What our Clients say about us

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.

Farida Shakhshir Founder of SimSim Recipes

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.
