Etched announced on Tuesday that it has closed a $700 million funding round led by Jane Street, following tests and a purchase of the startup’s AI hardware by the quant firm. The new financing values Etched at $21 billion.
The valuation increase is exceptionally rapid even by AI-industry standards: Etched was valued at $5 billion in December, then raised $300 million in a Series C at a $10.3 billion valuation in July. Now, within about a month, investors have nearly doubled the valuation again, adding roughly $11 billion.
What investors cite as the reason
Etched delivers full systems it calls “frontier inference clusters” (Nvidia uses the term AI factories for comparable full-stack systems). Co-founder and COO Robert Wachen told TechCrunch that investor enthusiasm centers on two components Etched designed from scratch to accelerate inference — the computation that follows a user prompt.
Wachen explained that inference has two stages: prefill and decode. The mathematically and compute-intensive prefill phase requires the system to understand the prompt and its context; the memory-intensive decode phase generates the output tokens that become the user-facing answer.
Etched built a prefill chip that runs at low voltage, which lets the company pack more transistors in without the heat problems typical of other high-end AI chips. That enables processing more tokens faster. For the decode phase, Etched developed a new type of memory and an interconnect it calls cluster-scale memory, which allows many chips to connect and share a memory pool with very low latency.
According to Wachen, the combined approach delivers higher speeds and lower costs.
Earlier perceptions and current capability
In Etched’s early days there was a perception that the company etched a specific model into its chips, meaning each chip would be customized to run one frontier model. That was the original intention, but it is no longer the case: Etched’s systems can run any frontier model.
In a blog post announcing the round, Jane Street said: “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. We’re excited to now have our own rack running in our datacenter.”
Investors involved
Besides Jane Street, Etched’s investors include Kleiner Perkins, Sequoia Capital, Andreessen Horowitz, Peter Thiel, Tiger Global, Bain Capital Ventures, Neo, Stripes, Primary, Positive Sum, Diffusion, Argo, and Blackstone.
The deal highlights rapid growth in Etched’s valuation and investor confidence as the company focuses on hardware innovations aimed at improving inference efficiency.
