Tailored IT.

For everyone
who expects more.

We begin where standard software reaches its limits.

collana solutions develops bespoke software solutions for businesses that see digitalisation not as a duty but as a strategic advantage. Our mission: not just to digitise processes, but to deliver real differentiation, efficiency and long-term value.

We don’t see ourselves as a conventional service provider, but as a long-term technology partner. Our projects are based on close collaboration – agile, reliable and always focused on one thing: measurable impact.

Three specialists,
one solution unit

collana solutions brings together the expertise of three well-established companies within the collana IT Group – with a combined 70 years of experience:

Experts in web development,
complex platforms and Microsoft technologies

Partners for custom software,
interfaces and data-driven IT projects

Specialists for mobile processes,
app development and IoT integration

Our drive is still the same – even under a new name. We approach our work with the same values as before: a strong commitment to quality, open and collaborative dialogue with our clients, and the belief that technology works best when it’s tailored. We listen, ask the right questions, and apply our know-how to deliver solutions that truly fit – exactly where standard software reaches its limits.

What connects us, stays.

Even with a new name, the things that define our way of working remain unchanged: personal connection, short paths and trusted collaboration. Now operating as collana solutions, we continue to do what we always have – with the same people, the same mindset, and the same dedication to your success. Your familiar contacts are still here for you. We understand your needs, speak your language and deliver with the same reliability and expertise.

New name, same trusted people

We understand your business, we speak your language – and we remain fully committed to delivering the solutions that move you forward. Our management:
