总部位于帕洛阿尔托的初创公司CScale正在为AI数据中心构建光互连技术，现已结束隐身模式，完成1.45亿美元的C轮融资。该公司周三在声明中表示，本轮融资使其总融资额达到1.88亿美元。
CScale, a Palo Alto startup building optical interconnect for AI data centres, has come out of stealth with $145m in Series C funding. The round takes its total funding to $188m, the company said in a statement on Wednesday.
Atreides Management领投本轮融资，Valor Equity Partners和Premji Invest共同领投。自CScale成立起便支持该公司的Sutter Hill Ventures以及Maverick Silicon也参与了投资。Nvidia和Intel Capital作为其首批战略投资者加入。
Atreides Management led the round, with Valor Equity Partners and Premji Invest as co-leads. Sutter Hill Ventures, which has backed CScale since it started, and Maverick Silicon also took part. Nvidia and Intel Capital joined as its first strategic investors.
首席执行官Martin Lund表示：“我们正在设计用于连续性的互连技术。激光会失效，但计算不应因此中断。”
“We’re designing the interconnect for continuity. Lasers will fail. Compute shouldn’t,” chief executive Martin Lund said.
CScale构建的是什么？光互连技术使数千个加速器能够协同工作，如同一台更大的计算机。CScale表示，一旦单个AI系统跨越数十个机架，这些链路就变得至关重要。该公司正在为此构建集成光引擎。
What CScale builds Optical interconnect is what lets thousands of accelerators work together like one much larger computer. CScale says those links become essential once a single AI system spans dozens of racks. It is building an integrated light engine for that job.
其核心卖点是可靠性。CScale表示，其设计的互连技术旨在容纳光故障而不中断计算。
Its pitch is reliability. CScale says it is designing the interconnect to contain optical failures without interrupting compute.
Atreides的管理合伙人兼首席投资官Gavin Baker表示：“每一次光故障都是计算故障。”该公司表示，这笔资金将用于技术开发和市场推广。
“Every optical failure is a compute failure,” said Gavin Baker, managing partner and chief investment officer at Atreides. The money will go on developing the technology and bringing it to market, the company said.
谁在管理？Lund曾建立Broadcom的交换业务，并在Microsoft和Cadence担任高级职务。最近，他领导Cisco的通用硬件组，该组涵盖硅片、硬件系统和光学技术。
Who runs it Lund built Broadcom’s switching business and held senior roles at Microsoft and Cadence. Most recently he ran Cisco’s Common Hardware Group, which covers silicon, hardware systems and optics.
联合创始人兼首席技术官Sanjai Kohli共同创立了SiRF，该公司将GPS推向大众市场。他后来创立了Inovi，该公司于2014年被Facebook收购。CScale成立于2023年，拥有约85名员工。
Founder and chief technology officer Sanjai Kohli co-founded SiRF, which brought GPS to the mass market. He later founded Inovi, which Facebook bought in 2014. CScale was founded in 2023 and has about 85 employees.
CScale加入了一连串为连接AI芯片的初创公司的大额融资行列。Atreides还投资了Lumilens，后者在8月融资7亿美元。Celero本月融资2.75亿美元，Eliyan在7月完成了1.45亿美元的C轮融资。Nvidia也在押注光子学技术。
CScale joins a run of big rounds for startups that wire AI chips together. Atreides also backed Lumilens, which raised $700m in August. Celero raised $275m this month, and Eliyan took a $145m Series C in July. Nvidia has also been betting on photonics.
