Casimir

What Casimir does

Casimir is a Houston, Texas-based private quantum energy startup founded in 2026 that is developing the MicroSparc, described as the world's first quantum vacuum energy harvesting chip. The MicroSparc is a 5mm square semiconductor device that generates continuous electrical power by harvesting energy from quantum vacuum fields, producing 1.5 volts at 25 microamps with no degradation cycle. The company targets ultra-low-power electronics applications where battery replacement is costly, impractical, or impossible — a market it estimates at $10 billion initially and over $67 billion broadly. Casimir positions itself as a single-product hardware company addressing the maintenance burden and lifecycle cost of batteries in remote, inaccessible, or high-cost-to-service deployments.

The company launched in May 2026 with a $12 million oversubscribed seed financing round, exceeding its original $8 million target. The round was led by Scout Ventures, with participation from Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Draper Associates (Tim Draper). Casimir has stated it will use the capital to optimize chip technology and accelerate commercialization, with commercial availability of the MicroSparc expected by 2028. The investor mix is heavily skewed toward deep-tech and early-stage venture firms, which is consistent with a hardware technology requiring multi-year R&D prior to commercial release.

Casimir's go-to-market is expected to follow an enterprise B2B sales motion targeting ultra-low-power electronics manufacturers, OEM partners, and IoT device companies as design-in customers. The company has not yet disclosed pricing, distribution channels, marketing channels, named customers, patents, trademarks, regulatory actions, leadership hires, or manufacturing partnerships. With no revenue, no commercial product, and no disclosed operational headcount, Casimir is at the earliest pre-commercial stage of its development cycle, and its commercial thesis remains unvalidated pending chip sampling, customer pilot activity, and the 2028 commercial release milestone.

Direct peers

• EnOcean: EnOcean pioneered battery-less wireless sensors using energy harvesting from motion, light, and temperature differentials. Its self-powered sensor technology serves building automation and industrial IoT — overlapping deeply with Casimir's target applications.
• Atmosic Technologies: Atmosic designs Bluetooth SoCs with integrated energy harvesting for IoT devices, directly competing with Casimir's vision of battery-free ultra-low-power electronics. Its ATM-series chips harvest ambient RF, solar, and thermal energy, mirroring MicroSparc's value proposition of eliminating battery replacement.
• NOWI Energy: NOWI develops energy harvesting PMICs and modules specifically designed to power IoT devices from ambient energy sources. It targets the same battery-replacement pain point that MicroSparc addresses, with comparable form-factor and power-output considerations.
• e-peas: e-peas builds power management ICs (PMICs) purpose-built for energy harvesting in IoT and remote sensor applications. Its AEM and EDL series harvest energy from solar, RF, vibration, and thermal sources — the exact ultra-low-power electronics market Casimir targets with MicroSparc.

Emerging players

• Ossia: Ossia develops Cota wireless power technology that delivers energy over RF to multiple devices at a distance. Like Casimir, it pursues the vision of continuous, wire-free power for low-power electronics, though via a different (transmitted RF) mechanism.
• Wi-Charge: Wi-Charge delivers long-range wireless power over infrared to small electronic devices, eliminating the need for batteries or charging. While the mechanism (directed RF/optical) differs from Casimir's quantum vacuum approach, the end goal of battery-free electronics makes it a relevant adjacent peer.

Broad incumbents

• Texas Instruments: TI's broad portfolio of ultra-low-power MCUs, PMICs, and energy-harvesting ICs serves virtually every segment Casimir targets. While TI does not compete in quantum vacuum harvesting, its scale, OEM relationships, and roadmap could overshadow any niche entrant.
• STMicroelectronics: ST offers an extensive portfolio of low-power STM32 microcontrollers, PMICs, and energy-harvesting solutions for IoT and industrial sensors. Its scale and OEM design-in presence represent both the competitive benchmark and a potential partnership/acquisition target for Casimir.
• Analog Devices: Analog Devices manufactures power management ICs, sensors, and signal conditioning products extensively used in ultra-low-power IoT applications. Its energy-harvesting-compatible components and broad industrial customer base make it a relevant incumbent comparable.
• Infineon Technologies: Infineon's low-power semiconductors, including its PSoC family and energy-harvesting PMICs, target industrial IoT and consumer ultra-low-power applications. Its broad portfolio and automotive/industrial footprint position it as a strategic comparable for Casimir's market.
