      Software Development Review from Martin Macmillan

      Codebludev was able to take our vision and help us deliver an app that empowers retail shareholders to make their voices heard. Theyve brought a depth and breadth of technical expertise and user experience design to challenge us on our assumptions on how people would want to interact with the app. From a mobile development perspective, we wanted to go to market with both an Android and an iPhone simultaneously.
