I worked with Symphony in my previous position and when founding Graphyte and looking for a software development partner I had no hesitation in getting in touch with Theo, the founder of Symphony. We have subsequently built a small multi-discipline team that has taken the platform from concept and POC to a well developed, fully supported platform. The management are always very transparent in their approach and open and honest in communications and this helps us to make the team feel a part of our company rather than just an outsourced function. The quality of resources that we have brought into the team has been great and we have been able to add additional skillsets relatively quickly and easily. I would definitely recommend using Symphony for any nearshore development projects that you might be looking at.

Web DevelopmentSoftware Development

We work with Symphony Solutions since 2012. They take care of all our web and software development, IT services and product design. Symphony Solutions is a reliable partner and their communication complemented their highly professional management style. Each time we present them a new project or change, the employees are very helpful and proactive. They think along, provide useful feedback and come up with new, better ideas. While working with Symphony Solutions, I´ve got the impression that they consider the projects as their own, and that they´re working not just to respond to our requirements, but to build a successful product that will solve the users´ needs. I highly recommend this company to anyone that is searching for a reliable IT partner.
