Greyparrot

Greyparrot builds an AI waste analytics platform that applies computer vision and real-time image analysis to material streams in recycling facilities. Its technology domains span artificial intelligence, computer vision, real-time image analysis, waste classification, material identification, packaging and brand recognition, and data analytics.

The company's product, Greyparrot Analyzer, is a camera-based system deployed on conveyor belts in recycling facilities that captures and analyzes waste streams in real time. It classifies materials across 111 distinct categories and identifies packaging types and brands at industrial scale. In 2025 the system recorded 477 billion detections and analyzed over 52 billion waste objects.

Greyparrot operates from London, UK, with a global presence, serving the waste management, recycling and waste processing sectors. The company has raised $25 million in total: a $2.2m seed round, an $11m Series A and a $12.8m strategic partnership. It was recognized as one of TIME's Best Inventions in 2025.

The company positions itself around the global waste challenge, citing 2.1 billion tons of solid waste produced annually, with the aim of scaling recycling and diverting waste from landfills and incinerators.
