Overview
Providing asset intelligence for the world’s leading cultural and financial institutions.
At Ad Restitūtio, we provide comprehensive intelligence to help insurers and institutions reclaim stolen heritage, transforming dormant write-offs into high-yield recoveries. While we maintain a vigilant, automated watch over all major and secondary global auctions, our true edge lies in seeing the hidden digital landscape. We proactively analyze the vast pool of publicly accessible visual data, spanning non-traditional marketplaces, social media, real estate listings, and news articles. Our specialized deep AI identifies missing masterpieces tucked away in the backgrounds of everyday photos, ensuring that no stone is left unturned, from the auction block to the digital backdrop.

Results
Recent Finds
The examples below were identified from past auctions, after the fact. Ad Restitutio was built to close that gap: alerting museums the moment a work surfaces, not months or years after it has already changed hands.
Portret Arcyksięcia
Portret arcyksięcia Karola Stefana Habsburga by Kazimierz Pochwalski, dated 1912, is listed in Poland’s wartime-loss catalogue as a lost painting. Ad Restitutio identified a possible match on an auction site, but the work’s current whereabouts remain unknown.
Czerkiesi
Czerkiesi by January Suchodolski entered the collection of the National Museum in Warsaw in 1933 and was lost during World War II, probably during the removal or destruction of Warsaw collections in 1944. It resurfaced at Doyle New York in 2006 under a false title, was bought by Alexander Stepanyan of St. Petersburg, and has not been recovered.
Krajobraz Morski
Krajobraz morski by Eduard Hildebrandt is listed in Poland’s wartime-loss catalogue as a missing foreign painting. It was connected to the Toruń museum’s wartime-era painting gallery, and after the war much of that gallery was transferred out to state storage and DESA between 1947 and 1958; the painting’s current location is not confirmed, however an identical painting was identified in a prior auction by AdR.
Dziewczyna z gołębiem
Painted by Antoine Pesne in 1754, Dziewczyna z gołębiem was acquired by the museum in Poznań in 1931 and removed from its collection during World War II. It reappeared in 2010 in Moscow, in the possession of art dealer Alexander Khochinsky, who said he had inherited it from his father, a Soviet World War II veteran; the painting has not been returned and remains disputed.
Niewiasta w kąpieli
Niewiasta w kąpieli by Gerard/Gerrit Dou is listed in Poland’s wartime-loss catalogue as a missing foreign painting. Ad Restitutio identified a possible match on an auction site, but the work’s current whereabouts remain unknown.

Benchmark and validation case study
"Portrait of a Lady"
Stolen from a private collection by the Nazis in 1944
In a landmark 2025 recovery, a masterpiece stolen in 1944 was finally located, not through a database, but through a manual discovery. This case serves as a perfect benchmark for the limits of traditional recovery. Ad Restitūtio used this historical case to validate our engine, testing whether our AI could have bridged that gap in a matter of hours.
Our team ingested the archival representation of the stolen work and ran a retrospective scan, with an alert generated within a few hours. While the painting was unlabelled and appeared in an obscure location, our AI successfully identified the work with 96% confidence.
By generating an automated evidence packet immediately upon detection, our platform proves that we don't just find art—we find it before it can be moved, damaged, or lost to history again. We turn a generation’s worth of searching into a weekend’s worth of processing.
