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.
