Sigma Technology Software Solutions welcomes Patrik Stjerna as the new unit manager in Karlskrona. With more than two decades of leadership experience in IT and a strong local network, Patrik will lead Sigma’s expansion in Blekinge with the aim of making the company the region’s largest consulting partner.
Sigma Technology is strengthening its presence in Karlskrona as Blekinge increasingly establishes itself as a hub for tech consulting. The region brings together expertise in software, cybersecurity, telecom and defense, supported by Blekinge Institute of Technology (BTH), which supplies a steady stream of talent from more than 7,000 students. With a favorable business climate and good transport and commercial ties to Poland, Germany and Denmark, Karlskrona provides a strategic base for national and international growth.
“Blekinge has the mix we need to grow: ambitious customers, skilled engineers and a business culture where things get done. We already support many clients across southern Sweden and see increasing demand across several segments and industries. We welcome Patrik Stjerna — his track record in these areas will help us scale delivery from Karlskrona and Karlshamn and build the region’s strongest consulting team,” says Toni Risteski, CEO of Sigma Technology Software Solutions.
Karlskrona-based leader Patrik Stjerna, who brings over 20 years of experience in senior roles across IT, hosting, telecom, manufacturing and electronics, has a clear mission: to build the region’s strongest consulting team and help clients accelerate innovation and secure the right talent faster.
“My first months in Karlskrona will be focused on laying a strong regional foundation. Blekinge is growing rapidly, and my ambition is to support that growth with top-tier expertise to meet rising demand for software development, innovation, cybersecurity and AI. The goal is clear: to create and provide a high-performing, cohesive team that grows with our clients and strengthens Sigma’s position as Blekinge’s leading consulting hub,” says Patrik Stjerna, unit manager at Sigma Technology Software Solutions.
The units in Karlskrona and Karlshamn will form a high-capacity delivery center for both existing and new customers. By combining senior expertise with a strong talent pipeline from BTH, Sigma aims to scale up, deliver faster and more specialized solutions, and help position Blekinge as one of the Nordic region’s most recognized hubs for innovation and technical leadership.
