They love working on our projects, and they enjoy what they do. Most developers don't like to work on other people's code but FiveDotTwelve has been very open to that. Thanks to them, we didn't have to rewrite the app's code. They're also timely, which is why we have a very good relationship.

FDT have successfully helped across several different projects. They have been able to provide a personable and human approach to outsourcing. Their developers integrated into our team on one project whilst on another they were able to take a specification and independently deliver the final product. Would highly recommend.

Our joint project with FDT resulted in outstanding results for our company. We achieved all business goals in given schedule and budget. On development level, the agile approach proposed by FDT, helped us to have a full control on our project. On personal level, working with Damian and his goal-oriented team was an exciting journey which was a pleasure not a daily routine. Hopefully, we can work together in the future.
