What Our Clients Say

Intersog was chosen for a number of reasons. Firstly, their previous work was really good; secondly and more importantly – they seemed to be genuinely interested in my app idea and concept. Also, Intersog didn’t look like a company that would just do work and say good-bye. I’m happy with my choice and have never regretted making it.
Jack Turner, Founder & President, Ski Nation
We’ve had a challenge finding qualified PHP resources; now we’re able to find these resources quite quickly with Intersog. Our team in Munich is responsible for the project and works with the Intersog teams in Ukraine to get it done.
Jörg Strathaus, CTO, Travian Games
Due to the successful code unification done by Intersog, we are able to support multiple web products for different market segments using a single platform, while benefiting from improved data structure and visualization.
Project Manager, SAM Learning Go!
Not only did Intersog’s QA team help us with removing more than 2,400 bugs from our code, but they proposed important features that were later implemented into our code. Intersog’s programmers also helped us with implementing an innovative Self-Service feature.
