AI Chip Startup Etched Raises $300M Series C at $10.3B Valuation

Funding and Valuation Growth

Etched, an AI chip startup established in 2022, has completed a $300 million Series C funding round. This investment places the company's valuation at $10.3 billion. The round was led by Sequoia, with additional participation from Andreessen Horowitz, SK Hynix, Jane Street, and Diffusion Capital.

Rapid Valuation Increase

This latest funding round marks a significant increase in Etched's valuation, which was $5 billion just seven months prior in December. The company states this is the highest valuation ever for a Sequoia-led Series C round. Etched previously announced the successful manufacturing of its chips, client testing of its first full systems, and $1 billion in booked orders.

Addressing AI Inference Challenges

Etched's core offering involves chips and full systems designed to accelerate AI model inference, the computational process that occurs after a user submits a prompt. The company developed two new components from scratch to improve inference speed. These systems are capable of running various AI models, including Mixture of Experts models and non-transformer designs like Mamba, contrary to perceptions that they are limited to specific large language models (LLMs).

Specialized Chip Design

The inference process is divided into two stages: prefill and decode. The prefill phase, which involves understanding the prompt and context, is mathematically and compute-intensive. The decode phase generates output tokens and requires substantial memory. Etched created a prefill chip designed to operate faster, addressing the computational demands of this initial stage.
