AlpSemi, a Grenoble-based semiconductor startup, has raised €17 million in a funding round led by Yotta Capital, with participation from SE Ventures, Navitas Semiconductor, and Cycle Group.

The company develops semiconductor power switches designed for solid-state circuit breakers used in residential and commercial buildings, as well as 800V DC AI data centers. AlpSemi said the new capital will be used to support industrialization, commercial scale-up, and broader commercialization of its first product, the AS800.

The raise comes as demand grows for more digitally controlled power protection systems across buildings, industrial electrification, and data center infrastructure. AlpSemi is positioning its technology as part of that shift, targeting applications where efficiency, scalability, and integration into existing power semiconductor value chains are increasingly important.
