THE HOOK
Another $88M bet that light, not copper, breaks the AI memory wall.
THE GIST
Volantis closed an $88M Series A co-led by Lachy Groom and Abstract Ventures (John Doerr, Dwarkesh Patel, Naveen Rao among participants). Its A-1 system targets models over 20 trillion parameters at up to 10,000 tokens/sec per user via photonic interconnects. First customer engines planned for 2027.
THE TAKE
Memory bandwidth is the real tax on giant models, and Volantis is selling an optical escape hatch. Micro-VCSELs and picojoule-per-bit links sound great on a press release. Shipping integrated inference engines in 2027 is the part that sorts hype from hardware.
OPINION
Founders from NVIDIA, AMD, Broadcom and Ayar Labs know the CoWoS and VCSEL supply chains — that’s the credibility. Still treat the PR as a fundraising milestone, not a shipping date. Watch who signs A-1 LOIs before the silicon story gets real.
