Salience Labs Ltd

Building photonic switch chips for faster, more energy efficient AI infrastructure.

Salience Labs is an Oxford spinout pioneering the use of photonic switching to overcome the data bottlenecks of modern AI. As models scale, electronic interconnects in data centres are reaching their limits, creating constraints in speed, energy efficiency and cost.

Salience Labs’ photonic switch technology uses light to move data at next-gen speeds and efficiency. Drawing on over a decade of research in silicon photonics, the company’s platform delivers optical data movement that eliminates networking bottlenecks, unlocking scalable and more sustainable AI compute infrastructure.

Led by Founders CEO Vaysh Kewada and CTO Johannes Feldmann, Salience Labs is redefining the fabric of data-centre networks, enabling faster and more energy-efficient AI workloads and powering the next generation of intelligent systems.
