Holisticon Connect (formerly Sigma IT Poland) is the Polish arm of Nexer Group, a Swedish-rooted global technology company. The operation combines local engineering with Nexer's wider capabilities across software development, cloud services, data platforms, and embedded systems. The company serves five core industries: automotive, healthcare/welfare tech, life sciences, manufacturing, and public sector—sectors where it claims experience in BI systems, infotainment platforms, IoT implementations, and legacy system modernization.
Services and capabilities
Holisticon's service menu spans six broad areas. Under AI, Data & Analytics, it offers AI agents, generative AI assessments, computer vision implementation, data governance, modern data platform implementation, and predictive maintenance. The company also conducts AI maturity assessments and strategy roadmaps, and provides a one-day generative AI assessment service.
In data visualization, it runs discovery workshops and builds custom visualizations. Custom software development includes web development and POC/MVP work. The cloud and operations portfolio covers cloud audits, consulting, development, migration and modernization, and CloudOps/DevOps services. Embedded software covers IoT/IIoT, embedded development, and connectivity services. A separate IoT, Cloud, Delivery & Enablement track offers a 10-week custom proof of concept, data scientist services, and delivery solutions architect roles.
The company explicitly mentions Microsoft Fabric as a platform it works with, suggesting Azure-based cloud architecture. It also advertises "Azure-powered generative AI" capabilities and has published whitepapers on AI agents in pharma and AI-enabled data visualization.
