Etched raised $700 million at a $21 billion valuation, doubling its post-money mark 26 days after closing a $300 million Series C at $10.3 billion on July 23. The round was led by Jane Street, which also happens to be the San Jose startup’s first paying customer and took delivery of an Etched rack last month.
That sequencing is the story. The quant firm didn’t just anchor a term sheet; it received hardware, ran the workloads, and then wrote the check to lead the next round. “We tested the chip and are pleased with the early results. Etched’s unique approach to inference delivers the precision we will need to support our most demanding workloads,” Jane Street said in a statement accompanying the announcement. In a market where GPU purchase orders often precede any actual silicon by a year or more, a customer-led round after real delivery is a different kind of signal.
The numbers frame the velocity. Etched was valued at $5 billion in December, meaning the company has roughly quadrupled in eight months and now sits above the $20 billion Nvidia paid the same month to license Groq’s technology and hire its leadership. Total capital raised to date runs to $1.9 billion, against more than $1 billion in signed customer contracts. Kleiner Perkins, Sequoia, Andreessen Horowitz, Tiger Global, Bain Capital Ventures, Neo, Primary, Stripes, Positive Sum, and Blackstone joined the round, alongside existing quant investors Hudson River Trading, Jump Trading, and Two Sigma.
CEO Gavin Uberti, one of three Harvard dropouts who founded the company, took three years to ship the first rack. The engineering claims are specific: 44 days from receiving test chips off TSMC’s N4P process to running inference workloads, and a proprietary interconnect that completes some communications tasks in 700 milliseconds versus 4,000 on rival chips. Internally developed components called Low Voltage Inference and Cluster Scale Memory sit underneath. The racks run DeepSeek, Qwen, and the non-transformer Mamba architecture, which matters because Etched’s original bet on transformer-specialized silicon has quietly widened.
The talent geometry is worth noting. Roughly 15% of Etched’s approximately 400 employees came from Nvidia, and Jimmy Daley, who ran data-center systems engineering at Nvidia until retiring in July, is now an investor. Nvidia’s Groq acquisition wasn’t just a product move; it was a signal that the incumbent views bespoke inference silicon as strategically threatening enough to buy the org chart. The market is now pricing a competitor above that acquisition, funded partly by the ex-Nvidia executive who used to build the thing being competed with.
Inference economics have become the axis on which the next phase of the AI buildout turns. Etched has priced accordingly.
