> San Francisco photonics startup Volantis closed an $88 million Series A co-led by Lachy Groom and Abstract Ventures to build optical chip-to-memory interconnect for AI inference. First integrated engines are claimed for 2027 customer delivery; A-1 performance targets remain company claims without independent benchmarks.

Another sized bet that the inference bottleneck is **memory reach**, not just FLOPs — paid in venture dollars, delivered (claimed) in **2027**.

**Volantis** announced an **$88 million** Series A **co-led by Lachy Groom and Abstract Ventures**, with **John Doerr**, **VXI Capital**, **Triatomic**, **Susa Ventures**, and angels **Dwarkesh Patel**, **Naveen Rao**, and **Sholto Douglas**. The company release (PR Newswire, October 1, 09:00 ET) is corroborated on financing and thesis by a **Thomson Reuters** report (Stephen Nellis) carried via syndication. CEO/co-founder **Tapa Ghosh**; team background cited as NVIDIA / AMD / Broadcom / Ayar Labs alumni in company materials.

## Architecture pitch — company targets

Thesis: photonic interconnect (custom **micro-VCSELs**, no external lasers) linking compute to large off-chip memory pools so capacity and bandwidth rise together versus SRAM/HBM shorelines. First system **A-1** is **company-claimed** to target models **>20 trillion** parameters at up to **10,000 tokens/sec/user** and lower $/token; Reuters recounts a pitch of packing on the order of **220** memory chips around a GPU via optical reach. Volantis says first integrated inference engines go to customers in **2027**. **No independent benchmarks** verified for this draft.

Proceeds: develop and commercialize A-1 and the photonic memory architecture, expand engineering, move toward deployments — per the release.

## Limits

- Round size and investor list: **Volantis PR Newswire**, corroborated by **Reuters** (syndication full text; reuters.com canonical returned **401** this run).
- A-1 parameter, tok/s, tok/$, memory-chip-count, and 2027 delivery figures are **company targets / interview claims**, not measured shipping hardware.
- Traders Union secondary in the digest window is thinner and unused here.
