AI Clearing
AI Clearing is an Austin- and Warsaw-based construction technology company that turns drone imagery and site data into automated progress tracking, quality control, and field intelligence for large infrastructure projects. Its AI-native platform ingests drone flights, CAD/BIM designs, schedules, and mobile field data into a single source of truth, delivering analyzed progress reports typically within hours rather than weeks. Serving contractors, asset owners, and lenders on utility-scale solar, energy transmission, roads, railways, and earthworks, the company raised a $14M Series A in 2023 and was the first technology firm in the world to certify its AI management system against ISO 42001.
