The Power Solution Company

Bringing physical AI to the power layer

Progress has always been limited by the power available to it. We exist to lift that limit.
Mission

Reinvent power distribution, so every building, site and grid gets more from its power.

Solid-state hardware that senses, learns and acts in microseconds, in every node, so nothing moves that we cannot see. Data centers first. The grid is the end game.

Vision

A grid ready for whatever the world asks of it next.

We are working to ready the grid, the backbone that underpins our society, for what comes next.

Why now

The constraint on AI is no longer chips

Today’s data center power distribution equipment has no brain, no awareness, and no ability to learn. It was built for a world before AI-scale server racks, and its inefficiencies show it: stranded circuit capacity, conversion losses, and a footprint that grows every time power density climbs.
Merge4 was founded to fix that at the layer where it originates. Physical AI in the power layer is only possible on solid state, because electromechanical hardware cannot sense, learn, or act fast enough. So we built the hardware from first principles, and made intelligence native to it.
Why we exist

Progress runs on power.

Everything we are trying to build next, every model trained, every town electrified, every mile driven, arrives at the same question. Is there power for this? Increasingly, the answer is no.

The problem

Communities know this before anyone tells them. They fight new projects because they can see what is coming: higher bills, drained water, a grid that fails on the day it matters.

The layer that distributes power has not been rethought in a century. It converts, and every conversion becomes heat. It cools that heat with water. It fills rooms with metal that has to move to work. It passes every surge straight out to the grid.

What we changed

So we changed it. Power that goes DC stays DC. Protection with no moving parts. Intelligence in every node, acting in microseconds, catching a surge before it ever leaves the building.

Data centers first, because that is where the limit is biting hardest today. The grid after, because it is the backbone under everything else.

Cooler.
Smaller.
Steadier.

A facility that communities can live beside.

Power Reinvented.

Values

How we work

01
Rigor
Every claim we make comes with the evidence behind it. We tell you what is still being proven as plainly as what is settled.
02
Curiosity
We question assumptions the industry has carried for a century, so you get protection designed for today and tomorrow.
03
Clarity
Power is complicated. We explain it plainly, whether you are an engineer, an executive or a neighbor of the site.
04
Pragmatism
We build around the equipment you already run and the timeline you are working to, so adopting Merge4 never means starting over.
05
Consequence
Your power reaches beyond your site. We design for the grid, the region and the people who live alongside it, not just the load in front of us.
Why us

We have spent our careers between two industries that do not understand each other.

The power industry does not understand software. The software industry does not understand power. Merge4 was built by people who have shipped in both industries.
Then

We have seen this pattern before

Our founders started in telecom in the 1990s, watching a regulated industry deregulate while a disruptive technology and a disruptive business model arrived at the same time. Everything that followed came out of that: distributed energy, smart grid research, microgrids, bidirectional charging, and solid-state roadmaps built for some of the largest names in electrical equipment. The same pattern is repeating in energy now, and we recognized it early.

Now

Built from first principles

We knew which algorithms we needed to train before we laid down a single chip, because physical AI cannot be added to hardware that was not designed for it. We designed the UL strategy into the first architecture decision rather than bolting it on, because UL is what levels the playing field and gets a product deployed. Eight patents cover the result, including hot-swap at 800 VDC.

That is why we were positioned to build this, and why it took a team that has lived in both worlds to do it.
