Etched Doubles Valuation to $21B on AI Hardware Prowess

Etched has announced a significant funding round, securing $700 million and achieving a $21 billion valuation. This latest investment, spearheaded by Jane Street, represents a dramatic increase from its previous $5 billion valuation in December and $10.3 billion in July of last year. The company's rapid valuation growth highlights intense investor interest in its advanced AI technology.

Etched specializes in delivering AI as complete systems, termed 'frontier inference clusters.' Co-founder Robert Wachen explained that their proprietary technology focuses on optimizing the two stages of AI inference: prefill and decode. They have developed a new prefill chip designed for low-voltage operation, enabling higher transistor density and faster processing without excessive heat.

Furthermore, Etched has introduced 'cluster-scale memory' for the decode phase. This innovation allows multiple chips to interconnect seamlessly, sharing memory with low latency. The company asserts that this approach leads to enhanced speeds and cost efficiencies. Notably, Etched's systems are now versatile enough to run any frontier AI model, moving beyond earlier perceptions of hardware-specific model etching.
