PRENAV

PRENAV is a drone technology company that provides near-ground autonomy solutions for drones, enabling automated flight within centimeters of structures for close inspection by non-expert pilots. The system uses a ground-based robot to scan and map an area including vertical surfaces, creating a precise 3D model that guides the drone autonomously along inspection paths. PRENAV technology addresses the challenge of inspecting complex infrastructure such as cell towers, wind turbines, bridges, and industrial facilities where manual drone piloting is difficult and dangerous. The platform combines hardware and software to achieve centimeter-level positioning accuracy, capturing high-resolution imagery and data that can be used for structural analysis, defect detection, and maintenance planning. Founded in 2013 and headquartered in Redwood City, California, PRENAV has raised approximately $7.7 million in seed funding from investors including Pear VC, NTT Docomo Ventures, Crosslink Capital, and WI Harper Group.
