# Rebulk

> Rebulk is a Y Combinator (S25) startup that measures and monitors bulk inventory - feed, sand, grain, logs, biomass and other materials that never fit into boxes or barcodes. Using fixed cameras, drones, LiDAR and computer vision, Rebulk stitches 2D imagery into 3D volumetric models to give industrial teams precise, repeatable volume and weight data instead of rough estimates and manual checks. Founded in Olathe, Kansas by Warren Wang and Cole Robertson, the company pivoted from video transcription (as dScribe AI) to bulk inventory tracking and now runs pilots with partners including Cargill and Charm Industrial.

- **Founded:** 2024
- **Headquarters:** Olathe, Kansas, United States
- **Founders:** Warren Wang (Co-Founder and CEO), Cole Robertson (Co-Founder and CTO)
- **Team size:** 3-7
- **Products:** Bulk Inventory Platform, 3D Volumetric Reconstruction, Packing Factor Estimation, Time-series Inventory Tracking
- **Notable:** Accepted into Y Combinator's Summer 2025 (S25) batch, Named to Startland News' Kansas City Startups to Watch (2026), Selected for the 2026 LaunchKC funding cohort

## Products & services

- **Bulk Inventory Platform** — An integrated hardware-software platform that measures and monitors bulk inventory using fixed cameras for indoor piles and drones for outdoor sites, producing 3D reconstructions with precise volume and weight data.
- **3D Volumetric Reconstruction** — Stitches overlapping 2D imagery from drones, fixed stations and phones into a 3D volumetric model, identifying the underlying ground surface to account for sloped terrain.
- **Packing Factor Estimation** — Computer vision analyzes side-view imagery to estimate void fractions inside a pile, converting bulk volume into estimated usable material volume.
- **Time-series Inventory Tracking** — Geotagged, repeatable records that track pile growth and depletion over time to improve forecasting and logistics, functioning in remote, low-connectivity areas.
