Veliu

Veliu is a circular economy platform that applies artificial intelligence to the resale of pre-owned goods. Its product-centric platform connects consumers, retailers and professional used-goods buyers, with the aim of recovering value from second-hand items and helping brands sell more sustainably. The company is headquartered in Milan, Italy, and reports rapid scaling across Europe, with more than 9,000 businesses using the platform.

The company's technical work centres on AI and knowledge graphs. Veliu builds agent-readable copies of brand product catalogues, structured so that they can be read and purchased by AI shopping agents such as ChatGPT, Gemini, Perplexity and Claude. This involves reading each product as an AI agent would, identifying missing attributes, incorporating real reviews and assembling the results into a knowledge graph that is updated as product information changes.

Alongside this, Veliu provides analytics on how brand catalogues are read, cited and crawled by major AI engines, giving visibility into a brand's share of AI answers and its ranking relative to competitors. Catalogue enrichment and sync endpoints keep product data current across integrations. The work sits at the intersection of e-commerce catalogue optimisation, resale technology and agentic commerce, across retail, second-hand goods and sustainable commerce verticals.
