Etched AI Chip Startup Hits $10.3B Valuation, Doubles in 7 Months
Key Points
- Etched closed a $300 million Series C at $10.3 billion valuation, doubling its December valuation of $5 billion.
- The startup has booked $1 billion in orders and successfully manufactured its custom AI inference chips with TSMC.
- Sequoia-led round marks the highest valuation ever for a Sequoia Series C, with backing from Andreessen Horowitz, SK Hynix, and investor Andrej Karpathy.
For the prefill phase, which involves understanding prompts and processing context, Etched created a chip that operates at "dramatically" lower voltage than competing AI chips, according to Wachen. Lower voltage reduces heat generation and allows denser transistor packing. For the decode phase, which generates output tokens with less computation but high memory demands, Etched developed what it calls "cluster scale memory"—an interconnect technology enabling multiple chips to share memory at low latency.
The company was founded on the premise that transformer-based AI models required specialized silicon, a concept skeptics initially dismissed as unfeasible. However, the notion has gained credibility: Google is reportedly pursuing similar concepts with its Frozen v2 chip for Gemini. Etched's systems can run various model architectures including Mixture of Experts models like DeepSeek and Qwen, as well as non-transformer designs such as Mamba, contrary to early perceptions that the chips were locked to specific large language models.

Etched's three founders—CEO Gavin Uberti, Wachen, and CTO Chris Zhu—left Harvard to launch the company with minimal business experience. Wachen recalled arriving in the Bay Area after leaving school with no office or apartment arranged, sleeping on a friend's floor using a towel as a blanket. "We had no idea how hard it was going to be," he said, adding: "I think we still have to be humbled by what it will take to actually get to scale."
The rapid valuation increase within seven months reflects investor confidence despite limited public access to Etched's systems. The startup's success trajectory suggests that specialized inference chips may command significant investor appetite, particularly as companies seek cost-efficient alternatives to general-purpose AI accelerators for production workloads.

What This Means
Etched's path to mass production and scale will determine whether the $10.3 billion valuation holds. With $1 billion in preorders and support from major chip manufacturers like SK Hynix, the startup appears positioned to capture inference-focused customers. However, production challenges and competition from Nvidia's expanding chip portfolio could constrain growth.
