Casimir

Casimir is an early-stage semiconductor company developing solid-state microchips designed to generate continuous, ultra-low-power electrical output by exploiting engineered asymmetries in Casimir cavities—a well-established quantum mechanical phenomenon. The company is pre-product and pre-revenue, and is currently focused on validating whether this effect can be scaled into a commercially viable power source. The core investment thesis is that ultra-low-power electronics represent one of the few markets where a radically new power architecture could be economically compelling today. Many industrial, medical, and defense systems are constrained by battery lifetime, maintenance costs, and the inability to reliably harvest environmental energy. A continuous, maintenance-free power source—even at microwatt scale—would meaningfully change system design and deployment economics.
