Our services
Many of our clients want us to handle the whole project, while others only need certain aspects. Here’s the full run-down of our services:
We’ve been on the front line for many newborn startups, armed only with an idea and endless enthusiasm. We’ve seen some brilliant decisions – and some not-so-great choices – and all that experience has taught us that strategy and research is vital.
Through workshops and modern research methods we’ll test your idea, make sure it fits the market and show you how to turn it into reality. We’ll lay the foundation before writing a single line of code.
Through our 4-stage process we’ll make sure all bases are covered.

Quality assurance
Many brag about senior developers but forget to mention quality assurance. That’s where they try to save money. We don’t.
What truly sets us apart are our QA engineers and processes. Enterprise-grade software requires quality assurance at the highest level.
Here’s why our QA works so well:
- Code reviews
- Code guidelines
- Test automation
- UI tests
- Code quality tools
- Unit tests
Our passion for quality assurance also led us to build our own crash and bug reporting tool
