      Software Development Review from Daniel Rondell

      We are notably satisfied with the upshot. PMs and development team was very devoted to the tasks and encouraging. We had a stringent and fixed deadline. And we got it just in time! KitRUM helped us to create an entire software that absolutely meets our requirement. They had presented the system in a short-term after putting their hands on it. They also provide support after developing this software. We have a different project now and certainly will work with KitRUM again.

      5.0

      Software Development Review from Daisy Skot

      KitRUM made a variety of development services: conception, coding, and QA, which means almost a full software package for our company. We needed to develop a few tasks, for example, a desktop app for our store, a cloud app for administration and supervision, and a portable app for end customers. However, we had an in-house team, which is not enough for this project. So we had to find a dedicated team that could deliver all we needed. We found KitRUM as a top-notch software development company

      Software Development Review from Olena Shabunina

      We needed to quickly expand our dev team to build out a new feature set, and Hivex helped us find and bring on skilled remote developers to make that happen. The devs hit every deadline we set, sometimes even early. If we needed changes or had questions, they were super responsive - usually got back to us within a couple hours.

      We had a temporary gap in our technical team due to some transitions, and we needed to keep our development momentum going strong. Hivex provided us with skilled developers who seamlessly integrated into our team. They had the expertise we needed and filled the gap until we made permanent hires. Our collaboration with Hivex made sure our projects kept going without delay, we didn't lose our development momentum, and there wasn't any disruption. It was a huge help during a challenging time.
