What our clients say about us

Lucien O'Donoghue
Lucien O'Donoghue Founder at Squaddy
FDT have an exceptional team. They hire selectively which is obvious when you begin working with them. Their development skills are first rate, as are their product/UI/UX skills. Don't have any hesitation about hiring them, they're awesome.
Farida Shakhshir Founder of SimSim Recipes
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.
daniel nicolson
Daniel Nicolson Managing Director at Cleversteam
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.
piotr czak
Piotr Czak CEO at PySENSE
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.

Tomasz Koprowski Marketing Director at Skra Bełchatów
On the sports market, mobile applications are not a new solution for communicating with fans.

An experienced team cooperated with a strong sports brand and the result is an effective marketing tool.
