Empower Semiconductor makes tiny power management chips that control how electricity is delivered to the processors inside data center servers. Their technology helps AI chips run more efficiently by reducing wasted energy, which is a growing problem as AI processors consume more and more power.

Traditional power management requires bulky external components on the motherboard, but Empower's integrated voltage regulators are compact enough to be integrated directly into the processor package, dramatically shrinking the footprint. Their chips also perform dynamic voltage scaling significantly faster than competitors, reducing wasted power during workload transitions.

As AI processors consume increasingly massive amounts of power — with chips pushing past 2 kilowatts — Empower's technology has become critical for enabling the next generation of AI accelerators to operate efficiently within data center power budgets. Empower closed over $140M in Series D financing led by Fidelity in September 2025, bringing total funding past $200M, and in December 2025 expanded globally with a new Silicon Valley headquarters and a Munich R&D office to meet surging AI demand.
