What STORK does

STORK GmbH is a privately held German industrial services and machine engineering company headquartered in Billigheim (Rittwiese 29) operating from a 1,500+ sqm facility with up to 12-ton crane capacity. The company was formed in 2020 through the combination of STORK Maschinenüberholung GmbH, which carried 40+ years of machine overhaul heritage, and STORK Motion GmbH, which brought special machine construction and automation experience. As the official authorized partner for both Liebherr and Liebherr-Lorenz, STORK delivers machine retrofits, overhauls, spare parts, preventive maintenance, safety assessments and CE marking, custom Sonderkonstruktionen, precision parts manufacturing, and software and control system services (including the proprietary StorkGear CNC programming tool and control replacements up to Siemens One with StorkGear 21.0). It also offers a CO2 certification add-on that documents 12 tonnes of CO2 savings per machine tool under Greenhouse Gas Protocol methodology.

The underlying technology is rooted in mechanical retrofit engineering with proprietary software and a new precision cut-off grinding machine (the Rawyler successor) capable of >=1,000 cuts per hour at >=95% availability on difficult materials including Inconel. Complementary capabilities include CAD E-Plan control cabinet construction, SISTEMA calculations, gear data calculation, and 3D modeling for full-cycle custom machine delivery from concept to commissioning.

The business model is sales-led and project-driven: customers contact STORK directly by email ([email protected]) for bespoke quotes, with revenue split across one-time project fees for retrofits and custom construction, recurring maintenance subscriptions, spare parts supply, professional services (CE/SI), and software/control engineering. The customer base spans large corporations to small businesses across general manufacturing, served primarily in the German market with cross-border reach via international partners Jone Engineering (France) and WOLFGRIPP (Poland). Three managing directors — Andrea Kübler, Doris Schmiedt, and Björn Hedrich — lead the firm, which holds ISO 9001:2015 certification and received the Rolls Royce Maintenance Award in 2019; it is currently investing in talent pipelines through a Mechatronics apprenticeship starting September 2025 and a planned DHBW Mosbach co-op program from Winter 2026.

Direct peers

• Klingelnberg: Germany-based leader in gear cutting machines, gear measuring equipment, and gear technology with service and retrofit operations for legacy installations. Operates in the same gear-cutting machine space as STORK, often serving overlapping automotive and industrial drivetrain customers in the DACH region.
• Gleason Corporation: Global leader in gear technology manufacturing gear cutting and finishing machines (including legacy Pfauter) with field service and aftermarket support. Its aftermarket service and retrofit capabilities for installed Gleason/Pfauter machines are directly analogous to STORK's authorized-partner role for Liebherr and Lorenz equipment.
• Samputensili (Macno Group): Italian-based manufacturer of gear cutting and grinding machines with service capabilities for legacy installations. Operates in the same gear cutting machine service domain as STORK, frequently serving overlapping European automotive gear manufacturing customers.
• Heller GmbH: German-based machine tool specialist providing manufacturing and refurbishment services for CNC machining centers. Its retrofit and upgrade business model focused on Heller-installed bases mirrors STORK's authorized-partner approach for Liebherr/Lorenz machines, including control modernization and lifecycle extension.

Broad incumbents

• INDEX-Werke: German manufacturer of turning machines and turnkey manufacturing systems with field service operations for installed bases. While the product focus differs (turning machines vs. gear cutting), its aftermarket retrofit service model for legacy installations aligns with STORK's lifecycle-extension work.
• TRUMPF: Major German industrial machinery manufacturer with extensive service and retrofit offerings across metalworking equipment. Operates as a broad industrial machinery incumbent with comparable after-sales/retrofit capability to STORK, though at materially larger scale and across broader machine categories.
• Mitsubishi Heavy Industries Machine Tools: Japan-based global conglomerate whose machine tool division manufactures gear cutting equipment (formerly Drycut and Mitsubishi Gear Technology). Provides aftermarket service for an installed base comparable to STORK's, particularly serving automotive and heavy-industrial gear manufacturing customers in Europe.
• DMG MORI: Global leader in machine tools with extensive service network across European manufacturing. While primarily a new-machine manufacturer, its large aftermarket services business for installed bases provides an analogous retrofit competitor for multi-brand industrial customers requiring lifecycle support.
• EMAG Group: Large German machine tool group offering turnkey manufacturing systems for gear cutting, turning, and grinding with comprehensive field service. Covers a substantially broader machine portfolio than STORK but provides comparable retrofit, control modernization, and lifecycle-extension services to industrial customers across Europe.

Others

• Liebherr: OEM manufacturer whose gear cutting machine product lines (L, LC, LCR, LCS, LE, LF, LFS, WS, WSC; Lorenz SV00, S360, SN, LS, MCS series) form STORK's core authorized-service addressable base. Represents both STORK's largest opportunity (substantial installed base) and primary concentration risk (sole OEM partnership).
