Casimir Announces $12 Million Seed Financing

Gunderson Dettmer represented Casimir in its $12 million oversubscribed seed financing. The round was led by Scout Ventures with participation from Lavrock Ventures, Cottonwood Technology, Capital Factory, and American Deep Tech.

Casimir is the world’s first quantum vacuum energy company, developing semiconductor chips designed to generate persistent power using the physics of the quantum vacuum, no batteries, cords, or charging required. The funding will accelerate chip performance optimization, targeting commercial availability of the company's first-generation MicroSparc chip by 2028, positioning Casimir to disrupt the ultra-low-power electronics sector.

“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, in the announcement of the transaction. “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.”

The Gunderson deal team included Anand Mehta, Joe McGinley, Ben Cukerbaum, Anthony Farnesi, and Ben Lezin.
