Problem
Resellers, auction houses, and insurers lack reliable, market-backed pricing data for second-hand goods, often relying on scraped listings or manual appraisals that are slow, inconsistent, and difficult to defend. This makes it hard to set accurate prices, win consignments, issue credible valuations, or process claims efficiently.
Solution
Circulaire provides a unified platform for valuing, certifying, and selling pre-owned goods. Its pricing intelligence API and embeddable widget deliver instant, AI-driven valuations based on image and text identification across six asset categories. The platform also generates white-label valuation certificates with documented comparables and confidence levels, and includes a full white-label auction system with AI-assisted cataloguing, Stripe payments, and Nordic VAT compliance. All three products are powered by a shared data flywheel: auction sales feed a proprietary resale pricing dataset, which sharpens valuations and makes certificates more credible.
Target Audience
Primary customers are resellers and consignment shops, auction houses, insurers and appraisal firms, and developers or platforms that need integrated second-hand valuation capabilities.
