Frore Hits $1.64B Valuation on AI Chip Cooling Breakthrough
Frore Systems raised $143 million in a Series D funding round that values the Silicon Valley-based thermal technology company at $1.64 billion, the company disclosed on Sunday.
The Series D round backs the expansion of liquid and solid-state cooling platforms as heat management emerges as a key constraint on AI compute performance.
Frore Systems raised $143 million in a Series D funding round that values the Silicon Valley-based thermal technology company at $1.64 billion, the company disclosed on Sunday. The round brings the total capital raised to $340 million.
MVP Ventures led the round, with participation from Fidelity Management & Research Co., Top Tier, Mayfield Fund, Clear Ventures, Addition, Qualcomm Ventures, StepStone Group, and Alumni Ventures. Frore said it will use the capital to scale its manufacturing operations in Taiwan and expand its data center sales team in the United States.
The investment targets what Frore describes as the “AI Thermal Stack,” an integrated cooling architecture that extracts heat from AI computing and networking hardware. The company argues that as AI models grow more complex and chip power densities rise, thermal management has become a primary constraint on system performance, not processor speed or memory bandwidth.
“Cooling has become the single greatest limiter of AI performance.Traditional thermal technologies cannot keep pace with the AI revolution,” shared Seshu Madhavapeddy, Founder and CEO, Frore.

Frore’s flagship LiquidJet platform is a direct liquid-cooling coldplate designed for AI data centers. The company says it delivers 75% higher heat transfer efficiency than conventional systems, allows GPUs to run approximately 8 degrees Celsius cooler, and cuts coldplate weight by roughly 55%. The company also introduced LiquidJet Nexus, an integrated system built for NVIDIA Kyber half-U compute trays. It eliminates connectors, hoses, and manifolds and supports inlet temperatures up to 53 degrees Celsius, potentially removing the need for mechanical chillers in some deployments.
Separately, Frore markets AirJet, a solid-state active air-cooling chip targeting edge devices and consumer electronics. The company says AirJet allows compact systems to sustain higher compute performance while remaining silent and dustproof, a configuration designed to prevent thermal throttling in thin industrial and consumer AI hardware.
Frore has built a breakthrough platform that unlocks higher compute density and efficiency across both hyperscale data centers and edge environments.

The round places Frore among a small set of thermal infrastructure companies attracting institutional capital as hyperscalers accelerate AI buildout. The round comes amid escalating funding in AI thermal solutions. Accelsius raised $65M Series B in January 2026 for two-phase liquid cooling. Frore’s larger raise achieves $1.64B unicorn valuation, showing conviction in solid-state alternatives.
Frore is headquartered in San Jose and manufactures in Taiwan. Its cooling technologies are integrated into products from several major original equipment manufacturers, the company said, without naming them. Madhavapeddy previously co-founded Spatial Wireless, which was acquired by Alcatel-Lucent, and Sipera Systems, which was acquired by Avaya.
