Frore Systems Raises $143M for AI Chip Cooling

Eight years ago, two former Qualcomm engineers started a company to cool laptops without fans. Now they're a unicorn. Frore Systems just closed a $143 million Series D at a $1.64 billion valuation, cementing its status as one of the most improbable deep-tech success stories in the AI infrastructure boom. The pivot that got them here? A single demo that caught Jensen Huang's attention.

From Silent Laptops to Screaming GPUs

Frore Systems was founded in 2018 by Seshu Madhavapeddy and Surya P. Ganti, both Qualcomm veterans. Madhavapeddy had been VP/GM of Qualcomm's in-display fingerprint sensor business — the kind of guy who thinks in silicon and thermal envelopes. Their original product, AirJet, was a solid-state active air-cooling chip designed to replace noisy fans in ultra-thin laptops and edge devices. Clever engineering. Niche market.

Then, roughly two years ago, Nvidia CEO Jensen Huang saw a demo of the AirJet technology. His reaction wasn't just polite interest — he suggested Frore build liquid-cooling solutions for AI chips and systems. When the man shipping the hottest silicon on the planet tells you to solve his heat problem, you listen.

Frore listened. And pivoted hard.

The result is LiquidJet, a direct-to-chip liquid cooling platform that the company claims delivers 75% higher heat transfer efficiency than conventional solutions, runs GPUs 8°C cooler, and cuts Power Usage Effectiveness (PUE) by 10%. There's also LiquidJet Nexus, designed specifically for compute trays to increase density and reduce weight. These aren't incremental improvements — they're the kind of thermal gains that let data center operators squeeze more AI workloads into the same rack space without melting everything.

The Money and Who's Writing the Checks

The $143 million Series D was led by MVP Ventures, with participation from Fidelity Management & Research Co., Top Tier, Mayfield Fund, Clear Ventures, Addition, Qualcomm Ventures, StepStone Group, and Alumni Ventures. Total funding now sits at $340 million.

The investor list tells a story. Fidelity brings late-stage institutional credibility. Qualcomm Ventures signals that Frore's tech works across chip architectures, not just Nvidia's. Mayfield has been in since earlier rounds, doubling down. This isn't speculative money chasing a hot sector — it's a mix of strategic and financial investors betting that thermal management is becoming foundational infrastructure for AI.

And that bet makes sense. Here's why.

Heat Is the New Bottleneck

Every conversation about AI infrastructure eventually hits the same wall: power and cooling. You can build the most advanced GPU cluster on the planet, but if you can't dissipate the heat, you're throttling performance or burning money on oversized cooling systems. As AI models scale and chip power draws climb past 1,000 watts per GPU, traditional air cooling simply cannot keep up.

The numbers back this up. Direct-to-chip cooling startups raised $74 million in equity funding across 2025 — a 208% jump from 2024. Data-center capacity requirements are projected to more than triple by 2030. And in Q1 2026 alone, AI infrastructure startups have collectively raised a staggering $68.9 billion across 620 rounds, according to Fundz data. The thermal layer is no longer an afterthought — it's a prerequisite.

"The thermal stack is emerging as foundational infrastructure for the AI era."

Frore's framing is aggressive but accurate. If you can't cool it, you can't compute it.

Why Frore Stands Out

The AI cooling space isn't empty. Vertiv, CoolIT, and other incumbents have liquid cooling products in production data centers today. So what makes a startup worth $1.64 billion?

Three things:

• Chip-level engineering DNA. Madhavapeddy and Ganti come from semiconductor design, not HVAC. Their approach treats cooling as a silicon problem, not a plumbing problem. AirJet was literally a MEMS chip. LiquidJet carries that same micro-scale precision into liquid cooling.
• Cross-platform compatibility. Frore's solutions work with Nvidia, AMD, and Qualcomm chips. In a market where hyperscalers are increasingly diversifying their silicon suppliers, vendor-agnostic cooling is a strategic advantage.
• Full-stack thermal platform. From edge devices (AirJet) to data center racks (LiquidJet) to high-density compute trays (LiquidJet Nexus), Frore covers the entire AI compute spectrum. That breadth is rare.

The Jensen Huang connection doesn't hurt either. When Bloomberg reported on the raise, the Nvidia CEO's role in inspiring the pivot was front and center. In a market where Nvidia's roadmap dictates infrastructure spending, having that implicit endorsement carries enormous weight with buyers and investors alike.

The Risks

Let's not pretend this is a sure thing. Frore is manufacturing physical hardware at scale — that's fundamentally harder and more capital-intensive than shipping software. The $143 million will go toward expanding manufacturing operations, and execution risk is real. Incumbents like Vertiv have existing customer relationships, field service teams, and production lines that a startup can't replicate overnight.

There's also the Nvidia Vera Rubin wildcard. When Nvidia announced its next-gen chips in January 2026 with potentially improved power efficiency, cooling stocks briefly tanked. If future chip architectures dramatically reduce thermal output, the urgency around advanced cooling solutions could soften. That said, every generation of chips has promised better efficiency — and every generation has also cranked up total power to run bigger models. The trend line favors Frore.

The Bottom Line

Frore Systems is a deeply technical company that caught the right wave at the right time — and had the right person notice. The pivot from silent laptop chips to data center liquid cooling is the kind of strategic leap that either kills a startup or makes it. At $1.64 billion, the market is betting on the latter.

AI infrastructure spending shows zero signs of slowing down. Heat isn't going away. If anything, it's getting worse as models scale and inference workloads explode. Frore is positioning itself not as a cooling vendor, but as a thermal infrastructure layer — as essential to AI compute as networking or storage. That's a bold claim. But with $340 million in the bank, Fidelity on the cap table, and Jensen Huang's implicit blessing, they've earned the right to make it.
