Mivium Raises $4.2M Seed for Wide-Bandgap Semiconductor Materials
Mivium Secures $4.2M Seed Round
Mivium, an advanced materials company based in Fremont, California, has raised $4.2 million in seed funding.
What the Company Does
Founded in 2022, Mivium develops high-purity wide-bandgap semiconductor materials. Its work begins with phase-pure submicron gallium nitride (GaN) powder and moves toward GaN and aluminum gallium nitride (AlGaN) substrates.
The company's patented production process is designed to make GaN scalable and cost-effective without the toxic byproducts of conventional manufacturing. Its target markets include power electronics, AI data centers, electric vehicles, aerospace, and telecommunications.
Round Details
- Round type: Seed
- Amount raised: $4,200,000 USD
- Funding date: October 23, 2026
- Location: Fremont, California
- Founded: 2022
Why It Matters for Acquisition Watchers
Mivium sits at the materials layer of the wide-bandgap semiconductor supply chain — an area of growing strategic interest given demand across power electronics, AI data centers, electric vehicles, aerospace, and telecommunications. The company's focus on phase-pure submicron GaN powder and a path toward GaN and AlGaN substrates positions it in a technically demanding segment where manufacturing scalability and cost are central challenges.
Its patented process, which the company says is designed to avoid the toxic byproducts of conventional manufacturing, is a differentiator worth tracking as the company moves from powder toward substrates. A $4.2 million seed round is an early-stage financing, indicating the company is at the beginning of commercial scaling.
Summary
Mivium, a Fremont, California-based advanced materials company founded in 2022, has raised $4.2 million in seed funding. The company develops high-purity wide-bandgap semiconductor materials, starting with phase-pure submicron GaN powder and moving toward GaN and AlGaN substrates, targeting power electronics, AI data centers, electric vehicles, aerospace, and telecommunications.
