A grown-up company
We want to do more than build great products. We want to build a great company. One that is environmentally friendly and supports the local community.
We are proud sponsors of: aparatus.si, podcrto.si, tomokriznar.com and several independently organized tech events around Slovenia.
3fs character
We’re just a bunch of people trying to build great products.

40 full time employees
From hardcore engineers to humanities and social sciences graduates. Our work is as diverse as our backgrounds.

5 flags
We currently consist of five nationalities: Mexican, Macedonian, Polish, Argentinian and Slovenian and work across 3 time-zones.

3 spin-offs
We like to see projects take on a life of their own. Toshl, Toonia and Tricky Tribe all started as small internal projects. Now they are their own companies.
Tools we use
We try to pick the tools that will help us build the best possible product rather then be hung up on sentiment. But to give you an idea of our competency, these are the tools we’ve been using often lately:
Go, PHP, Swift, Objective C, Unity, Java, CoreOS and Docker
Our awesome partners
Over the years we’ve established close relationships with some great companies.
