Upscale AI

Overview

Upscale AI is a networking startup founded in Q3 2025 building purpose-built switching infrastructure for AI data centers. Despite its recent founding, the company raised $300M across Seed ($100M) and Series A ($200M) rounds and grew to over 200 employees within months of launch — reflecting investor conviction in purpose-built AI networking as a distinct product category from general enterprise switching. Upscale AI develops both scale-up switching (SkyHammer, for intra-GPU-cluster communication) and scale-out networking (via partnership with NVIDIA Spectrum-X), with a SONiC-based NOS strategy. The company's team claims 4+ ASIC and system generations shipped prior to forming Upscale AI.
