Elektrosil

What Elektrosil does

Elektrosil GmbH is a Hamburg-based German electronics engineering and manufacturing services provider founded in 1983 (operating since the late 1970s), operating as a privately held GmbH since a 2019 Management Buy-out by Co-CEOs Hendrik Niemann and Hannes Collenburg. The company develops and produces customer-specific electronic and electromechanical system solutions, spanning the full product lifecycle from concept through design, hardware/software development, simulation, prototyping, validation, series production, and logistics services. Its proprietary product portfolio centers on the Smart-Knob and Smart-Switch rotary encoder/input device families (Mini, 360, and Diffus variants with configurable haptics and IP68 ratings), the patented climate seat automation system, wireless charging solutions, and the APUM phase switcher for EV charging infrastructure developed by Berlin-based subsidiary MCS Micronic.

Elektrosil generates revenue primarily through four streams: custom electronics development and manufacturing, standard component distribution, validation and testing services, and managed logistics/supply chain services. GTM is enterprise B2B direct sales with technical sales engineers and resident engineering support at customer sites, targeting major OEMs and industrial customers across seven verticals: Automotive (Tier 1 supplier to VW, BMW, Daimler; approximately 40% of revenue), Industry (including Siemens collaboration), POI/POS, Home Appliances, Transportation, Medical Technology, and E-Mobility. The operating model combines European engineering and quality oversight with Best-Cost Asia production partnerships, audited in-house under VDA 6.3 and IATF 16949 standards.

Customer relationships are anchored in long-cycle automotive and industrial programs requiring multi-year qualification under ISO 9001:2015, IATF 16949, KBA, and TÜV certifications. Core partnerships include Bühler Motor (joint online shop for DC/gear motors), MCS Micronic (wholly-owned embedded/e-mobility subsidiary), New Vision Display (displays since 2014), and Siemens (co-developed Smart-Switch). FY2018 revenue was reported at EUR 40+ million, the most successful year in company history at that time; the company continues active product launches through 2025-2026 with no disclosed external funding rounds.
