Sigma is a group of leading consulting companies with the objective to make our customers more competitive. Our means are technological know-how and a passion for constantly finding better solutions.

Our services are provided by Sigma IT Consulting, Sigma Technology, Sigma Connectivity, Sigma Industry, Sigma Civil, and Sigma Software. Sigma Group is the parent company, developing and building the Sigma brand and our many framework agreements. Sigma Group is owned by Danir, a private investment company held by the Dan Olofsson family.


In 1986, entrepreneur Dan Olofsson started Sigma. To stretch the limits and try to create something lasting was a fascinating challenge. Was it possible to build a consulting company where substantial technical expertise could be combined with team spirit and the belief that it’s the team that wins? Was it possible to focus on both customers and employees while simultaneously running an effective and successful company? It was possible and since 1986 we have been adding one company after another to the Sigma Group. All of which are run with the same original focus on customers and employees.

We have made a remarkable journey and many have made important contributions along the way. We keep on moving and we keep on shaping the future and we continue to engage ourselves in new challenges.


It’s through “passion and execution” that Sigma makes a difference. As a privately owned company with a long-term strategy, we make all the decisions regarding our own development. We are growing and we are glad that more and more passionate people are joining us, shaping the future for our company as well as making a contribution for a better tomorrow.

For us at Sigma, these fundamental ideas are crucial:

  • We have substantial technical expertise and we love doing business. We make a difference through our participation and our dedication. We are proactive and we always look for new solutions. It’s what you do that counts – not what you say. We believe in getting things done.
  • We are extremely committed to everyone in our Sigma team. We believe in the strength of one added to another. The strength of this becomes even stronger when our different Sigma companies collaborate. We are characterized by our care for each other, for our customers, and for the world around us.
  • Our experience has taught us that it’s the ability to deliver that makes a difference. By working with interesting projects and clients, we grow as individuals and as a company. Through efficiency in our daily work we create resources that facilitate investments, which strengthens our operations. Our energy readily serves to advance our clients’ positions. Customer trust is what provides us with new commissions, which in turn makes it possible for us to take the next step forward on our journey.


Over the years we’ve come to realize that a commitment to making changes in our society is essential. The non-profit organization, Star for Life, is an example of this. We support them and their unique program aimed at preventing the spread of HIV and Aids among young people in southern Africa. The vision is to inspire schoolchildren to believe in their own futures and dreams, and to support their efforts to live a life without HIV. The project involves more than 100 000 young people and their families in South Africa and Namibia. We are a School Partner, which means that we are working with and supporting the school and the pupils at Dlilanga High School in South African Kwazulu-Natal, following the kids from the beginning to the end of a three-year program. Star for Life gives us a unique opportunity to provide hope for the future for children in southern Africa. And for us, as a company, to accept our social responsibility is good for everyone.
