Hacoco is a private collector intelligence system: rigorous enough to support decision-making, restrained enough to avoid overstating certainty, and structured around evidence the collector can inspect.
Artist name canonicalization against aliases, spellings, and market history.
Public auction records and normalized artwork metadata across major houses.
Filtered by medium, scale, recency, and source quality.
Price normalization with risk assessment, confidence scoring, and sale routing.
Hacoco is built around public auction records, artist identity data, realized sale outcomes, and normalized artwork metadata. Transaction records are treated as evidence only when the source, sale date, realized price, medium, and dimensions can be interpreted with sufficient clarity.
Before pricing begins, the artist name is resolved against canonical names, alias variations, spelling differences, and market history. This prevents a collector-facing valuation from starting with a fragile text match.
Value is set by the artist's own recent auction results, the way an auction specialist prices a lot. Up to 20 sales are selected and weighted by medium match, size, recency, period of execution, and source quality. Records that differ materially from the submitted work are down-weighted or set aside.
Price does not rise in step with area: in our data a canvas twice the size fetches about 1.5 times as much. Each comparable is restated to the submitted work's size along that curve and to today's market level, outliers are excluded, and the weighted median of the adjusted prices sets the value. The range follows how closely the evidence agrees, at the widths auction houses publish.
Public auction realization is modelled separately from private market value. Auction can create competitive tension, but it also introduces reserve, timing, venue, and public failure risk. Private sale may protect discretion and route control.
Confidence reflects evidence depth, comparable consistency, market liquidity, and the quality of artwork details supplied. Sparse records, seed-only identities, unusual media, high-value estimates, and private-sale recommendations may trigger advisory-led pricing. Hacoco outputs are market-intelligence estimates, not guarantees, formal appraisals, authentication opinions, or offers to purchase.
