Casimir Raises $12M in Series B Funding

The company plans to use the funding to improve chip performance and accelerate development of its MicroSparc chip, with a commercial launch targeted for 2028.

Casimir’s MicroSparc chip is only 5mm by 5mm and is designed to generate 1.5 volts at 25 microamps, offering performance similar to a small rechargeable battery but without degradation or the need for replacement. The company is initially targeting ultra-low-power devices, such as tire pressure monitoring systems, embedded sensors, wearables, and other electronics, where battery changes are difficult or expensive. This market is currently valued at nearly $10 billion.

Casimir is designing its technology to support a wide range of power needs. While the company is first focusing on IoT and low-power devices, its long-term plans include consumer electronics, electric vehicles, and larger energy systems that could power homes and commercial buildings, representing a market worth more than $67 billion.

As artificial intelligence increases demand for constant, low latency computing, Casimir’s battery-free technology could support always on memory, edge computing devices, and autonomous systems across many industries.

Casimir’s technology was developed at the Limitless Space Institute (LSI), a nonprofit focused on advancing interstellar travel, founded by Kam Ghaffarian, who is also known for companies such as X-energy, Intuitive Machines, Axiom Space, and Quantum Space. Dr. White served as LSI’s Director of Advanced Research and Development, where Casimir’s technology originated. Dr. Ghaffarian remains involved with Casimir as an investor and board member.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” said Brad Harrison, Founder and Managing Partner at Scout Ventures. “This is based on 100 years of science, and we’re finally approaching a commercial product. Sonny’s ability to pull together components from different research domains and engineer them into working hardware is remarkable. We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” said Dr. Harold “Sonny” White, Founder and CEO of Casimir. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”

About Casimir

Founded in 2023, by Harold White, Casimir is developing semiconductor chips that generate continuous power using quantum vacuum physics, without batteries, charging or power cords. Its technology is based on decades of quantum physics research, DARPA funded nanofabrication work, and peer-reviewed studies. Casimir is headquartered in Houston and develops its technology in the United States.
