Rebulk

Rebulk is a Y Combinator-backed company that accurately measure and monitor bulk inventory. Based in Olathe, USA, the company participated in the Summer 2025 batch of Y Combinator.

Rebulk accurately measures and monitors bulk inventory like piles of feed, sand, and other assets that do not fit into boxes and barcodes using cameras, LiDAR, and computer vision.

Most bulk inventory is still managed with rough estimates, manual checks, delayed updates, and too much guesswork. Because it lives in piles, bays, yards, and truck beds instead of boxes with barcodes, it is much harder to track accurately.

Rebulk was part of Y Combinator's Summer 2025 cohort, has a team of approximately 3 employees, and is actively operating.
