Quantitative infrastructure for art finance.

The public auction record overstates art returns and understates risk — in a known direction, by documented amounts. We statistically correct it, and serve the corrected pricing, risk, and valuation with every model’s uncertainty stated, not buried. Validated out-of-sample — including the lots that failed to sell.

Built for the people who have to put a number in writing — lenders, guarantors, advisors, appraisers, and underwriters — when the raw auction record isn’t evidence enough.
