## Executive summary

Ni Yan has established a technical niche by developing utilities exclusively optimized for LiDAR-equipped iPhone Pro and iPad Pro hardware. Their strategy focuses on high-intent professional use cases—such as agricultural inventory and real estate research—rather than broad consumer utility.
