What Rebulk does

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. When teams do not know what is actually on site, it leads to shrink, stockouts, bad planning, and unnecessary fire drills. We’ve lived this problem, and we know how to solve it. Warren saw it firsthand as a Product Manager at Milk Moovement, a $20M Series A AgTech startup, working closely with feed suppliers and farm managers. Cole was engineer #3 at Tropic, scaling it from seed to Series B, and later led engineering at an AI startup. We’ve built an integrated hardware and software platform and is working with one of the largest agricultural company in North America and Charm Industrial. As industries demand real-time visibility into the physical world, RebuIk is positioned to become the operating system for bulk assets from inventory tracking to procurement and logistics.

Accurately measure and monitor bulk inventory

What is your company going to make? Please describe your product and what it does or will do.

We've built a hardware and software platform that uses cameras, LiDAR, and computer vision to measure and monitor bulk inventory like feed, sand, and other loose assets. It solves the problem of inaccurate estimates and delays common in managing inventory that can't be tracked with barcodes because it sits in piles or open yards. Our system gives real-time visibility and precise volume measurements to reduce shrink, stockouts, and firefighting in supply chains that handle bulk materials.

Where do you live now, and where would the company be based after YC?

We live in Olathe, KS, and plan to base the company here after YC.

Explain your decision regarding location.

Olathe is central to the agricultural supply chains we serve and where we have industry connections. It's where we can remain close to our early customers and operate efficiently.
