OUr values

We want to grow together with you by supporting your business and creating a relationship that would be beneficial for both parties. Most of our clients work with us from the beginning, as we help them develop and evolve by offering long-term solutions. We do not measure our clients by size or market share, we measure them by continuity and stability.

Our versatile, multilingual and multichannel contact center (call center) services can cover all of your company needs 24/7, 365 days a year. If you are looking for services that might include customer service, help desk, event registration or live-chat service – Katrium is the partner you are looking for, as our tailor-made contact center solutions and overall services are made exactly for your industry. If you need someone to generate leads, activate your past and existing customers, do cold calling and/or update your customer register – you are in the right place.

Our international and domestic market research services include qualitative and quantitative telephone interviews.
