LAMMERZAHL

What LAMMERZAHL does

LÄMMERZAHL GmbH is a privately held, founder-owned German software company headquartered in Dortmund that has specialized in social-administration software since its 1987 founding by brothers Jürgen and Rainer Lämmerzahl. The company develops and sells the LÄMMkom suite — an integrated platform built on Progress Software infrastructure — whose flagship product LÄMMkom LISSA covers all administrative processes for German municipalities under the Social Security Code (SGB II, VIII, IX, and XII), plus adjacent legal areas including Wohngeld, Asylbewerberleistungsgesetz, and Unterhaltsvorschussgesetz. The suite is modular, with add-on products for document management (DOKUMENTE), business intelligence (ANALYSE), low-code digital citizen applications (ANTRAGSMANAGER, co-developed with Wolters Kluwer), maintenance-law calculation (UH-LEX, co-developed with Lammers Dülmen), training (KOLLEG), annual user conference (TAGUNG), and hosting/support services (SERVICES).

The company's revenue model combines multi-year enterprise software licensing (subscription/recurring) to German public-sector clients with implementation professional services, training revenue (workshops and seminars), and managed services including ISO/IEC 27001:2005-certified cloud hosting and GDPR-compliant data-processing contracts. Go-to-market is primarily direct enterprise sales to Kreise, Städte, Ämter, and Gemeinden, supplemented by channel partnerships with regional rechenzentren such as KDO, and reinforced by a sticky customer community organized around the long-running annual Anwendertagung (26th edition in May 2026). The company serves over 400 municipal customers exclusively in Germany, with no disclosed geographic expansion outside the domestic public sector.

Operational and competitive positioning is supported by domain depth (35+ years of continuous SGB-specific development), regulatory certifications (first-mover ULD data privacy seal from 2003, ISO/IEC 27001:2005 hosting certification from 2010, and ongoing GDPR compliance attestations), and family ownership that explicitly avoids external capital. The company has completed an organizational development project and continues to launch new product modules at regular intervals, indicating sustained operational investment within a mature, stable competitive footprint.
