Frore Systems hits $1.64B valuation after $143M funding to cool AI chips as AI data centers overheat

The AI boom has created a quiet crisis inside data centers. Chips are getting faster, racks are getting denser, and heat is piling up. Cooling, once treated as background plumbing, is now one of the biggest limits on how much AI compute can actually run.

That reality is turning thermal technology into a new battleground for infrastructure startups.

Silicon Valley–based Frore Systems announced today it has reached unicorn status after closing a $143 million Series D round, bringing its total funding to $340 million and valuing the company at $1.64 billion. The company develops cooling systems built for modern AI hardware and plans to use the capital to scale production and expand deployments across data centers and edge computing systems.

Fidelity-Backed AI Chip Cooling Startup Frore Valued at $1.64 Billion in New Funding

The round was led by MVP Ventures with participation from Fidelity Management & Research Company, Top Tier, Mayfield Fund, Clear Ventures, Addition, Qualcomm Ventures, StepStone Group, and Alumni Ventures.

Bloomberg confirmed the financing, reporting, “Frore Systems Inc., which makes liquid cooling technology for AI chips, raised $143 million in a funding deal that values the startup at $1.64 billion. The round was led by MVP Ventures and includes investments from Fidelity Management & Research Co., Top Tier, Mayfield Fund, and Qualcomm Ventures. The company plans to use the funding to expand its manufacturing operations.”

The growing heat problem inside AI infrastructure

The surge in AI workloads is pushing physical limits inside data centers. GPUs built for training large models consume massive amounts of energy and release significant heat. Industry forecasts suggest global AI compute demand and data-center capacity could grow more than threefold by 2030, pushing cooling systems into the spotlight.

What engineers often call the “AI thermal stack” is becoming a major part of infrastructure planning. That stack includes every step required to remove heat from processors and expel it from buildings. Cooling performance now affects how many chips can fit inside a rack, how much electricity a facility consumes, and how reliably AI workloads run.

Frore Systems is betting that thermal engineering will shape the next generation of computing platforms.

The company builds cooling technologies that target three main environments: hyperscale AI data centers, industrial edge systems running heavy inference workloads, and consumer devices packed with on-device AI.

LiquidJet targets the heart of AI data centers

One of Frore’s main products, LiquidJet, uses a multi-stage liquid cooling approach that sits directly on top of processors. The system pushes coolant through small channels positioned above the chip surface. The design removes heat faster than conventional cold plates and fits into existing server designs.

Frore says LiquidJet allows GPUs to operate several degrees cooler and increases compute throughput during AI workloads. The company reports higher heat-transfer efficiency, lower infrastructure weight, and reduced power consumption.

A second platform, LiquidJet Nexus, integrates multiple cooling units into a single lightweight system built for next-generation compute trays. Frore says the design can double compute density per rack and support warmer inlet temperatures, removing the need for mechanical chillers in some deployments.

For operators building hyperscale clusters, shaving weight, power, and plumbing complexity can translate into major operational savings.

Cooling moves beyond the data center

The company’s technology isn’t limited to server rooms. Frore’s AirJet chip targets compact electronics running AI models locally.

AirJet is a solid-state cooling module designed for thin laptops, edge gateways, and other small devices where airflow and fan noise create engineering trade-offs. The module helps prevent processors from slowing down when temperatures rise.

That capability has become more relevant as AI features spread into everyday hardware.

“We’re witnessing a fundamental shift in AI infrastructure, where thermal performance is critical for compute performance and reducing operating costs,” said Navin Chaddha, Managing Partner at Mayfield. “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.”

Investors see thermal engineering as a structural part of the AI infrastructure build-out.

“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,” said Andre de Baubigny, Managing Partner at MVP Ventures. “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.”

Heat may define the next phase of AI computing

Frore founder and CEO Dr. Seshu Madhavapeddy argues that cooling has become one of the largest barriers to AI performance.

“Cooling has become the single greatest limiter of AI performance,” he said. “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.”

Frore Systems says its cooling technologies already appear in hardware from major OEMs and system builders. The company operates out of Silicon Valley and runs manufacturing operations in Taiwan.

As AI infrastructure grows larger and more power-hungry, the competition around chips may soon be matched by another race happening just above them: the race to keep them cool.
