What happened

Upscale AI, a pure-play AI networking infrastructure company, announced $190 million（約300億円） in Series A-1 financing led by Premji Invest, with participation from NVIDIA, Salesforce Ventures, Seligman Ventures, Temasek, and existing investors. This brings the company's total funding to $500 million（約800億円） and its current valuation to $2 billion（約3200億円）.

Why it matters

The company is building a full-stack AI networking solution—spanning silicon, systems, and software—designed to connect accelerators, memory, and storage into a single high-performance engine for large-scale, synchronized AI workloads like training and inference of frontier models. Investors view networking as one of the most critical bottlenecks in AI infrastructure at cluster scale.

What to watch

The company will use the new capital to accelerate delivery of its open-standard AI-native networking technology.
