Across agriculture, mining, and construction, billion-dollar supply chains still run on a phone call and a guess. Someone walks outside, eyeballs a pile of feed, and tells the truck dispatcher what they think is left. They’re wrong by 30 to 50 percent — and that error ripples into spoiled inventory, empty feedlots, and hundreds of thousands of dollars in losses.

Warren Wang and his co-founder Cole built Rebulk to fix that. Using lidar, computer vision, and edge-connected hardware, they’re giving operators real-time inventory visibility for bulk materials that have never fit inside a barcode or a box. Their first proof of concept? Packing peanuts from Office Depot dumped on the ground.

In this episode, host Kevin McGinnis sits down with Warren to trace the arc from a failed social media transcription startup to a Y Combinator-backed company with Cargill as a pilot customer — all while raising their pre-seed entirely from Kansas City investors. Warren opens up about the identity crisis that nearly derailed the pivot, what it took to build trust inside a tech-skeptical industry, and why he and Cole chose to come back to the Midwest instead of staying in San Francisco.

Recorded on the same day Warren became a U.S. citizen, this conversation is about more than supply chain software. It’s about conviction, belonging, and building something generational.
