For decades, silicon has been the backbone of the modern electronics industry. From smartphones and laptops to electric vehicles and data centers, nearly every advanced technology we rely on today is powered by silicon-based semiconductors.

But that era is coming to an end.

As demand for computing power explodes—driven by artificial intelligence, high-speed telecommunications, and electrification—silicon is hitting its physical and performance limits. It's running too hot, drawing too much power, and simply can’t keep up with the demands of next-generation systems.

The world needs a better material. And increasingly, experts believe that material is gallium nitride.

GaN offers performance advantages silicon simply can’t match. It conducts electricity more efficiently, handles higher voltages, and operates at significantly higher temperatures. It’s already being adopted in applications ranging from AI data centers and EV chargers to military-grade radar and aerospace systems.

But there’s one big problem: China currently controls 98% of the global GaN supply—and they’ve just imposed new export restrictions. That move has sent shockwaves through the global tech and defense sectors, triggering fears of a new chokepoint in the global semiconductor supply chain.

An American Solution

In the face of this growing crisis, one American company is stepping up with a solution.

Meet Mivium.

Headquartered in Silicon Valley, Mivium is a material science startup developing a proprietary method for producing ultra-high purity GaN—cleanly, efficiently, and at scale. Unlike traditional GaN production processes that rely on toxic chemicals and generate significant waste, Mivium’s patented approach uses no hazardous solvents and drastically reduces water consumption.

This innovation doesn’t just make GaN production more sustainable—it makes it viable on U.S. soil, a critical advantage as the global semiconductor industry races to re-shore supply chains and reduce dependency on foreign adversaries. Best yet, anyone can invest in this pre-IPO opportunity at a critical time for the U.S. tech sector. 

Backed by a team of veterans from Intel, Lam Research, and Applied Materials, Mivium has plans underway to build their first facility in Nevada’s booming tech corridor—home to companies like Apple, Tesla, and Google. They’re well-positioned to become a strategic supplier in what’s projected to be a $26.8 billion GaN market by 2032.

It’s rare to see a materials breakthrough that aligns so directly with both market opportunity and national security interests. But Mivium is doing just that—offering investors a unique chance to get in early on a company solving one of the most urgent problems in advanced technology today.
