Eridu, an AI networking company building infrastructure designed specifically for large-scale artificial intelligence systems, has emerged from stealth with more than $200 million in funding to address a growing bottleneck in AI data center performance.
The oversubscribed Series A round was led by Socratic Partners and included participation from investors such as John Doerr, Hudson River Trading, Capricorn Investment Group, Matter Venture Partners, Bosch Ventures, Eclipse Capital, Fusion Fund, MediaTek, Osage University Partners, SBVA, TDK Ventures, VentureTech Alliance, and Zelda Ventures, among others.
Founded by networking industry veterans, Eridu is developing a new architecture for data center networking to support the rapidly expanding demands of generative AI workloads. The company says existing networking infrastructure is failing to keep pace with advances in AI compute, creating a “network wall” that limits performance, increases latency, and raises operational costs.
The company’s approach introduces a clean-sheet design for AI networking, including a high-radix switch architecture intended to dramatically increase throughput and reduce infrastructure complexity. According to the company, the system can replace dozens of conventional switches while improving GPU utilization and reducing both power consumption and capital expenditures.
Eridu says its architecture enables single-hop scale-up domains containing thousands of GPUs and scale-out domains capable of supporting millions of GPUs. By reducing the number of networking tiers and simplifying system design, the company believes its technology can lower latency, decrease network jitter and accelerate AI data center deployment.
The company estimates its technology could deliver up to 40 percent savings in capital expenditures and up to 70 percent reductions in networking power usage compared with conventional networking architectures.
The new funding will be used to complete development of Eridu’s networking platform and bring the system to market as demand for large-scale AI infrastructure continues to surge among hyperscalers, AI research labs and emerging cloud providers.
Eridu says its solution is designed primarily for hyperscale AI data centers but could also be deployed in sovereign clouds, neocloud platforms and large enterprise AI environments.
KEY QUOTES
“The disruptive demands of AI create an urgent need for completely re-thinking high-speed interconnect and packet switching. Eridu’s novel architecture dramatically improves throughput and is a platform that nearly all next generation AI will depend on. The team’s deep expertise, systems engineering skills, and execution track record lend credibility to delivering the first new switching and interconnect platform built specifically for generative AI.”
Gregory Waters, Managing Partner, Socratic Partners
“Billions of dollars of investment in AI data centers are being wasted because of the network wall. The plodding pace of improvement promised by the existing industry vendors is simply inadequate to solve the problem. Even new companies and solutions promising higher performance are in fact still subscale. Eridu has taken on and solved the key challenges across silicon, packaging, systems and optics needed to break through that wall.”
Drew Perkins, CEO And Founder, Eridu
“AI requires a new generation of infrastructure that Eridu is pioneering. Eridu’s team of industry veterans is proven – in prior companies (Lightera, Infinera), they have delivered billions of dollars in networking innovation.”
John Doerr, Venture Capitalist And Chairman, Kleiner Perkins
“We are excited to work with Eridu as it executes its vision to deliver advancements in AI networking, using TSMC’s advanced process and advanced system integration technologies. This partnership reflects TSMC’s commitment to supporting startup innovators like Eridu by combining our semiconductor manufacturing excellence with their expertise in system architecture innovation, driving breakthroughs in high-performance networking for AI datacenter infrastructure.”
Dr. Lucas Tsai, Vice President Of Business Management, TSMC North America
“Today’s cloud networking gear is clearly insufficient for the bandwidth demands of accelerated compute. As larger MoE models and trends like disaggregation of prefill and decode emerge, demands for network bandwidth and scale are only accelerating. Eridu’s networking technology is purpose-built for massive AI scale, supporting both scale-out and scale-up, enabling more bandwidth, larger AI clusters and lower costs. Eridu is the first company I’ve seen with the team and vision to deliver the next level of interconnect scale required to meet the insatiable demands of accelerated compute.”
Dylan Patel, Founder And CEO, SemiAnalysis
“Our track record of success has been based on investing in teams with a bold vision to disrupt the status quo. The Eridu team has impressed us not only with a bold vision for AI networking that stands out from the market; they have also shown us that they’ve been able to solve the hard technology challenges needed to deliver on that vision.”
Dipender Saluja, Managing Partner, Capricorn Investment Group’s Technology Impact Fund
“Breaking through the networking bottleneck facing AI data centers is the kind of critical HardTech challenge our firm was built to help founders solve. Eridu AI is on a compelling path to overcome this constraint, potentially unlocking billions of dollars in AI infrastructure value while enabling the next phase of more efficient large-scale AI deployment.”
