What Amperesand does

Amperesand is a Singapore-headquartered deep-tech company that manufactures Medium Voltage Solid-State Transformers (MV SSTs) for hyperscale AI data centres and critical infrastructure operators. Spun out of Nanyang Technological University (NTU) Singapore in 2023 from ERI@N research programmes funded by Singapore's National Research Foundation, the company consolidates multiple traditional electrical infrastructure components — transformers, power electronics, switchgear — into a single factory-built unit that replaces the conventional multi-vendor, multi-timeline deployment model with a "one vendor, one timeline, one integration" architecture delivering medium-voltage power from grid to rack for AI factories. The platform is built on silicon carbide (SiC) power modules and targets global 800V DC AI factory architectures, supporting GPU racks exceeding 100 kW today with a stated trajectory toward 1 MW per rack by 2030.

The technology stack centers on >98.5% MV AC-to-LV DC conversion efficiency, a proprietary redundancy architecture engineered for 99.999% uptime, and dynamic grid integration with instantaneous on/off-grid switching and cyber-secure connected operation. Amperesand holds 18 patent families developed over 10+ years of R&D and operates the Singapore Solid State Systems Innovation Center (S4IC), the San Francisco Power Electronics Innovation Center, and the Reno Design and Advanced Manufacturing Center (UL/IEC/IEEE certified). The company's stated benefits versus traditional infrastructure include 5x faster time-to-power and a 50% reduction in equipment footprint. A second-generation system has completed full-power, overload, and bidirectional testing ahead of initial commercial deliveries scheduled for 2026.

Amperesand runs an enterprise direct field-sales motion targeting Fortune 100 hyperscale customers and critical infrastructure operators, with revenue generated through capital-equipment sales of SST hardware units and a stated 2026 deployment target of 30 MW of commercial systems. Named flagship engagements include the PSA unboXed port-electrification pilot at the Port of Singapore (first commercial delivery in early 2026), the STT GDC FutureGrid Accelerator HVDC testbed with Liteon, and undisclosed Fortune 100 hyperscaler deployments. The company has raised over $100M in total funding across a $12.45M seed round (Feb 2024) led by Material Impact and Xora Innovation and an $80M Series A (Nov 2025) co-led by Walden Catalyst Ventures and Temasek, with participation from Industry Ventures, Acclimate Ventures, SG Growth Capital, TDK Ventures, and Foothill Ventures. Headcount is projected to exceed 100 employees globally in 2026, and a Gen 5 platform is in development for utility-scale grid applications.

Direct peers

• DG Matrix: DG Matrix is a fellow solid-state transformer startup and a co-founding member of the Data Centre Power Coalition alongside Amperesand. It pursues the same medium-voltage SiC-based SST opportunity for AI data centers and critical infrastructure, making it the most direct peer in the market.

Broad incumbents

• Hitachi Energy: Hitachi Energy is a global leader in power transformers, grid integration, and power electronics with active solid-state transformer programs. It is also a co-founding member of the Data Centre Power Coalition with Amperesand and serves the same hyperscale and utility customers, but from a broad incumbent position.
• ABB: ABB is a major power and automation company with established transformer, power-electronics, and data-center infrastructure portfolios. It competes with Amperesand across medium-voltage power delivery and has active efforts in solid-state and power-conversion technologies serving utility and hyperscale customers.
• Siemens Smart Infrastructure: Siemens Smart Infrastructure supplies transformers, power conversion systems, and data-center power solutions to hyperscalers and utilities globally. It is a broad incumbent competing in the same medium-voltage power delivery and SST-adjacent categories that Amperesand targets.
• Schneider Electric: Schneider Electric is a leading data-center infrastructure provider (Galaxy UPS, MV/LV switchgear, power distribution) and overlaps with Amperesand's value proposition of integrated, factory-built power infrastructure for hyperscale AI customers. It is a broad incumbent rather than a direct SST specialist.
• Eaton: Eaton is a major power management company with a broad portfolio in transformers, switchgear, UPS, and data-center power distribution. It is an incumbent alternative to Amperesand for hyperscale and industrial customers evaluating integrated medium-voltage power solutions.
• Vertiv: Vertiv specializes in critical digital infrastructure including power, thermal, and IT systems for data centers. While it does not currently sell solid-state transformers, it is a key incumbent competing for the same hyperscale AI data-center power infrastructure wallet.

Others

• Generac Industrial: Generac is a major manufacturer of power generation and energy storage systems and the prior employer of Amperesand's CEO and SVP of Engineering. It is adjacent rather than directly competitive, but it represents a potential acquirer or strategic partner in the medium-voltage power electronics space.
• TDK Corporation (parent of TDK Ventures): TDK is a major electronic-components manufacturer and a backer of Amperesand through TDK Ventures. It supplies passive components and power electronics modules into the same data-center and industrial customers, making it both a potential supplier/strategic partner and an indirect adjacent player.
