EPIC Microsystems Emerges from Stealth with $21 Million from Intel Capital to Power AI Data Centres

EPIC Microsystems, a semiconductor company developing breakthrough power delivery solutions for AI infrastructure, led by Sabin Eftimie and Wonyoung Kim, has raised an oversubscribed $21 million in Series A funding to accelerate the development and commercialization of its vertical power delivery technology for next-generation AI compute platforms, led by Seligman Ventures, with participation from Intel Capital, AICONIC Ventures, Cambium Capital, and existing seed investors, A&E Investments, Assam Ventures and Nepenthe Capital, bringing the total funding to $26 million to date. As part of the investment, Umesh Padval, Managing Partner, Seligman Ventures, will join EPIC Microsystems’ Board of Directors.

Rising AI workloads push data center racks toward 1 MW, straining traditional inductor-based power solutions and forcing hyperscalers to compromise on efficiency, density, and thermal management. EPIC Microsystems’s hybrid switched-capacitor (HSC) architecture boosts efficiency, current density, and thermal performance for next-generation AI compute.

“Power density, efficiency, and thermal management are now key bottlenecks in scaling AI data centers,” said Umesh Padval, Managing Partner at Seligman Ventures. “EPIC Microsystems’s team combines deep switched-capacitor expertise with a strong understanding of data center needs, positioning their vertical power delivery architecture to meet next-generation AI demands.”

“AI data center architectures are exceeding historic power limits, and existing delivery systems can’t keep pace,” said Sabin Eftimie, Co-Founder and CEO of EPIC Microsystems. “By reimagining DC-DC power delivery, our approach improves efficiency, thermals, and rack densification, giving hyperscalers greater flexibility as rack power scales toward the multi-megawatt era. Umesh’s expertise on our Board will help us seize this unprecedented opportunity.”

“The AI compute roadmap is shaped as much by power delivery innovation as by advances in AI silicon,” said Lip-Bu Tan, CEO of Intel, seed investor in EPIC Microsystems, and veteran semiconductor leader.

EPIC Microsystems’s silicon-proven hybrid switched-capacitor design replaces bulky inductors with an efficient mix of capacitors and optimized components. The approach delivers a compact, low-profile solution optimized for rack height and current density, supporting AI accelerators and GPUs while reducing heat and improving system-level thermal management.

“As workloads grow and infrastructure densifies, foundational system architectures must be rethought,” said Andrew Tan, Board Member of EPIC Microsystems and Managing Director at A&E Investments and Salience. “Innovations in power delivery and management are key to unlocking the next decade of AI performance, and EPIC Microsystems is tackling this critical challenge.”

EPIC Microsystems was founded by industry veterans with extensive experience in power semiconductor design. The team previously pioneered switched-capacitor power solutions in the mobile market, enabling fast charging in hundreds of millions of smartphones and laptops, demonstrating a proven ability to scale advanced power architectures from innovation to high-volume production.
