About
Siemens is a German technology and industrial conglomerate founded in 1847 by Werner von Siemens, one of the oldest and most broadly diversified technology companies in the world. Today the company's focus is concentrated in two high-growth segments: Digital Industries, which provides automation, industrial software, and manufacturing execution systems; and Smart Infrastructure, which delivers grid technology, building automation, and electrification solutions. Siemens' core technology platform, the Siemens Xcelerator open digital business ecosystem, connects hardware, software, and services into an integrated industrial AI and automation layer.\n\nSiemens' product and solutions portfolio spans factory automation (PLCs, drives, robots), simulation and digital twin software (through Siemens EDA and Siemens Opcenter), building management systems, power grid components, and electrification infrastructure. Its industrial software business — including the NX CAD/CAM suite, Teamcenter PLM, and MindSphere industrial IoT platform — serves aerospace, automotive, electronics, and energy companies managing the complexity of modern product development and manufacturing operations.\n\nSiemens generated €75.9B in revenue in FY2024, a 3% increase, and reported €19.4B in Q3 FY2025 revenue, up 5%. The company has positioned itself as a leader in the industrial AI and automation megatrend, investing heavily in AI-augmented manufacturing tools and smart grid technology needed to support the global energy transition. With a $100B+ market capitalization and deep relationships across global industry, Siemens is well positioned to capture the digitization and electrification capex cycle accelerating through the late 2020s.
