The Power Solution Company

Intelligent power distribution for the AI era

The biggest barrier to the next-generation grid is the power it requires. We deliver power through pure solid state. Transistors replace mechanical levers, so protection acts in microseconds, and footprints shrink as systems no longer need to be overbuilt to stay safe.

We are taking orders now.

From our CEO

The grid never got the transistor

Data storage, computing and telecom were each rebuilt on transistors. Power distribution was not, and it still runs on mechanical levers patented in 1924. Anna Demeo on what changes when the protection layer can finally sense, learn and adapt.

Why now

The grid was built for a world that no longer exists.

To enable an accelerating world, we now need to think about power differently and responsibly.
01

The grid

The grid is aging and outages are rising. Its infrastructure is mechanical, slow, bulky, and carries no intelligence at all. Meanwhile everything being added to it, solar, wind, EV charging and storage, is natively DC. Managing distributed resources on a decentralized, bidirectional grid needs infrastructure faster and smarter than anything installed today, and load growth from AI data centers, transportation and electrification is arriving faster than the grid can absorb it.

02

The data center

Server racks are DC native and climbing, from 15 kW to over 100 kW and heading to 500 kW. Legacy AC infrastructure is inefficient and not reliable enough to carry that. Loads swing by the megawatt in milliseconds, which shows up on the utility as flicker and delays interconnection approval. And when a facility goes down it costs roughly $8,000 per minute per megawatt.

Power distribution was designed a century ago, and it is still doing the job it was given in 1924.
The platform

We get more from power

Where the industry has always distributed power through mechanical equipment, Merge4 does it through transistors. A transistor responds in microseconds, does not arc, and because it is a computer board rather than a moving part, it can sense what is flowing through it, learn from it, and act on it. Data centers first. The grid is the end game.
01
Pure solid state
Faster, safer, and more resilient than mechanical hardware.
02
Integrated physical AI
Real-time visibility with intelligence at every node.
03
Smaller footprint
No overbuilt protection, so power equipment takes less floor.
04
Modular and scalable
Building block architecture, from megawatts to gigawatts.
What changes

Power that enables. Power that is not wasted.

Today it is power, not chips, that constrains new data center projects. Three things change first.
01
Speed to power
Teams design, build, and commission faster, with less labor and material on site. One cabinet replaces a PDU and two RPPs, so there is less to specify, install and test.
02
Usable capacity
A mechanical breaker trips inside a band of uncertainty, so engineers pad around it. Ours trips on a precise line that software can move, so the megawatts you already paid for become usable.
03
Floor space back
Rapid protection means systems do not have to be overbuilt for let-through energy. Rooms of legacy gear become compact solid-state blocks, leaving more room for GPUs, so revenue expands before the building does.
We are working to transform the utility grid, the backbone that underpins every other part of our society.

Same compute, less space

40% less power distribution floor for the same 100 MW

Legacy AC protection has to be derated, so a 1 MW circuit only ever delivers 800 kW. You buy the megawatts, then build extra rows to carry them.

Legacy AC protection is derated, so each 1 MW circuit only delivers 800 kW. 100 MW needs 125 rows.
Merge4 meets NEC 100% capacity rating, so there is no derating and every circuit delivers its full rating.

FAQ

The questions operators ask first

What does Merge4 make, and can I order it now?
Two standalone products and one solution package, all on one platform: the DC Solid-State PM50 module, the DC Solid-State PDU, which holds up to seven PM50s, and the DC Intelligent Power Row, a complete power train from source to server rack. All three run Merge4 physical AI firmware. We are taking orders now for all three, with lead times well within those of conventional power equipment.
Is this hardware, or software on top of legacy gear?
Neither, and that is the point. Merge4 is an AI-native design: patented, pure solid-state hardware built from first principles so intelligence is native to the platform rather than bolted on. Physical AI in the power layer is only possible on solid state, because electromechanical hardware cannot sense, learn, or act fast enough.
My facility is AC. Is a DC row relevant to me?
Yes. Your facility is already more DC than you think: the UPS output is DC and your servers are DC. Merge4 plugs into that existing layer. An upgrade or expansion row turns a legacy AC data center into a hybrid facility without ripping out what works, while new builds go DC-to-DC from day one.
Is this tied to a specific GPU vendor or rack architecture?
No. Merge4 manages the DC power feeding the rack and never touches GPU logic, so it is vendor-agnostic by design. It is built for both high-voltage DC architectures the industry is adopting, and denser next-generation racks only make the platform more valuable.
What happens if it breaks?
You swap the module and the row stays live. Hot-swappable PM50 modules let a technician service one unit without taking down the loads around it. That same modularity is how you adopt Merge4 in the first place: start with a single module or an expansion row alongside your existing AC infrastructure, keep what already works, and scale on your timeline rather than ours. Nobody should have to bet a site to try something new.
