Back in the 2000s, Andreesen Horowitz stated that software would eat the world. At the time, I wrote that in order for software to eat the world, they would need a knife and fork. Over the last five years, we have seen that the major limitation to AI adoption has indeed been the compute infrastructure, sending stock prices of companies like the Nvidia and Arm to skyrocket.
Over the past three years, Black Opal has primarily focused on the convergence of the technology of advanced technology with applications to improve healthcare and reverse Eroom’s law in drug development. At the same time, we have kept our eye on infrastructure – the knives and forks needed to ensure these applications can be rolled out to anyone and everyone.
I have spent the majority of my 25 years working with semiconductor companies (Arm, Applied Materials, PDF Solutions) and investing in hardware tech companies like Edge Impulse, EdgeQ, Cerberas, and Mythic during my IQT days. I am thrilled to announce the first semiconductor + systems company in the Black Opal Ventures portfolio, Eridu AI.

The Network Bottleneck Throttling AI
Although AI compute is advancing in performance and scale at breakneck speed, networking is not keeping up. Demands for data movement are growing exponentially as hyperscalers, frontier labs and neoclouds pursue an all-out race to build ever-larger AI data centers. At the same time, new architectural and algorithmic innovations in AI are only making the network bottleneck worse.
Current solutions and the roadmaps promised by incumbent and new providers continue down the path of incremental enhancements to the same architecture. That path only increases latency, power demands, cooling requirements, inefficiency and costs. Networking technology has fallen so far behind that a completely new design is required.
Reengineering Networking for AI
Eridu has developed a clean-sheet design for the demands of AI. Eridu’s network switch delivers the order-of-magnitude advance in performance, radix and efficiency needed to meet current and future AI demands.
With a clean break from the limits and trade-offs of current architectures, Eridu delivers previously impossible capabilities including:
Fewer network tiers to reduce latency and network jitter
Single-hop scale-up domains with thousands of GPUs
Scale-out domains of millions of GPUs
Up to 40% savings in CapEx
Up to 70% savings in networking power
Faster deployment of AI data centers
This funding will be used to complete development of Eridu’s solution. For more information, visit eridu.ai.
