Silicon Valley startup Frore Systems has raised $143 million in Series D financing, pushing its valuation to $1.64 billion and earning the company unicorn status. The round, announced Monday, was led by MVP Ventures with participation from Fidelity Management & Research Company, Qualcomm Ventures, Mayfield Fund, Top Tier, Clear Ventures, Addition, StepStone Group, and Alumni Ventures.
The funding brings Frore’s total capital raised to $340 million since the company was founded in 2018. Frore develops advanced thermal cooling technology for AI chips, a market segment that has become increasingly critical as artificial intelligence workloads push hardware to its thermal limits.
Why AI Cooling Has Become a Billion Dollar Problem
“Cooling has become the single greatest limiter of AI performance,” said Dr. Seshu Madhavapeddy, Frore’s co-founder and CEO. “Traditional thermal technologies cannot keep pace with the AI revolution.” The company, headquartered in San Jose with manufacturing operations in Taiwan, has built a product lineup that spans both massive data centers and compact edge devices.
Frore’s flagship data center product, LiquidJet, is a multi-stage liquid cooling coldplate that the company says delivers 75% higher heat transfer efficiency than conventional solutions. According to Frore, GPUs cooled with LiquidJet run 8 degrees Celsius cooler and produce 4% more AI tokens per second. A newer product, LiquidJet Nexus, integrates directly with NVIDIA’s Kyber compute trays and enables double the compute density per rack while eliminating the need for mechanical chillers.
On the consumer and edge side, Frore’s AirJet is a solid-state cooling chip that replaces traditional fans in ultra-thin laptops, edge AI devices, and industrial IoT systems using micro-electro-mechanical systems (MEMS) technology.
The Growing Demand for Thermal Infrastructure
The investment comes at a time when global AI compute demand and data center capacity are projected to grow threefold by 2030, according to industry estimates. As companies like NVIDIA, AMD, and Intel push chip performance higher, the heat generated by these processors has become a serious bottleneck. Data centers already consume enormous amounts of energy just for cooling, and the problem is expected to worsen as AI infrastructure spending accelerates across the industry.
“Frore has built a breakthrough platform that unlocks higher compute density and efficiency across both hyperscale data centers and edge environments,” said Andre de Baubigny, Managing Partner at lead investor MVP Ventures.
What the Funding Means for the AI Supply Chain
Frore plans to use the capital to accelerate the global scale-up of its thermal platforms across data center and edge markets. The company’s products are already integrated into systems from major OEMs and system builders worldwide, though Frore has not disclosed specific customer names.
The Series D follows an $80 million Series C round in 2024. With thermal management now emerging as a foundational layer of AI infrastructure alongside chips, networking, and power delivery, Frore’s rapid ascent to unicorn status signals that investors are betting big on the companies solving the physical constraints of the AI boom.
Navin Chaddha, Managing Partner at Mayfield, one of the returning investors, said Frore is “reimagining the Thermal Stack by building a 3D short-loop jetchannel coldplate and applying scalable manufacturing to cooling.” The company’s approach treats heat management not as an afterthought but as a core infrastructure challenge that determines how fast and how far AI can scale.
