NevadaNano
NevadaNano (Nevada Nanotech Systems, Inc.) is a Sparks, Nevada company that builds MEMS gas sensors and hardware-enabled SaaS for detecting flammable gases and quantifying methane and other emissions. Its patented Molecular Property Spectrometer (MPS) measures the thermodynamic properties of a gas mixture instead of relying on chemical reactions, delivering multi-gas detection with a 15-year life and no field calibration. The MPS platform powers flammable, refrigerant, methane, and hydrogen sensors, and underpins MethaneTrack, a continuous methane-monitoring system used to cut LDAR costs and meet OGMP 2.0 reporting requirements.
Calyx
Calyx (formerly BioInspira) is a Berkeley-based agtech company that combines AI-powered computer vision with proprietary phage-based biosensors to help poultry farmers monitor flock weight, environmental conditions, and gas levels in real time. Founded in 2014 by UC Berkeley bioengineering alumni, the company's platform integrates overhead cameras, multi-gas sensors, and cloud analytics to give broiler producers continuous, data-driven visibility into flock health and harvest timing — with 98.4% accuracy in predicting chicken weight across more than 17 million validated birds.
