SIT

What SIT does

SIT GmbH is a German private IT consulting and software company headquartered in Herrenberg, Germany, specializing in the HCL Domino/L Notes platform ecosystem. Founded in 1996, the firm operates with 11–50 employees under managing directors Ralf Simon and Heiko Voigt, and is registered as a private limited company (GmbH) under HRB 243748 at Amtsgericht Stuttgart. Its core competency is extending and modernizing legacy HCL Notes/Domino applications through a proprietary product family branded IMPRISIS, which includes REST APIs (IMPRISIS HDR), RichText handling (IMPRISIS RTA), an Apache Solr search module (IMPRISIS SC), a log analyzer (IMPRISIS LA), a React-based Single Page Application front-end platform (IMPRISIS DAP), an OIDC proxy for MS365, ZUGFERD/X-INVOICE electronic-invoicing compliance, and a point-of-sale system (IMPRISIS PoS). These are built on Node.js/Express and the HCL Domino AppDevPack, integrating IAM authentication and domino-db functions.

SIT also operates in two adjacent niches. First, FOKUS 5.0 is a specialized workflow-optimization solution for the German labor-court system (Arbeitsgerichte), featuring electronic case files, X/JUSTIZ-compliant data exchange, and secure mobile access via HCL Nomad on iOS and Android. Second, the firm delivers end-to-end IoT solutions spanning sensors (soil/air moisture, temperature, gas), network infrastructure (WiFi, LoRaWAN), data interfaces (REST, MQ), aggregation/analysis, and action models (IFTTT, Node-RED), with use cases in building automation, intelligent irrigation, wildfire early detection, air-quality measurement, and well monitoring. Beyond its proprietary products, SIT resells and provides services around HCL Notes/Domino, HCL Sametime, HCL Digital Experience, and HCL Connections.

The business model blends software licensing (IMPRISIS family, FOKUS, SIT Portal DXP, SIT Rent-A-Thing), professional services (project management, integration, IT architecture, application development, IT administration, IoT consulting), and hardware sales (IoT sensor packages). Go-to-market is primarily direct enterprise sales with regional concentration in Germany, supplemented by an HCL Technologies technology partnership, channel/distribution through the HCL partner network, a direct web shop (shop.sit.de), and self-service trial downloads for select products. The company markets via technical blogs (Dirks Blog and Heikos Blog), sponsors and exhibits at HCL ecosystem events such as Engage, and was recognized as an HCL Software Beacon Award finalist in 2016.
