About Eridu

Eridu is a Silicon Valley-based hardware startup pioneering infrastructure solutions that accelerate AI data centers to deliver Faster AI. Today’s AI performance is frequently limited by communication bottlenecks. Eridu delivers multiple industry-first innovations across silicon, packaging, software, and systems to deliver a step function in AI networking – a network switch that is an order of magnitude improvement in bandwidth and radix versus today’s “state of the art” switches. This is the first silicon and system designed from the ground up for AI and the increase in radix and throughput unlocks greater GPU utilization to speed training job completion times and tokens‑per‑second for more profitable inference. We do this while simultaneously reducing capital and power costs, improving reliability, simplifying operations and speeding AI data center deployments for faster time to revenue.

The company’s solutions and value proposition have been widely validated by leading hyperscalers.

The company has raised $200M to date including its most recent, oversubscribed Series A round led by Socratic Partners, John Doerr, Hudson River Trading, Capricorn Investment Group and Matter Venture Partners, with participation by SBVA, MediaTek, Bosch Ventures, TDK Ventures, Eclipse Ventures, and VentureTech Alliance, among others.
