What CES does

CES (C.Ed. Schulte GmbH Zylinderschlossfabrik) is a German family-owned manufacturer founded in 1840 and headquartered in Velbert, Germany, with approximately 420 employees across seven generations of Schulte family ownership. The company designs and produces mechanical and electronic locking systems and access control solutions for residential, commercial, healthcare, educational, and public-sector buildings, with landmark reference projects including the Burj Khalifa, the Elbphilharmonie Hamburg, the Berlin government quarter, the University of Oxford, and 1&1's Montabaur headquarters. The product architecture is dual-track: a mechanical line built around the patented System DU 3D double-undercut profile (patent valid until 2031) and a family of security cylinders, mortise locks, and master key systems; and an electronic line comprising the AccessOne online access control platform, the CESentry cloud/web-based locking system, the CES OMEGA FLEX mechatronic platform, and supporting electronic cylinders, handles, furniture locks, wall terminals, and RFID transponder media supporting MIFARE DESFire and LEGIC advant standards. Additional offerings include the CESrelock construction-phase cylinder, a modular cylinder system, in-house galvanic surface finishing, and an S48 quick-delivery program (48-hour shipment for orders up to 100 cylinders).

CES operates a channel-mediated go-to-market model: authorized trade partners (Fachhandelspartner) receive patent-registered, exclusive customer profiles and order through a dedicated B2B trade webshop; a separate Objects department (Objektabteilung) handles large enterprise and public-sector project consultation; and a consumer-facing online shop (ces-shop.eu) sells the CESeasy Bluetooth Low Energy motor cylinder direct-to-end-users. Revenue is generated primarily through hardware sales of mechanical and electronic locking components, with an emerging recurring component from cloud-based management software (CESentry, CESeasy) and ongoing transponder media replacement. Marketing is conducted through multilingual websites (German, English, Dutch, French, Romanian), a HubSpot-managed CRM, and digital advertising on LinkedIn, Meta, and Google, supported by agency partner Midas Partners. The company is led by co-CEOs Bernd Becker and Dr. Frank Völker, with Prof. Dr. Hans-Georg Schnürch as Chairman of the Advisory Board; no external investors, funding rounds, or M&A activity were identified in the source data.
