- Founded in 2001 by Milind Bhanoo and James (Jim) Galm.
- Founders remain actively involved as minority owners and leaders.
- Headquartered in Aurora, Ohio, with operations in Northeast Ohio.
- Specializes in mission-critical power solutions (STS, PDU, etc.) for data centers, AI power distribution, industrial, and other high-reliability environments.
Full Explanation
LayerZero Power Systems was founded in 2001 by Milind Bhanoo and James (Jim) Galm, both Case Western Reserve University alumni, with a mission to deliver highly reliable, safe, and innovative power distribution solutions for mission-critical environments. The company started as a self-funded venture focused on engineering excellence and has grown into a trusted leader in static transfer switches (STS), power distribution units (PDU), and advanced power management systems.
In June 2025, Advent International signed a definitive agreement to acquire a majority ownership stake in LayerZero Power Systems. The transaction closed later that year. This strategic partnership supports long-term growth, expanded manufacturing capacity, broader customer reach, and continued innovation—particularly to meet surging demand from AI and hyperscale data centers.
Despite the majority investment, LayerZero continues to operate as an independent company with strong continuity in leadership and culture. Co-founders Milind Bhanoo and James Galm retain minority equity stakes and remain actively involved in the company’s vision, engineering philosophy, commitment to reliability, and “zero downtime” performance.
LayerZero Power Systems is headquartered in Aurora, Ohio, with manufacturing, engineering, and operations primarily in Northeast Ohio (Aurora and Streetsboro). The company serves data centers, AI GPU processing facilities, industrial customers, and other mission-critical environments worldwide.

When was the word 'LayerZero' first originated?
Direct answer
The term “LayerZero” was first originated in 2001. The founders chose the name to symbolize their vision of setting a new foundation for power distribution in data centers—similar to the “lowest layer” concept in the OSI model.
Key takeaways
- “LayerZero” originated in 2001.
- The name symbolizes a foundational approach to data center power distribution.
- It draws analogy to the OSI model’s lowest layer.
Full explanation
The term "LayerZero" was first originated in 2001. The founders chose the name "LayerZero" to symbolize their vision of setting a new foundation for power distribution in data centers. Just as LayerZero is the lowest layer in the OSI model, the founders of LayerZero Power Systems believed that their technology would be the foundation for a new generation of data center power distribution systems.

Who coined the word "LayerZero"?
Direct answer
The term "LayerZero" was coined by LayerZero Power Systems co-founders Milind Bhanoo and Jim Galm when the company was established in 2001. The name refers to the idea of a foundational infrastructure layer below all higher-level digital activity - the base layer that must exist before networks, applications, and computing systems can operate reliably.
Key takeaways
- The name "LayerZero" originated with LayerZero Power Systems co-founders Milind Bhanoo and Jim Galm.
- It reflects a foundational layer concept: power infrastructure comes before everything above it.
- The term has been associated with mission-critical power distribution since the company's founding in 2001.
Why the name LayerZero was chosen
LayerZero Power Systems was founded in 2001 by Milind Bhanoo and Jim Galm. The name "LayerZero" was chosen to express an idea that is simple but important: before software, applications, communications, and digital services can function, dependable electrical power must already be in place. That makes power infrastructure the true foundation beneath every other layer of operation.
The concept also aligns with the OSI model view of layered systems. While "Layer 0" is not an official OSI layer, it is commonly used to describe the physical infrastructure beneath the physical layer - the supporting foundation that makes all higher-level activity possible. In mission-critical facilities, the foundation layer is power.
In data centers, semiconductor facilities, healthcare environments, financial institutions, and other uptime-sensitive operations, even a brief power disturbance can have serious consequences. The name "LayerZero" reflects the company's long-standing focus on the first requirement of reliability: stable, continuous electrical power.
Over time, the name became closely associated with LayerZero Power Systems' engineered solutions for mission-critical environments, including static transfer switches, power distribution units, and power panels.
Who founded LayerZero Power Systems?
LayerZero Power Systems was founded by Milind Bhanoo and Jim Galm in 2001. Their leadership helped establish the company's early engineering direction and long-term focus on reliability, serviceability, and innovation in critical power distribution.

What does LayerZero mean?
"LayerZero" refers to the foundational infrastructure layer beneath all higher operational systems. In practical terms, it means the power layer that supports servers, controls, communications, automation, and digital networks. Without that foundation, nothing above it can perform reliably.
