Frore Systems Becomes a $1.64B Unicorn as the “Thermal Stack” Emerges as Foundational Infrastructure for the AI Era

Frore Systems, bringing a revolution in cooling technology for high-performance applications, led by Dr. Seshu Madhavapeddy, Dr. Surya P. Ganti, and the team, has announced the close of a $143 million Series D financing round, bringing total capital raised to $340 million and valuing the company at $1.64 billion. The Series D round was led by MVP Ventures and included participation from investors Fidelity Management & Research Company, Top Tier, Mayfield Fund, Clear Ventures, Addition, Qualcomm Ventures, StepStone Group, and Alumni Ventures.

AI compute demand and data-center capacity are projected to grow more than 3x by 2030, making heat a key constraint on performance.

The AI Thermal Stack, an integrated cooling architecture, manages heat extraction from hardware and its rejection into the atmosphere across data centers and edge platforms. As AI scales, it has become a critical infrastructure layer shaping compute density, energy efficiency, and performance.

Frore Systems is redefining the thermal stack across AI platforms:

-> AI Data Centers – Higher compute density with reduced weight and improved power and water efficiency.

-> Industrial Edge AI Gateways – Reliable performance for intensive AI workloads in compact, rugged, dustproof, and water-resistant systems.

-> Consumer AI Devices – High-performance AI computing in ultra-thin, silent form factors.

LiquidJet, a 3D short-loop jetchannel multi-stage direct liquid cooling (DLC) cold plate, delivers:

75% higher heat transfer efficiency

GPUs operating 8°C cooler

4% higher AI tokens per second

10% reduction in PUE

55% reduction in cold plate weight

Seamless drop-in integration within existing AI data center architectures

LiquidJet Nexus, a lightweight integrated cold plate system designed for NVIDIA Kyber ½U compute tray, integrates multiple LiquidJet units and delivers:

2× compute density per rack

65% reduction in thermal stack weight

Elimination of connectors, hoses, and manifolds within the compute tray

Support for inlet temperatures up to 53°C, removing the need for mechanical chillers

AirJet®, the world’s first solid-state active air-cooling chip, enables high AI performance in ultra-thin, silent, dustproof, and water-resistant devices, preventing thermal throttling in next-generation industrial edge gateways and consumer AI systems.

“AI infrastructure is undergoing a fundamental shift, with thermal performance emerging as a critical driver of compute performance and operating efficiency,” said Navin Chaddha, Managing Partner at Mayfield. “Frore Systems is reimagining the thermal stack through its 3D short-loop jetchannel cold plate and scalable manufacturing approach, unlocking the performance and efficiency required for next-generation AI platforms.”

“Rapid AI infrastructure expansion is placing new demands across every layer of the stack, with thermal architecture becoming increasingly central,” said Andre de Baubigny, Managing Partner at MVP Ventures. “Frore’s breakthrough platform enables higher compute density and efficiency across both hyperscale data centers and edge environments. Thermal innovation is expected to become a foundational layer of AI infrastructure, reinforcing continued support for the company’s global scaling.”

“Cooling has become the primary constraint on AI performance,” said Seshu Madhavapeddy, Founder and CEO of Frore Systems. “Conventional thermal technologies are unable to keep pace with the AI revolution. Frore’s advanced cooling platforms remove this barrier, unlocking AI performance from cloud to edge, supported by strong investor confidence amid global expansion.”
