When most people hear "solid-state," they think storage. But in Santa Clara, xMEMS Labs just gave that term new resonance, literally. The company just raised $21M in Series D funding led by Boardman Bay Capital Management, with Cloudview Capital, CDIB-TEN Capital, Harbinger Ventures, Susquehanna Asia Venture Capital, and other strategic investors tuning in. This isn't another round of capital, it's an #amplifier for a company turning silicon into a new language of #sound and #cooling for the AI era. Founded in 2018 by Joseph Jiang and Jemm Liang, xMEMS spun out of piezoelectric R&D at TSMC and turned what was once wafer-level theory into commercial hardware. Joseph Jiang, a veteran of Knowles, Fortemedia, and InvenSense, leads with precision and swagger, while Jemm Liang, who built Ultrachip from the ground up, drives the engineering with surgical focus. Co-Founder & CLO Wei-Fu Hsu, the former MediaTek exec and IP expert, ensures xMEMS' innovation is as protected as it is disruptive. Their play? A monolithic MEMS platform that transforms voltage into vibration, silicon into sound. Unlike legacy coil speakers and fans, xMEMS tech doesn't move parts, it moves markets. Over 500K MEMS speakers shipped in 1H'24, backed by >250 global patents. The Cypress & Sycamore lines redefine what "small" can do: 1mm-thin, full-range, and capable of sub-bass response once thought impossible in earbuds. Their XMC-2400 µCooling chip, 1mm-thin, fan-on-a-chip, inaudible, moves 39cc/sec of air at just 30mW. That's not cooling, that's choreography at a molecular level. Dr. Chester Hwang, named CTO on Oct 15, 2025, joins to push that curve further. Alongside veterans Mike Housholder (VP Marketing & Biz Dev), Jim Wargnier (VP N.A. & EU Sales), James Lee (VP & Korea GM), Steven P. Bentley (VP Sales), and Martin Lim (VP MEMS Tech), xMEMS is scaling at semiconductor speed. They're already in BleeqUp's AI sports glasses and teamed with Dongguan Rayking Electronics for TWS modules. When OEMs talk "next-gen," they're talking xMEMS-level integration. For investors like Boardman Bay's Will Graves, this isn't just sound engineering, it's signal intelligence. With AI pushing devices thinner, faster, and hotter, xMEMS' piezoMEMS platform sits at the intersection of #acoustics and #thermals, where every millimeter matters. Backing them is a bet that the next wave of #sensorytech won't just compute, it'll feel alive. So what's next? Scaling production, expanding capacity, and embedding xMEMS' silicon pulse into everything from earbuds to AI #datacenters. In a world chasing speed, silence, and fidelity, xMEMS isn't following the beat, they're building the frequency the future will hum to. #Startups #StartupFunding #VentureCapital #SeriesD #AI #Sound #SoundEngineering #Semiconductors #Data #DataDriven #Technology #Innovation #TechEcosystem #StartupEcosystem #Hiring #TechHiring If software engineering peace of mind is what you crave, Vention is your zen.

US-based ChipAgents.ai has raised $21 million in a Series A round to transform semiconductor design with agentic AI. ChipAgents has developed an AI platform to automate routine chip design and verification tasks. As semiconductor complexity skyrockets, its technology assists engineers by cross-checking specifications, generating code, and creating test benches in minutes instead of weeks. This allows design teams to focus on innovation and shorten time-to-market. The round was led by Bessemer Venture Partners, with strategic backing from Micron Technology, MediaTek, Ericsson, ScOp Venture Capital, and Amino Capital. The funding will fuel R&D and enhance on-the-ground customer support for its semiconductor clients. Congratulations to founder and CEO William Yang Wang and the ChipAgents.ai team.

Intel in Talks to Acquire AI Chip Startup SambaNova Intel is reportedly in talks to acquire AI chip startup SambaNova Systems, according to Bloomberg. The potential deal may value SambaNova at below its prior $5B valuation, signaling ongoing consolidation in the AI semiconductor sector. SambaNova, backed by Intel Capital, SoftBank Vision Fund, and Walden International, develops custom AI processors aimed at accelerating large-scale model training and inference. If completed, the acquisition could support Intel’s push to rebuild its position in the AI GPU and accelerator market, an area still dominated by Nvidia. With global investment flowing into AI infrastructure and sovereign computing stacks, this move would further highlight the competitive race to define the next generation of AI hardware. #Intel #SambaNova #AIChips #Semiconductors #AIInfrastructure #Nvidia

Quantum Brilliance has opened a new facility at Melbourne’s Notting Hill, where it will make lab-grown diamonds for quantum computing devices. According to a statement on Wednesday from state economic growth minister Danny Pearson, who opened the foundry this morning, it will see world-leading technology developed to enable portable quantum devices that are able to work at room temperature. The Victorian Government has supported QB through its venture organisation, Breakthrough Victoria, which made an investment of $8 million and a follow-up investment of $10 million in the startup. The company was also one of the first backed by the National Reconstruction Fund Corporation, which invested $13 million in the foundry in December last year. https://lnkd.in/gzvFAzBb #manufacturing #australianmanufacturing #quantumcomputing #diamonds #syntheticdiamonds
