AI networking startup Eridu has officially emerged from stealth with a heavily oversubscribed $200 million Series A funding round. Led by Socratic Partners, legendary venture capitalist John Doerr, and Matter Venture Partners, this latest investment brings Eridu's total capital raised to $230 million. The company was founded in 2024 by Drew Perkins and Omar Hassen to address critical bottlenecks in artificial intelligence infrastructure. Drew Perkins brings decades of experience in computer networking, having co-founded the Point-to-Point Protocol and built successful companies such as Lightera Networks, Infinera, and Gainspeed. After discussing the massive compute requirements of AI models like ChatGPT with OpenAI CEO Sam Altman, Perkins realized that future AI growth would be limited not just by chip availability, but by how those chips communicate. He identified that traditional networking methods introduce latency and reliability issues that hinder the exponential progress of GPU compute and memory bandwidth. To solve this, Eridu is developing a new class of silicon designed specifically for AI data centers. The startup aims to replace traditional tiered optical connections with integrated on-chip communications. By moving more networking functions directly onto the chip, Eridu promises to reduce power consumption, lower costs, and significantly improve network reliability, as optical components are often the weakest link in current systems. The company plans to sell complete switch systems that will replace existing gear from providers like Arista Networks, Broadcom, and Cisco. The founding team also includes Omar Hassen, a networking chip design veteran with experience at industry giants Broadcom and Marvell. Their deep technical expertise attracted a wave of interest from prominent investors. Wen Hsieh of Matter Venture Partners was a key investor, introducing John Doerr, who had previously backed some of Perkins' earlier ventures. The round also includes participation from Hudson River Trading, Capricorn Investment Group, MediaTek, Bosch Ventures, TDK Ventures, Eclipse, and VentureTech Alliance, the investing arm of chip fabrication leader TSMC. Perkins declined to comment on the company's specific valuation, noting only that it aligns with other Series A deals of similar size. While he would not confirm if Eridu has achieved unicorn status with a valuation exceeding $1 billion, the strong demand suggests the market views the company's approach as vital for the upcoming era of massive data center expansion. With a current workforce of around 100 employees, Eridu aims to leverage the founders' extensive industry background to deliver a reliable, high-performance networking solution tailored for the demands of next-generation AI.
