always ready to resolve the client's issues. Overall, their level of commitment was top-notch.”

“They focus on working with nonprofit organizations even if the funding streams are a little shaky. We don’t have continuous revenue to pay for a contract up front, so Grey Chain has been really flexible with our payment schedules. We let them know our annual budget can’t exceed a certain threshold, and they work with their management team to adjust the numbers to fit our budget. Overall, their cost for technical quality is always amazing.”
