The most important part of a new semiconductor is the part you never see. It’s the substrate, the crystalline foundation upon which everything else is built. For decades, that foundation has been silicon. But in a Fremont lab, a two-year-old company named Mivium is betting the next foundation will be made from gallium nitride, and they want to sell it by the particle.
Mivium is an early-stage material science company with a focus on gallium nitride (GaN) and other wide bandgap materials [Mivium]. Its business model is straightforward: develop and commercialize high-quality GaN particles and substrates, then sell them to OEMs and device makers across power electronics, RF communications, and medical imaging [SEC, April 2024]. The company’s recent $5 million funding round, completed in June 2024, is aimed at expanding manufacturing and product development [Yahoo Finance, June 2024]. For CEO and co-founder Eric Tsai, it’s a bet on moving the industry’s building blocks upstream, from finished chips to the raw, engineered material they’re made of.
The substrate as a strategic wedge
Silicon’s reign is facing physical limits, especially in applications demanding high power, high frequency, or extreme efficiency. Wide bandgap materials like GaN offer a path forward, enabling devices that are smaller, faster, and waste less energy as heat. The challenge has been producing these materials at a quality and scale that makes economic sense for mass adoption. Mivium’s stated wedge is a patented process it claims can deliver that scale, producing GaN particles and substrates with the consistency needed for commercial fabrication [Mivium].
By focusing on the material itself, Mivium is attempting to insert itself into the value chain at its most fundamental point. Its potential customers are the companies designing the next generation of power converters for data centers, 5G/6G radio hardware, lidar sensors, and medical imaging equipment [Yahoo Finance, June 2024]. If the material performs as promised, it becomes a hidden enabler, a commodity with proprietary margins.
A founder with supply chain scars
The team building this material foundation brings a specific kind of experience. Eric Tsai’s background is a mix of high-volume manufacturing and startup hustle. He previously served as a Staff Engineering Program Manager at Tesla Energy, focusing on industrial storage, a role that would have involved navigating complex supply chains for critical hardware [LinkedIn]. Before that, he held business development roles at Applied Materials, a giant in semiconductor manufacturing equipment, and was a co-founder at Asteroom [LinkedIn]. This path suggests a founder who has seen both the scale of a Fortune 100 operation and the grind of building something from zero.
While the technical leadership is less detailed in public filings, the company notes a Dr. Deshpandey leads technology execution, with over 40 years of experience in semiconductors and materials science [Mivium]. The pairing aims to bridge the gap between lab-grade innovation and industrial-grade production.
Funding through dual tracks
Mivium’s capitalization strategy is as notable as its technology. The company is pursuing funding on two parallel tracks. The first is a traditional seed round: the $5 million closed in June 2024, with investors including James Altucher and Asymmetric Ventures [Yahoo Finance, June 2024]. The second is an ongoing Regulation Crowdfunding (Reg CF) public offering, where Mivium is selling shares of common stock at $0.10 per share, with a maximum target of $5 million [SEC, April 2024]. This dual approach diversifies its investor base, mixing institutional capital with a broader, public pool.
The table below outlines the company's current funding structure.
| Round Type | Date | Amount | Lead Investor | Offering Price |
|---|---|---|---|---|
| Seed Round | Jun 2024 | $5,000,000 | Unknown | N/A |
| Reg CF Offering | Filed Apr 2024 | Up to $5,000,000 (estimated) | Public (via Equifund) | $0.10 per share |
The material reality check
For all the promise of GaN, the path for a new materials supplier is steep. Mivium operates in a field with established incumbents and deep technical moats. The company’s public disclosures, while confident in its patented platform, do not yet name design-win partners or publicly disclosed customers. In materials science, a patented process is only as valuable as the yields and performance it delivers at volume. The risks here are not about vision, but about execution at the atomic level.
- The scaling cliff. Moving from lab samples to production-ready, wafer-scale material is a notorious valley of death for hardware startups. Mivium’s $5 million war chest is meaningful, but it’s a modest sum for the capital-intensive work of scaling a materials fabrication process.
- The qualification queue. Semiconductor customers have long, rigorous qualification cycles. Before a chipmaker bets its billion-dollar product line on a new substrate, it will test that material for months or years. Mivium’s commercial traction will be measured not in quarterly sales, but in the length of its customer qualification list.
- The incumbent response. Larger materials companies are also investing heavily in GaN. Mivium’s success depends on its process being not just good, but significantly better or more economical than the alternatives already in development.
The company’s most plausible answer to these challenges is its focus. By not trying to build finished devices, it avoids several layers of complexity and competition. Its job is to make a better, cheaper brick and convince the world’ best architects to build with it.
The efficiency equation
The ultimate case for GaN, and for companies like Mivium, is written in joules and dollars. Wide bandgap materials can significantly reduce energy loss in power conversion. In a data center, for instance, shaving a few percentage points off power conversion losses translates directly into lower electricity bills and reduced cooling needs. For a rough sense of scale, if GaN-based power electronics improved efficiency by just 2% across a large data center’s power load, the annual savings could run into the millions. That’s the kind of math that gets the attention of procurement departments, and it’s the economic lever Mivium must pull.
To succeed, Mivium must do more than make a promising material. It must out-execute the materials divisions of entrenched giants who already have the customer relationships and the billion-dollar fabs. Its bet is that a focused, agile startup can move faster on the next foundational technology. For now, the company is building its foundation, one gallium nitride particle at a time.
