Syenta
Syenta is an Australian deep-tech semiconductor company building next-generation chip-to-chip interconnects for the AI era. Spun out of the Australian National University, it has developed a proprietary process called Localized Electrochemical Manufacturing (LEM) that deposits and patterns metal in a single step, producing micron-scale interconnects across large packages with fewer process steps. The technology targets the 'memory wall' that limits AI and high-performance computing, aiming to raise interconnect density and bandwidth while cutting manufacturing cost and waste. Headquartered in Sydney with a new development facility in Tempe, Arizona, Syenta has raised more than A$37 million, with former Intel CEO Pat Gelsinger joining its board.
HyperLight Corporation
HyperLight is a Cambridge, Massachusetts company that designs and manufactures photonic integrated circuits on thin-film lithium niobate (TFLN), a material prized for ultrafast, low-voltage electro-optic modulation. A 2018 spin-out from Marko Loncar's lab at Harvard, the company built what it describes as the industry's first high-volume, qualified 6-inch TFLN manufacturing line - now expanding to 8-inch - and packages it as a modular TFLN Chiplet platform. Its modulator chips target the bandwidth and power-efficiency demands of AI data centers, telecom optical networks and high-performance computing, enabling 1.6 Tbps-class links at CMOS-level drive voltages.
Zayo Group
Zayo Group is a Denver-based communications infrastructure company that owns and operates one of North America and Europe's largest fiber-optic networks - over 150,000 route miles after its 2026 acquisition of Crown Castle's fiber business. It sells the physical layer of the internet: dark fiber, wavelengths, Ethernet, IP transit, dedicated internet access, colocation and managed edge services to wireless carriers, hyperscalers, enterprises, governments and ISPs. Founded in 2007 on a contrarian bet that bandwidth demand would only explode, Zayo has spent its life buying and building fiber, and is now positioning that network as the backbone for AI workloads moving data between data centers.
