What they do

Problem

Bulk inventory stored in piles and yards is difficult to measure and track accurately, leading to shrink, stockouts, and poor planning.

Solution

Rebulk uses cameras, LiDAR, and computer vision to accurately measure and continuously monitor bulk inventory volumes.

Who it's for

Operations teams at companies handling bulk materials (e.g., agriculture, feed suppliers, construction materials) that need accurate on-site inventory tracking.
