With AI pushing infrastructure to its limits, global tech giants are betting that Teramount’s optical connectivity platform will become the backbone of next-generation data centers.
As hyperscalers step up spending, investors are now placing strategic bets on the less-visible layers of AI infrastructure – like optical connectivity. In a $50 million Series A round announced this week, Israeli startup Teramount captured the attention of industry heavyweights including AMD Ventures, Samsung Catalyst Fund, Hitachi Ventures, Wistron, and lead investor Koch Disruptive Technologies, alongside existing backer Grove Ventures.
This comes at a pivotal moment in the industry: Alphabet (Google’s parent company) recently increased its 2025 capital expenditure forecast by $10 billion, pushing total capex to $85 billion, driven by surging demand for AI-powered cloud services and data center infrastructure. Its cloud division grew by 32% year-over-year to $13.6 billion, while its overall revenue hit $96.4 billion in Q2 2025 – highlighting the scale and urgency fueling investments across hardware and networks.
Against this backdrop of record-setting AI infrastructure budgeting, Teramount is advancing a foundational layer of the hardware stack: fast, reliable, and scalable connectivity. Rather than competing in chip design, the Jerusalem-based company focuses on a critical bottleneck in AI systems – efficiently transmitting data between processors – using optical fiber instead of traditional copper wiring.
At the heart of its offering is the TeraVerse™ platform, featuring self-aligning passive connectors that link fiber-optic cables to silicon photonics chips within Co-Packaged Optics (CPO) systems. Teramount’s PhotonicPlug™ and PhotonicBump™ technologies enable high-precision fiber-to-chip alignment using standard semiconductor process flows – removing the need for time-intensive, expensive manual alignment.
“This investment, which brings together strong financial and strategic investors representing important parts of the optical connectivity ecosystem, is a testament to the potential of our technology in AI infrastructure and other high-performance applications,” said Teramount co-founder and CEO Dr. Hesham Taha.
Notably, AMD’s participation signals that even chipmakers now view optical interconnect technologies as part of their competitive architecture strategy – not just hardware suppliers. Meanwhile, Samsung Catalyst Fund and Hitachi Ventures bring deep domain experience in photonics and semiconductors, and KDT backing underscores confidence that Teramount’s platform may become a critical building block in next-gen cloud and AI architectures.
Teramount’s traction is further underscored by partnerships with major foundries and assembly partners, including Tower Semiconductor and GlobalFoundries, positioning the company well for high-volume industrial deployment at scale.
For the market, Teramount’s funding round may highlight a broader shift: moving beyond just compute-centric plays (GPUs, AI chips) to invest in the “plumbing” of AI infrastructure – connectivity, packaging, interconnects, and fabrication enablers. As hyperscalers such as Google, Microsoft, Meta, and Amazon collectively plan to spend hundreds of billions in capex through 2025–2026, firms tackling the physical limits of data movement may emerge as hidden leverage points within the AI ecosystem.
With capital now secured and strategic alignment in place, Teramount’s next phase involves scaling manufacturing capabilities and expanding its engineering team – just as demand for optical-native infrastructure ramps up across enterprise and hyperscale deployments.
