Volantis Raises $88M Series A for Photonic AI Chip Interconnect

Volantis Secures $88 Million Series A

Volantis, a semiconductor startup building a photonic interconnect that links AI compute chips directly to memory, has raised $88 million in Series A funding. The round was led by Lachy Groom and included participation from Triatomic Capital, Susa Ventures, John Doerr, VXI Capital, Abstract Ventures, Sholto Douglas, Dwarkesh Patel, and Naveen Rao. The funding date is October 1, 2026.

Technology and Product

Volantis is developing a photonic interconnect that connects AI compute chips directly to memory. The company uses custom micro-VCSEL lasers to break the capacity-versus-bandwidth tradeoff that limits GPU-based inference. Its first system, A-1, is designed to run models with more than 20 trillion parameters at up to 10,000 tokens per second per user. First customer deliveries are planned for 2027.

The company builds on VCSEL laser technology that is already mass-produced for smartphone facial recognition, providing a foundation of proven manufacturability.

Leadership

Volantis is led by CEO Tapa Ghosh.

Acquisition Relevance

The Series A funding provides Volantis with capital to advance its photonic interconnect technology and prepare for first customer deliveries in 2027. For acquirers in the semiconductor, AI infrastructure, or high-performance computing sectors, Volantis offers a differentiated approach to overcoming memory bandwidth bottlenecks in AI inference. Its use of mass-produced VCSEL technology may reduce manufacturing risk and accelerate time to market. The company's focus on enabling large-scale AI models at high throughput positions it at the intersection of two critical trends: the exponential growth of model sizes and the need for more efficient compute interconnects.
