Value proposition

Eliminates 'last-inch' power delivery bottlenecks by delivering power vertically underneath the processor, reducing resistive losses and heat while enabling significantly higher rack density and power efficiency (up to 99%).

Products and solutions

Hybrid Switched-Capacitor (HSC) Power Modules, Vertical Power Delivery (VPD) Architectures, High-Efficiency DC-DC Converters, AI-Optimized Power Management ICs (PMICs)

Unique value

Replaces traditional bulky inductor-based systems with a streamlined hybrid switched-capacitor (HSC) architecture that allows for a low-profile, thin form factor suitable for vertical placement directly beneath the chip.

Target customer

Hyperscale data center operators (e.g., AWS, Google, Meta), AI chip designers (GPU, TPU, and NPU manufacturers), and high-performance computing (HPC) infrastructure providers.

Industries served

Semiconductors, Artificial Intelligence, Data Center Infrastructure, Cloud Computing

Technology advantage

Achieves industry-leading efficiency of 98%-99%, significantly reducing the thermal footprint of AI racks and allowing hyperscalers to scale toward multi-megawatt data center configurations without traditional power delivery constraints.

How they differentiate

Utilizes proprietary Hybrid Switched-Capacitor (HSC) technology to eliminate bulky inductors, enabling ultra-thin 'Vertical Power Delivery' (VPD) directly under the processor with up to 99% efficiency.

Main competitors

Vicor Corporation, Monolithic Power Systems (MPS), Infineon Technologies

Key partnerships

Seligman Ventures (Lead Series A investor), Intel Capital, AICONIC Ventures, Cambium Capital, A&E Investments, Assam Ventures, Nepenthe Capital

Notable customers

Major milestones

Emerged from stealth in March 2024, Secured $21M Series A funding led by Intel Capital and Seligman Ventures, Developed breakthrough Hybrid Switched-Capacitor (HSC) architecture for AI power delivery

Growth metrics

Emerged from stealth in March 2024; expanded team to 11-50 employees with leadership from former Lion Semiconductor and Dialog Semiconductor executives.

Market positioning

Deep-tech semiconductor innovator targeting the 'last-inch' power delivery bottleneck in AI data centers.

Geographic focus

North America (Silicon Valley HQ) and Global (targeting AI chipmakers and hyperscalers in Asia and Europe).

Patents and IP

Founding team holds extensive IP in high-performance IC design and switched-capacitor technology; company has filed for trademarks (EPIC MICRO™) and is building a proprietary portfolio around vertical power delivery packaging.
