Eridu

Eridu is a Saratoga, California company building networking silicon and switch systems purpose-built for AI data centers. It designs its switch from a clean sheet across silicon, systems and software, consolidating functions that normally require tiered optical interconnects onto a single chip to cut power, cost and latency while raising radix and reliability. The company was founded in 2023 by Drew Perkins, Omar Hassen and Mike Capuano, and emerged from stealth in March 2026 with an oversubscribed $200M Series A led by Socratic Partners, John Doerr and Matter Venture Partners, bringing total funding to about $230M.

A clean-sheet switch architecture designed at the silicon level for AI traffic rather than an incremental step on general-purpose merchant switch chips, targeting an order-of-magnitude gain in performance, radix and efficiency to close the gap between GPU compute growth and stagnant switch bandwidth.
