Quantitative infrastructure for the art market.
We apply the analytical rigor expected of public-market research to the art market — without the opacity, bespoke fees, or implied advisory relationship of traditional art-market consultancies.
What we do
We aggregate publicly disclosed auction records from the world's primary auction houses, normalize them into a research-grade panel, and run a cascade of econometric and probabilistic models to produce per-artist price indices, risk metrics, comparables, and forward forecasts. The flagship product is a probabilistic auction guarantee pricing model: given a lot, what guarantee maximizes expected house P&L while keeping P(loss) below an underwriter-chosen ceiling.
Who it is for
Who builds it
A small team. Methods on one side, infrastructure on the other.
Builds the platform's quantitative methods, data pipelines, modeling infrastructure, frontend, and public API. Every model, migration, and methodology section on this site to date is his work.
What we are not
White River is not a registered investment advisor, art advisory firm, or appraiser. Outputs are model estimates intended to inform professional judgment, not replace it. See our methodology page for the full caveats and validation discipline behind every number on this site.
