Our Team
Alex Hilger, Co-Founder & CEO
Alex brings deep expertise in 3D scanning and LiDAR technology to Space Grid AI. While working on the New Glenn rocket program at Blue Origin, Alex lived through the “hair on fire” problem of managing constantly shifting industrial spaces—an experience that inspired him to tackle this challenge head-on. Alex and co-founder Heath Attia first collaborated at AEye, an automotive LiDAR company, where they honed their skills in 3D mapping and problem-solving. With a degree in Mechanical Engineering from the University of Maryland, Alex combines hands-on experience and visionary thinking to revolutionize space planning for dynamic industries.
Heath Attia, C0-Founder & CTO
Heath Attia is a 3D mapping and SLAM (Simultaneous Localization and Mapping) expert with extensive experience in LiDAR technology and perception systems. Over his career, Heath has developed groundbreaking solutions at industry leaders like Waymo, where he worked on perception hardware for autonomous vehicles, and AEye, where he first collaborated with Alex to tackle complex spatial challenges. At Transrobotics, he designed advanced digital radar systems for autonomous platforms, and his work with Kudan further cemented his expertise in SLAM technologies. Heath’s deep technical knowledge, combined with a proven ability to integrate innovative spatial solutions, drives the cutting-edge capabilities of Space Grid AI’s platform.
