What Kessler systems GmbH does
Kessler systems GmbH is a German Electronic Manufacturing Services (E²MS) provider headquartered in Ostrach, Baden-Württemberg, founded in 2010 by Marc P. Kessler. The company delivers end-to-end electronics contract manufacturing — electronics development (hardware, firmware, software, mobile apps), PCB procurement and fabrication up to 22 layers, SMD/THT assembly across 40 production lines capable of placing up to 4 million components per hour, prototype building (EMSPROTO®), device construction, HMI display and touch solutions, testing, refurbishment, fulfillment, and obsolescence management — targeting industrial, IoT, aerospace, automotive, medical technology, defense, and agricultural customers.
The group operates four wholly-owned subsidiaries: kessler engineering GmbH (development services), kessler licht technik (lighting), EMSPROTO® (startup prototyping), and Soluware GmbH (software development, acquired November 2025). Manufacturing is anchored in Ostrach with additional capacity in Ravensburg and historical sites in Königseggwald and Pfullendorf. The asset base is certified to ISO 9001, IATF 16949, ISO 14001, ISO 27001, ISO 45001, and IPC-A-600/A-610 standards, and includes AOI/X-Ray inspection, cleanroom assembly, selective and wave soldering, and in-house test-fixture building.
Revenue is generated through project-based and per-unit manufacturing fees, long-term service/refurbishment contracts, and component procurement margins under a quote-based pricing model with no minimum order quantity (orders from 1 unit). Distribution is direct via an enterprise field-sales team, the my.kessler customer portal, industry trade shows (notably embedded world in Nürnberg), and strategic referral channels including the Schulz Group partnership and industry associations (WVIB, TIM, ZukunftTier). The Schulz Group acquired an equity stake in November 2025, providing growth capital while the Kessler family retains operational control through Managing Director Marc P. Kessler.
