Amperesand, which focuses on next-generation power infrastructure for data centres and critical power applications, has raised US$80m (€69m) in a Series A round led by Singaporean investment firm Temasek and US venture capital investor Walden Catalyst Ventures.
The funding will be used to deploy 30MW of commercial systems throughout 2026, starting with the delivery of the company’s first commercial units to the Port of Singapore in early 2026.
In 2025, Amperesand, which was incubated by Xora Innovation, a Singapore-based technology investor, and spun out of Singapore’s Nanyang Technological University in 2023, established engineering and manufacturing hubs in San Francisco and Reno in the US.
Phil Inagaki, managing partner and CIO at Xora, said: “The company is now ready to deploy a product that will completely redefine power infrastructure across mission-critical industries.”
Inagaki added: “With US$80m in fresh funds and an aggressive deployment schedule in 2026 across multiple customers, we expect Amperesand will extend its lead as the solid-state transformer category leader.”
Young Sohn, founding managing partner at Walden Catalyst Ventures, said: “AI is redefining the limits of computing. But without a revolution in power infrastructure, this growth simply can’t scale. Amperesand is tackling one of the biggest bottlenecks in data centre power delivery by leveraging new high-power, semiconductor-enabled technologies for faster, more efficient, and more sustainable access to energy.”
Brian Dow, CEO and co-founder of Amperesand, said: “In this era of AI data centre and other critical power systems becoming economic and national security interests for many countries, Amperesand’s medium voltage solid-state transformer platform enables in-country cyber-secure controls and data, regionally available supply chains, and low Capex intensity local manufacturing.”
