Holisticon Poland Tech Stack

Digital transformation and data platform services for mid-market enterprises

IT Services and IT Consulting Wrocław 201–500 employees Founded 2024 Privately Held

Holisticon Poland operates as a tech services firm within Nexer Group, combining two legacy brands (Sigma IT Poland and Nexer Insight Poland) under unified ownership as of 2024. The stack reveals a hybrid infrastructure play: embedded systems work (Asterisk, OpenWrt, SIP, DECT) sits alongside modern cloud-native tooling (AWS, Kubernetes, Terraform). The hiring velocity is accelerating with senior-weighted roles concentrated in engineering and data — a signal the firm is scaling delivery capacity rather than backfilling attrition. Active projects cluster around two distinct revenue threads: voice and IoT connectivity solutions on one side, and data platform modernization (lakehouse, governance, semantic layers) on the other.
