Etched’s Valuation Soars to $21 Billion in Just One Month

Etched announced on Tuesday that it has successfully raised an additional $700 million, reaching a valuation of $21 billion. Jane Street led the funding round after the prominent quant fund assessed and acquired the startup’s AI hardware.

This remarkable rise in valuation has occurred rapidly, even by the standards of the AI sector. Just last December, Etched was valued at $5 billion and raised $300 million in a Series C round with a valuation of $10.3 billion in July. Investors have nearly doubled its worth to $21 billion, achieving an increase of nearly $11 billion in just one month.

Etched provides its AI technology through comprehensive systems known as “frontier inference clusters.” In contrast, competitor Nvidia describes its complete systems as AI factories.

Robert Wachen, co-founder and COO, told TechCrunch that the enthusiasm from investors is due to Etched’s development of two revolutionary components designed to enhance inference—the computational task that occurs after a user submits a prompt.

“Inference consists of two phases,” Wachen explained, “prefill and decode.” The mathematically demanding “prefill phase” involves the system grasping the prompt and its context. The following memory-intensive “decode” phase results in the system generating output tokens, which reflect the actual response provided to the user.

Etched has engineered a prefill chip that operates at low voltage, allowing the integration of a larger number of transistors without the usual overheating challenges associated with high-performance AI chips. This innovation facilitates faster processing of an increased number of tokens. Furthermore, Etched has created a novel type of memory and an interconnect for the decode phase, termed cluster-scale memory.

“This configuration enables multiple chips to connect and use a shared memory pool at exceptionally high speeds and with minimal latency,” Wachen revealed. Etched asserts that this setup will lead to improved speeds and lower costs.

The company is still addressing the initial misconceptions around its technology, which suggested it was designed to etch specific models onto its chips, implying each chip was tailored for one frontier model. While that was the initial vision, it is now outdated; Etched’s systems are capable of running any frontier model.

In the blog post announcing the new funding, investment firm Jane Street stated, “We tested the chip and are pleased with the initial results. Etched’s innovative approach to inference provides the precision required for our most demanding workloads. We’re excited to have our own rack functional in our datacenter.”

Additional prominent investors in Etched include Kleiner Perkins, Sequoia Capital, Andreessen Horowitz, Peter Thiel, Tiger Global, Bain Capital Ventures, Neo, Stripes, Primary, Positive Sum, Diffusion, Argo, and Blackstone.
