Frore Systems announced it has raised $143 million in a Series D funding round, bringing the company’s total capital raised to $340 million and valuing the advanced thermal technology company at $1.64 billion. The funding will help accelerate global deployment of its cooling platforms across data centers and edge computing environments as demand for AI infrastructure continues to surge.
The Series D round was led by MVP Ventures and included participation from Fidelity Management & Research Company, Top Tier, Mayfield Fund, Clear Ventures, Addition, Qualcomm Ventures, StepStone Group, and Alumni Ventures.
Frore Systems said the investment will support scaling its thermal solutions, including LiquidJet, LiquidJet Nexus, and AirJet, which are designed to address the rapidly growing heat challenges associated with AI compute workloads. As AI models grow more complex and computing density increases, heat management has become a key bottleneck limiting system performance and efficiency.
The company describes the “AI Thermal Stack” as an integrated cooling architecture that extracts heat from AI computing and networking hardware and transfers it to the surrounding environment. This infrastructure layer spans both hyperscale data centers and edge platforms, and Frore argues it is becoming foundational to enabling higher compute density, improved energy efficiency, and sustained performance as AI workloads expand.
Frore’s LiquidJet technology is a 3D, short-loop, jet-channel, multi-stage direct liquid-cooling coldplate designed for AI data centers. According to the company, the platform enables 75% higher heat transfer efficiency, allows GPUs to operate about 8°C cooler, increases AI token generation throughput by about 4%, reduces power usage effectiveness by around 10%, and cuts coldplate weight by approximately 55%. The system is designed to function as a drop-in upgrade within existing AI data center architectures.
The company also introduced LiquidJet Nexus, an integrated coldplate system designed for NVIDIA Kyber half-U compute trays. LiquidJet Nexus integrates multiple LiquidJet units into a single lightweight architecture, enabling up to twice the compute density per rack while reducing the weight of the thermal stack by roughly 65%. The system eliminates the need for connectors, hoses, and manifolds and supports inlet temperatures up to 53°C, potentially eliminating the need for mechanical chillers in certain deployments.
Beyond data centers, Frore is targeting edge and consumer AI devices with its AirJet technology, a solid-state active air-cooling chip designed to deliver high-performance cooling in ultra-thin devices. The company says AirJet allows industrial edge AI gateways and consumer electronics to sustain higher compute performance while remaining silent, dustproof, and water-resistant, helping prevent thermal throttling in compact systems.
Frore Systems is headquartered in Silicon Valley and operates manufacturing in Taiwan. Its patented cooling technologies are already integrated into products from several major OEMs and system builders worldwide.
KEY QUOTES
“Cooling has become the single greatest limiter of AI performance. Traditional thermal technologies cannot keep pace with the AI revolution. Frore’s advanced cooling platforms remove that barrier — unleashing AI performance from Cloud to Edge. We are thrilled by the continued confidence of our investors as we scale to meet global demand.”
Dr. Seshu Madhavapeddy, Founder And CEO, Frore Systems
“We’re witnessing a fundamental shift in AI infrastructure, where thermal performance is critical for compute performance and reducing operating costs. What excites us is how Frore Systems is reimagining the Thermal Stack by building a 3D short-loop jetchannel coldplate and applying scalable manufacturing to cooling, unlocking the performance and efficiency required for the next generation of AI platforms.”
Navin Chaddha, Managing Partner, Mayfield
“AI infrastructure is being built at a pace and scale that is putting new demands on every layer of the stack, and thermal architecture is quickly becoming one of the most important. Frore has built a breakthrough platform that unlocks higher compute density and efficiency across both hyperscale data centers and edge environments. We believe thermal innovation will be a foundational layer of the AI infrastructure buildout, which is why we’re excited to continue backing Seshu and the Frore team as they scale globally.”
