# Picarro

> Picarro builds laser-based gas analyzers that detect molecules at parts-per-billion (and better) using its patented Cavity Ring-Down Spectroscopy (CRDS). Its instruments are deployed by utilities, semiconductor fabs, biopharma cleanrooms, and climate scientists across roughly 90 countries to find methane leaks, measure greenhouse gases, monitor hazardous air pollutants, and track water isotopes.

- **Founded:** 1998
- **Headquarters:** Santa Clara, California, United States
- **Founders:** Barbara Paldus (Co-founder), Aaron Kachuck (Co-founder)
- **Team size:** ~200 employees
