Siletra is a web agency with more than ten years of experience in providing various internet-related services. Our activities range from creating websites and other web solutions to internet marketing, web design, internet-related education and developing custom applications. In the past ten years, our team has successfully completed almost 250 projects, most of them websites. In our work we value tangible and measurable results that benefit our clients.

We prefere to become a global design company committed to creating positive impact. We are a community of designers, entrepreneurs, engineers, teachers, researchers, and more. Our shared values and beliefs influence the work that we do, and the impact we
hope to achieve.

As pioneers of human-centered design in Slovenia, we keep people at the center of our work. It’s a key tenet of design thinking, and even as our methods evolve in response to new, complex challenges, we’re always designing solutions for people first.
We’re building to learn, and learning as we build, through inspiration, ideation, and implementation.

  • Everyone is creative.
  • Creative organizations are more agile.
  • Complex problems are best solved collaboratively.
  • Innovation starts with people.
  • Technology moves fast, human needs change slowly.
