Artsignal was built by Sam Glatman after he started using a spreadsheet to organize auction results and track the market.

Artsignal delivers a decision-ready intelligence for every object: a proposed value, selected comparables, supporting evidence, market nuance, cultural context, confidence indicators, and risk flags. Across a collection, that same intelligence aggregates into a portfolio view surfacing trends, concentration, and risk at scale. Teams can review and refine, helping organizations extend the same level of rigor across far more objects, without compromising judgment, auditability, or control. Every conclusion remains traceable, verifiable, and reusable. Backed by Christie's Ventures and developed alongside curators, auctioneers, and advisors, With team members across London, New York, and Hong Kong, we work closely with the art market's major centers.
