Value proposition
Reduces textile waste and costs by identifying defects during the production process, rather than after, enhancing sustainability and operational efficiency.
Products and solutions
Smartex CORE™ System (Hardware and software for real-time fabric inspection), Data Analytics Platform (Provides insights on machine performance and defect trends)
Unique value
A first-mover in combining edge-AI and computer vision directly onto textile machinery for real-time defect detection, a sector historically underserved by advanced automation due to the complexity of materials.
Target customer
Textile manufacturers, specifically factories with circular knitting machines and other industrial fabric production lines.
Industries served
Textile Manufacturing, Apparel
Technology advantage
Proprietary deep learning models trained specifically for fabric inspection, robust hardware designed for harsh factory environments, and a seamless plug-and-play integration with existing machinery.
How they differentiate
Smartex provides real-time, in-line defect *prevention* directly on knitting machines, whereas competitors like Uster often focus on post-production quality control (lab testing) and Inspectorio focuses more broadly on supply chain quality assurance rather than real-time production monitoring.
Main competitors
Uster Technologies, Inspectorio
Key partnerships
Lightspeed Venture Partners, Tony Fadell's Build Collective, H&M Group, Fashion for Good, Leading textile manufacturers in Europe and America
