Relativity Networks, the leading at-scale provider of next-generation fiber-optic technology, has announced an oversubscribed $6.1M seed funding round that includes Prysmian, the global provider in energy and communications cables, GOVO Venture Partners, and a group of new and previous investors who invested in Relativity's pre-seed round.

This brings the company's total amount raised to $10.7M, validating and reinforcing the company's ability to produce and deliver, at scale, the hollow-core fiber (HCF) cable increasingly in demand by operators of the energy-intensive data centers required for the AI economy.

The seed round comes on the heels of rapid growth for the company, which emerged from stealth in February with a $4.6M pre-seed funding round.
