Salience Labs raises $125M Series B for optical AI switches

Salience Labs, a photonic chip startup based in Milton, Oxfordshire, closed an oversubscribed $125 million Series B led by Bullhound Capital. Intel Capital and AMD Ventures invested through their arms; SBI Group, Hudson River Trading and the British Business Bank joined as new investors, with Applied Ventures, Oxford Science Enterprises, Cambridge Innovation Capital and Silicon Catalyst Ventures returning. Bullhound principal Callum Stewart joins the board. The company said the money will fund volume manufacturing, denser 128-port and 256-port switch versions, and a second West Coast office in Silicon Valley. Salience showed a live 64-port switch at ECOC 2026, which it calls an industry first for silicon photonics optical circuit switching, and says it will keep working with Keysight Technologies and Tower Semiconductor to scale manufacturing.
