Led · Series A · Dec 2022
LongPath builds proprietary, laser‑based sensing nodes that deliver precise quantification and localization of methane emissions and real‑time data to customers via a dashboard. Its solution supports LDAR, OOOO, OGMP and other regulated programs to help operators reduce emissions and meet compliance. The company traces its technology to research at the University of Colorado Boulder and NIST and emphasizes commercialization of lab‑developed quantum optics. LongPath says it will deploy sensing nodes across all U.S. production basins to enable rapid leak detection and mitigation. Management highlights job creation, operator partnerships through the PathFinder Program, and broader plans to commercialize globally. The company recently closed a major DOE loan that will finance nationwide deployment. LongPath Technologies develops patented systems to continuously monitor and quantify methane emissions, offering flexible coverage from a single site up to 20+ sites across 20 square miles. Its platform delivers real-time, actionable insights with equipment-level localization and quantification vetted through a peer-reviewed, blind-tested methodology. Systems allow operators to tailor measurement frequency, quantification rigor, detection thresholds, and alert modalities to match facility types, operational goals, and budgets. Led by CEO Ian Dickinson and based in Boulder, CO, the company targets energy and industrial infrastructure customers. LongPath plans to scale deployments across existing and new customers and markets and further develop its technology for use across oil and gas, waste management, mining, and urban monitoring sectors. The company recently completed a $22M Series A to fund those expansion and product-development efforts.
