GISA GmbH Tech Stack

SAP-native IT services for energy utilities, public sector, and industrial midmarket

IT Services and IT Consulting Halle, Sachsen-Anhalt 501–1,000 employees Founded 1993 Public Company

GISA is a German IT services firm built around SAP—the stack reveals deep domain specialization in energy and public-sector operations. Active S/4HANA migrations and smart-meter-gateway administration dominate the project list, while the engineering-heavy hiring skew (47 of 80 technical hires are engineers) suggests they're scaling delivery capacity for large systems implementations. The adopting/replacing pattern (S/4HANA, Fiori, SAP BTP) shows incremental SAP modernization rather than stack diversification.
