Salience Labs, a photonics startup building optical switching technology for AI data-centre connectivity, raises an oversubscribed $125 million Series B. The round is led by Bullhound Capital, with participation reported from AMD Ventures and Intel Capital, alongside the British Business Bank. The company says the funding is intended to accelerate deployment of its optical switching and related photonic chips used for AI workloads.
Several outlets also report that Salience Labs is expanding its operations after the funding. It plans to scale manufacturing and open a second office on the West Coast, in addition to its Oxfordshire base. The coverage frames the raise as a step toward scaling circuit-switching capabilities for data-centre interconnects, following technology demonstrations highlighted by at least one outlet.
Across the reports, the main emphasis is consistent on the size and structure of the funding round and on operational scaling, with outlet differences mainly reflecting the degree of detail on the company’s photonic switching approach and the reasons cited for growth. The reporting does not indicate changes to product direction beyond expanding manufacturing and presence.
