Your team in Stuttgart.
Germany is Europe's largest market, and the south around Stuttgart is its engineering heartland. Korean companies working here need software and IT that meet German rules and still connect to headquarters in Korea. We meet in person in the Stuttgart region, work in English and German, and take care of the German side.

In which language do you work?
We work in English and German. The software we build can be fully in Korean, and we can prepare Korean user interfaces and guides with your team.
How does the time difference work?
Germany is 7 hours behind Korea in summer and 8 in winter. Our morning is your afternoon, so we have shared working hours every day.
How fast can we see results?
Usually a working first version within a few weeks. After that, new versions arrive in short rounds.
How do you price projects?
After a free call you get a written proposal with the scope and a fixed price for the first phase.
Can you support our team in Germany?
Yes. We are based in Stuttgart and can meet in person, work with your local team and handle German requirements like GDPR and e-invoicing.
