The KMFA Gallery has now become one of the most internationally significant “new generation” galleries. In 2015, the world-renowned art portal Artnet selected it among the 55 best contemporary galleries. The works of the gallery’s artists are found in the great museums of the world. The works of Judit Reigl and Simon Hantai can be found at the Center de Pompidou in Paris in individual or group exhibitions as well as in the collection of the Tate Modern London, Metropolitan Museum of Art, MOMA and Guggenheim Museum in New York. With its diversified activities, the gallery organizes monthly exhibitions in its exhibition space based in Budapest. A long-term relationship of trust with museums and private collectors has resulted in exhibitions at the Ludwig Museum in Budapest, the Műcsarnok, the Modem in Debrecen and the Ferenczy Museum in Szentendre. It publishes richly illustrated art albums, monographs and catalogs in three languages for their artists. Since 2018, a series of conversation books has been published at the end of each year, mostly for current and future gallerists, art historians and researchers who are looking for information about the development of the art trade before and immediately after the change of regime in Hungary and for its participants as collectors, art dealers and museum professionals. In 10-20-30 years, many will no longer be able to share the stories that the gallery wants to document and preserve for posterity through these publications. It is recommended even for people who are not so close to the fine arts, but still want to get a glimpse into this closed world.

The gallery is a member of prestigious international art organizations:
- S.N.A. (Syndicat National des Antiquaires Négociants en Object d’Art Tableaux
anciens et modernes de France)
- The Belgian Royal Chamber of Antiques andArt Dealers
- CINOA The International Federation of Dealer Associations
