xMEMS

xMEMS is a Santa Clara semiconductor company that builds sound and cooling out of silicon. Its piezoMEMS platform produces the world's first solid-state MEMS loudspeakers - all-silicon drivers with no moving voice coils - for earbuds, hearing aids, AI glasses and headphones, and the first 'fan-on-a-chip' active micro-cooling device that moves air inside phones, wearables and AI data-center optics. Founded in 2018, the company holds more than 300 patents and has raised roughly $129M across four rounds.
