Circulaire

Circulaire is a Swedish technology firm that provides valuation infrastructure for the resale economy through three integrated products: pricing intelligence, white-label certificates, and full auction systems. The company leverages real transaction data from its own auctions to power accurate market valuations across watches, handbags, sneakers, trading cards, and art.

• Products: Offers a pricing API with embeddable widgets, branded PDF valuation certificates, and a complete auction platform featuring AI cataloguing and payment processing.
• Industries: Serves resellers, consignment shops, auction houses, insurers, appraisers, and developers requiring EU data residency.
• Innovation: Utilizes a proprietary flywheel where settled auction transactions continuously refine pricing models to increase certificate credibility over time.

Circulaire triangulates valuations across leading global resale marketplaces while documenting confidence levels and regional pricing normalisation for every result.
