Salience Labs raises $125M Series B for AI data center switching tech

Salience Labs, a developer of all-optical circuit switching technology for artificial intelligence data centers, closed a $125 million Series B funding round led by Bullhound Capital. The technology is designed to address performance constraints in large-scale AI infrastructure by improving how data flows between servers and computing resources.

Optical circuit switching represents an emerging approach to networking that uses light to route data more efficiently than traditional electrical switches, potentially reducing latency and power consumption in data centers running compute-intensive AI models.
