xMEMS Labs, the inventor of the world's first piezoelectric MEMS (piezoMEMS) µCooling fan-on-a-chip thermal management solution and the leader in solid-state silicon speakers, today announced the closing of a $21 million Series D funding round. The round was led by Boardman Bay Capital Management (BBCM), with participation from Cloudview Capital, CDIB-TEN Capital, Harbinger Venture Capital, SIG Asia Investments, an affiliate of Susquehanna International Group (SIG), and other strategic investors.

Founded in January 2018, xMEMS Labs is the 'X' factor in MEMS with the world's most innovative piezoMEMS platform. It began by delivering the world's first solid-state True MEMS speakers for TWS and other personal audio devices and evolved its substantial IP to produce the world's first μCooling fan on a chip for smartphones and other thin, performance-oriented devices.
