Optalysys, a photonic computing company, has raised £23 million in a Series A extension round.
The round was led by Northern Gritstone with participation from imec.xpand, Lingotto Horizon, and the UK government’s National Security Strategic Investment Fund (NSSIF).
The investment will be used to accelerate the commercialisation of Optalysys’ proprietary photonic chips and support expansion into the US.
Leeds-based Optalysys initially raised £21m in Series A funding in 2023 while former Arm CTO Dipesh Patel was appointed chair of its board last year.
