Founded in 2018 in Santa Clara, xMEMS Labs has built a monolithic piezoelectric MEMS (piezoMEMS) platform that replaces traditional coil-based speakers and fans with fully solid-state silicon components. Its Sycamore loudspeaker is marketed as the world’s thinnest and lightest high-fidelity MEMS speaker for ultra-slim products such as AI glasses, headphones, and smartwatches. Complementing this is µCooling, the industry’s first chip-scale, vibration-free active thermal management solution aimed at smartphones, SSDs, and other space-constrained electronics. The company holds more than 250 granted patents and has earned accolades including Best MEMS Solution and Startup of the Year at Sensors Converge 2025. Major consumer OEMs are now engaging with xMEMS to integrate these technologies into next-generation edge-AI hardware. Proceeds from its latest funding will be used to ramp mass production, expand manufacturing partnerships, and fuel additional R&D on audio, thermal, and other piezoMEMS applications. The recently closed $21 million Series D round provides the capital required to support these scale-up efforts.
