Volantis, a four-year-old chip startup, has raised $88 million in Series A funding to develop photonic interconnects for AI processors, aiming to address the memory wall problem.
TL;DR
- Volantis raises $88M Series A to develop photonic interconnects for AI processors.
- The funding will support the development of light-based connections to address the memory wall problem in AI.
- Volantis joins a competitive landscape of companies working on optical interconnect solutions.
What happened
Volantis, a Silicon Valley-based chip startup, announced a $88 million Series A funding round on October 1, 2026. The round was co-led by Lachy Groom and Abstract Ventures, with participation from notable investors such as John Doerr, VXI Capital, Triatomic, and Susa Ventures. The funding brings the company's total funding to $97 million.
Volantis is developing photonic interconnects that use light to connect AI processors and memory, aiming to eliminate the memory wall problem. The company claims its technology can place far more memory within reach of a single processor than conventional electrical packages allow.
Why it matters
The memory wall problem is a significant bottleneck in AI performance, as AI chips often compute faster than they can be fed data. Volantis's photonic interconnects aim to address this issue by using light to move data more efficiently.
The competitive landscape for optical interconnects is crowded, with several well-funded players chasing similar goals. Volantis's funding round positions it as a significant player in this space, but the company has not yet demonstrated its technology in a commercial product.
For developers and startups, the development of photonic interconnects could lead to more efficient and powerful AI systems. For investors, the race to solve the memory wall problem presents both opportunities and risks, as the technology is still unproven.

Context
The memory wall problem has become increasingly urgent as large language models scale into the trillions of parameters. Running inference on these models requires shuttling enormous blocks of data between memory and the processor, creating a bottleneck that limits performance.
Traditional high-bandwidth memory (HBM) has physical limits that constrain the amount of memory that can be placed within reach of a single processor. This has led to a shortage of HBM and a search for alternative solutions, such as photonic interconnects.
Volantis is one of several companies working on optical interconnect solutions. The competitive landscape includes companies like Ayar Labs, Lightmatter, and Celestial AI, each pursuing different approaches to the problem.
