About RATART Auctions

RATART Auctions is a curated secondary-market auction house connecting collectors with exceptional contemporary and modern artworks. Based in Switzerland, we operate a lean, selective platform where every artwork is reviewed before it reaches auction.

Our model is built around continuous themed auctions rather than traditional calendar-bound sales. Artworks are grouped into curated themes — providing context and narrative for collectors while giving consignors meaningful exposure.

What Makes Us Different

• Curated, not open-market. Every submission goes through curatorial review. We value quality and fit over volume.
• Transparent bidding. Blind bidding with verified payment holds ensures serious intent and a fair process for both buyers and consignors.
• Valuation expertise. Our team provides independent valuation guidance, drawing on deep art-market knowledge to set credible reserves and estimates.
• Multi-currency support. Prices display in CHF, EUR, GBP, and USD — real-time converted — so collectors bid in the currency they know.

For Collectors

Discover artworks through thematic curation, not endless scrolling. Register, verify progressively as you bid, and bid with confidence knowing payment holds back every bid. Learn more about buying.

For Consignors

Submit your works for independent valuation and placement in themed auctions. Our six-week consignment window gives artworks focused exposure, and payouts are made promptly after delivery confirmation. Learn more about consigning.
