What Seskion Gmbh does
Seskion GmbH is a privately held German engineering company founded in 1997 and headquartered in Leinfelden-Echterdingen. The company designs, develops, and manufactures the Simulyzer family of hardware instruments and companion software used to simulate, analyze, and test automotive sensor-bus protocols in development and production environments. Its portfolio addresses PSI5, DSI3, SENT, and SPI in-vehicle sensor interfaces through a range of products: compact bench-top units (PSI5-Simulyzer, DSI3-Simulyzer, SENT-Simulyzer, SPI-Simulyzer), the multi-channel Simulyzer-RT rack system, the PSI5 POD conformance tool, and the SQUIB Box for airbag squib/pyrotechnic device testing. The hardware is built on custom PCB designs and programmable FPGA logic, paired with protocol-aware PC software (including PSI5 v2.6.28.2 and DSI3 v1.8.20) that supports measurement, Hardware-in-the-Loop simulation, EMC testing, and sensor validation workflows.
The company sells primarily to automotive OEMs and Tier-1 suppliers — its named reference customers include Audi, BMW, Bosch, Continental, HELLA, and ZF, with adjacent industrial customers such as STÖBER Antriebstechnik. The go-to-market combines direct enterprise sales in Germany with a network of distributors covering China, Taiwan, Japan, and South Korea, indicating a deliberate focus on the German automotive core while extending reach into key APAC electronics and vehicle manufacturing hubs. Revenue is generated through a mix of hardware unit sales, software licenses, and custom engineering services for protocol integration and test automation. Seskion holds ISO 9001:2015 certification and is an Associated Member of the PSI5 standardization organization, supporting process maturity and engagement with industry protocol governance.
