Amperesand, a leader in power infrastructure for AI data centres, has announced the successful closure of an $80m Series A funding round, co-led by Walden Catalyst Ventures and Temasek. This funding, the largest ever for a Solid State Transformer (SST) company, will enable Amperesand to focus on deploying 30MW of commercial systems by 2026, targeting hyperscale AI customers with critical power needs.
The investment round also saw participation from new investors such as Industry Ventures, Acclimate Ventures, and SG Growth Capital, alongside existing backers like Xora Innovation and TDK Ventures. Amperesand’s Medium Voltage Solid-State Transformer (MV SST) platform promises significant advancements in power density, efficiency, and scalability, crucial for AI data centres and other high-demand applications.
Young Sohn, Founding Managing Partner at Walden Catalyst Ventures, stated, “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.”
Amperesand plans to expand its engineering and manufacturing operations in the US and Singapore to meet the growing global demand for its critical power solutions. The company, which was incubated by Xora Innovation and spun out of Singapore’s Nanyang Technological University in 2023, has already secured multiple commercial pilots for 2026.
Phil Inagaki, Managing Partner at Xora, noted, “With $80m in fresh funds and an aggressive deployment schedule in 2026 across multiple customers, we expect Amperesand will extend its lead as the SST category leader.”
