Frore Systems hit $1.64B unicorn on $143M Series D ($340M total) for its AirJet solid-state MEMS cooling chip that replaces fans in AI and consumer hardware.
Frore Systems is a semiconductor cooling company that has invented AirJet, the world's first solid-state active cooling chip for electronics. Founded in 2020 and headquartered in San Jose, California, Frore developed a fundamentally new approach to thermal management: silicon-based micro-electromechanical systems (MEMS) that move air through ultrasonic vibration with no moving mechanical parts. This technology directly addresses one of the most persistent constraints in AI hardware and consumer electronics—how to remove heat from increasingly dense chips without fans, noise, or mechanical failure points.\n\nFrore's AirJet chips integrate directly into the PCB or device chassis and can be tiled to scale cooling capacity for different thermal envelopes. The technology is applicable across a wide range—from thin laptops and tablets that currently rely on passive cooling to edge AI inference hardware, autonomous vehicles, and data center accelerators. NVIDIA CEO Jensen Huang publicly encouraged Frore to expand into data center applications, a significant market signal. Frore's solid-state approach also offers advantages in reliability, acoustic performance, and form factor that conventional fan-based cooling cannot match.\n\nIn March 2026, Frore Systems closed a $143M Series D, bringing its total funding to $340M and pushing its valuation to $1.64B—joining the unicorn club. The round reflects growing investor confidence that thermal management will be a critical bottleneck as AI chip power densities continue to rise. With Jensen Huang's endorsement and a clear path into data center cooling, Frore is positioned to become a key infrastructure supplier for the next generation of AI hardware deployments.
Global payments infrastructure founded by Patrick and John Collison (YC W10); $1.4T payments volume in 2024; $18B+ revenue; $106.7B valuation as of Sept 2025; powers everything from startups to Fortune 500 companies with developer-first API design.
Stripe is a global payments infrastructure company founded in 2010 by Irish brothers Patrick and John Collison, headquartered in San Francisco, California and Dublin, Ireland. Stripe was born from the insight that accepting payments online was unnecessarily complex for developers, and that a well-designed API could unlock an entire generation of internet businesses. The company went through Y Combinator's Winter 2010 batch and grew to become the defining payments infrastructure layer of the modern internet economy, processing payments for businesses in virtually every industry worldwide.\n\nStripe's platform provides payment processing, fraud prevention via Stripe Radar, subscription billing, revenue recognition, banking-as-a-service through Stripe Treasury, corporate card issuance, identity verification, and tax compliance tools. It serves a spectrum from early-stage startups to publicly traded enterprises including Amazon, Google, Salesforce, and Shopify. Stripe's developer-first philosophy — comprehensive documentation, SDKs in every major language, and a sandbox testing environment — created an ecosystem of millions of businesses built entirely on its infrastructure.\n\nStripe processed $1.4 trillion in total payment volume in 2024 and generates over $18 billion in annual revenue, with a valuation of $106.7 billion as of September 2025. The company has remained private longer than most comparably sized technology companies, giving it flexibility to invest in long-term product expansion. An April 2024 partnership with Apple Pay extended Stripe's reach further into mobile and in-store commerce. Stripe competes with Adyen, Braintree (PayPal), and Square, but its developer ecosystem depth and global infrastructure make it the default payments platform for a generation of technology companies.
