Özgur Coban Founder at FERMO Food
FiveDotTwelve is more like a team than an agency that you just hire. Great understanding of the product and my vision. They were really supportive when I needed that, and also when I wasn’t expecting any assistance from them at all. I highly recommended FiveDotTwelve.

Tomasz Koprowski Marketing Director at Skra Bełchatów
On the sports market, mobile applications are not a new solution for communicating with fans. However, it is rare for a service provider to create a fully dedicated product for a club, which is exactly what happened in case of this project. An experienced team cooperated with a strong sports brand and the result is an effective marketing tool.
Oni Banurji Co-founder at DinerMojo

Their communication was the most impressive thing about them. They not only waited for input from us but also proposed solutions. They were our partner, not just a team doing what they were told.

Piotr Jarząbek Founder at WeAreBikers
I recommend FiveDotTwelve for everyone who are not fond of hearing “it can’t be done”. The team successfully managed to develop my app ideas, often advising on how the functions could be improved. If it wasn’t for FiveDotTwelve, my project probably wouldn’t have seen the light of day.
