Etched.ai

What Etched.ai does

Etched.ai (DBA: Etched) is an AI semiconductor startup developing Sohu, claimed to be the world's first transformer-specific ASIC, designed exclusively to accelerate transformer model inference. The company's core thesis is that general-purpose GPUs like the Nvidia H100 are suboptimal for transformer workloads, and that a purpose-built ASIC can deliver an order-of-magnitude improvement in tokens per dollar and per watt for dense models, sparse mixture-of-experts architectures, and diffusion models. Etched is headquartered in San Jose, California, was founded in 2024 by Harvard dropouts Gavin Uberti (CEO), Chris Zhu (Co-Founder/Thiel Fellow), and Robert Wachen (President), and has assembled a leadership bench drawn from NVIDIA, Google DeepMind, Broadcom, Intel, and Cypress.

The company sells or plans to sell Sohu as a rack-scale AI inference system through a direct B2B enterprise sales motion targeting AI companies, hyperscalers, and cloud providers running transformer-based LLMs and generative AI workloads. Manufacturing is handled in partnership with TSMC, with HBM memory sourced from SK Hynix, Samsung, and Micron; chip design completion, manufacturing, and shipping are targeted for 2027. The company also partnered with Decart to launch Oasis, a real-time AI video generation demonstration intended to showcase Sohu's transformer inference throughput.

Etched is a venture-backed private company that has raised approximately $625M across a Series A ($120M, June 2024, led by Positive Sum and Primary Venture Partners) and a Series B ($500M, January 2026, led by Stripes) at a $5B post-money valuation, with additional participation from Peter Thiel, Stanley Druckenmiller, Ribbit Capital, Jane Street, Marvell, Spark Capital, and others. The company does not currently disclose revenue, consistent with its pre-shipment status.

Core offering

Etched.ai designs and sells the Sohu chip, the world's first transformer-specialized ASIC, purpose-built to accelerate AI inference for transformer-based models such as large language models, sparse Mixture-of-Experts, and diffusion models. The company also delivers a rack-scale AI inference system that combines the Sohu ASIC with high-bandwidth memory and partners with TSMC for chip fabrication.

Product overview

Etched.ai is a semiconductor startup developing specialized ASIC chips optimized exclusively for transformer model inference. The company's primary product is the Sohu chip - a purpose-built transformer ASIC that competes with Nvidia's general-purpose GPUs in the AI accelerator market. Sohu is designed to provide superior performance and energy efficiency for transformer-based AI workloads including large language models (LLMs), sparse mixture-of-experts architectures, and diffusion models. The company partners with TSMC for chip manufacturing and has raised significant funding ($120M Series A in June 2024, $500M Series B in early 2026) to support chip design completion with manufacturing and shipping targeted for 2027.

Products and services

• Sohu Sohu is a transformer-specialized ASIC chip built by Etched.ai to run transformer-based AI models (LLMs, sparse MoEs, diffusion) with significantly higher tokens per dollar and per watt compared to general-purpose GPUs. It is sold to AI companies, hyperscalers, and cloud providers requiring efficient inference compute.
• Oasis Oasis is the first experiential real-time open-world AI model that generates interactive video entirely through AI, enabling users to move, jump, pick up items, and interact with a physics-based environment. It is powered by transformer-based AI inference that Etched's Sohu chip is designed to accelerate.

Broad incumbents

• Google (TPU): Google's TPU is a vertically integrated AI accelerator optimized for transformer workloads and the closest analog to Etched's transformer-specialized ASIC. It is a major internal alternative for hyperscaler-class AI customers and sets the architectural benchmark for the category.
• Nvidia: Nvidia is the dominant incumbent in AI accelerators with its H100/H200/Blackwell GPUs and CUDA software stack. It is Etched's primary direct competitor in AI inference compute, and the standard against which Etched's 10-20x performance claims are benchmarked.

Direct peers

• Cerebras Systems: Cerebras builds wafer-scale AI accelerators (WSE) targeting both training and inference workloads for hyperscalers and enterprises. It competes head-to-head with Etched in selling dedicated AI silicon to large AI customers, though Cerebras's chip is general-purpose rather than transformer-specific.
• Groq: Groq develops LPU (Language Processing Unit) inference accelerators optimized for low-latency LLM serving. It directly targets the same transformer inference use case as Etched's Sohu and competes for similar hyperscaler and AI-company design wins.
• SambaNova Systems: SambaNova builds RDU (Reconfigurable Dataflow Unit) AI accelerators aimed at enterprise and government AI training and inference deployments. It is a comparable fabless AI chip startup targeting transformer-class workloads with similar enterprise go-to-market motion.
• Tenstorrent: Tenstorrent designs RISC-V based AI accelerators for training and inference, led by Jim Keller. Like Etched, it is a well-funded fabless AI chip startup competing for design wins in hyperscaler and enterprise AI infrastructure.
• Graphcore: Graphcore (now part of SoftBank) developed IPU (Intelligence Processing Unit) accelerators for AI workloads. It is a comparable specialized AI silicon company targeting transformer and ML inference, though it has shifted focus following acquisition.

Emerging players

• Lightmatter: Lightmatter builds photonic AI accelerators and interconnect products for data center AI workloads. It targets adjacent compute-infrastructure opportunities for AI inference and is a comparable well-funded AI hardware startup.
• Mythic AI: Mythic develops analog compute-in-memory AI inference chips for edge and data center deployments. It overlaps with Etched in the AI inference accelerator category, though its analog approach targets a different power/performance envelope.
• Hailo: Hailo builds edge AI inference processors for automotive and industrial use cases. While primarily edge-focused rather than data center, it represents an adjacent fabless AI accelerator company targeting transformer and CNN workloads with similar hardware specialization philosophy.
