UK-based AI infrastructure company Nscale has closed a $433 million (£320m) pre-Series C SAFE, only days after raising $1.1 billion in what was described as the largest Series B round in European history.

The funding brings in support from investors including Blue Owl Managed Funds, Dell, NVIDIA and Nokia, alongside other backers from the earlier round.

The London-based business, which operates more than 50 data centres and manages one of the world’s largest GPU pipelines, says the additional capital will reinforce its ability to deliver vertically integrated compute, networking, storage and AI services at scale.
