We provide more functionality while using fewer resources by leveraging the latest technologies to develop platform independent software.

  • Designed to be platform independent
  • 80% of the app-code is reusable on all platforms
  • Native UI, native API access, and native performance

Web applications and web API's

We design and develop customized, browser-based solutions tailored to your individual requirements. We help you to integrate your web applications into existing systems and services through customized and powerful web API's.

  • Platform independent
  • No client side software installation required
  • Simple maintenance and extensibility

Agile Software Development

By employing agile software development approach, we guarantee that we constantly get your feedback to adjust to your needs. Wherever this may lead, we are with you to ensure the desired outcome.

Open Source Technologies

We not only use open source technologies, but also actively participate in their development and improvement.
