Etched raises $700M at $21B valuation, Jane Street leads and becomes first customer
Etched, an AI inference chip startup, announced on August 18-19 a $700M Series D at a $21B post-money valuation, led by quant trading giant Jane Street with Kleiner Perkins, Sequoia, A16Z, Peter Thiel, BCV and Blackstone participating. Alongside the round, Jane Street also became the company's first customer, with the first Sohu-based inference system delivered and shipped. Per @Pablomiller, Etched was valued at $10.3B in July — doubling in under a month.
Confirmed
- Etched raised $700M in Series D at a $21B post-money valuation (some reposts said $21.5B; the official figure is $21B)
- Investors include Jane Street, Kleiner Perkins, Sequoia, A16Z, Peter Thiel, BCV and Blackstone
- Jane Street is both lead investor and first customer; the first rack / first Sohu inference system has been delivered
- The company was founded by Harvard dropouts and operates its own data centers (per @pstAsiatech)
- Etched focuses on Transformer-specific inference chips, using fixed circuitry for maximum inference efficiency; @vaibhavbetter reviewed the company's three-year journey
Why it matters
- At a $21B valuation with real deliveries underway, Etched has joined the top tier of chip startups and its Sohu architecture is moving into deployment; the one-month valuation doubling reflects intense capital interest in inference chips
- Citing MattGialich, @AviatorAshley reminds readers that first-order derivatives of the supply chain — raw materials, power and other infrastructure — matter as much as the chip companies themselves
