The dealer as consultant: selling expertise beyond the exhibition space

01The dealer's legitimacy as adviser

The question of legitimacy arises immediately. A dealer who advises a collector while representing artists whose works they sell finds themselves in a potential conflict-of-interest situation that their interlocutors will not fail to raise. Yet this objection, though legitimate, does not withstand a thorough examination of market reality. The most respected independent art advisors — Thea Westreich Wagner and Ethan Wagner in New York, Wentrup Advisory in Berlin, Sandy Heller in the United States — themselves acknowledge that their market knowledge rests largely on their relationships with galleries and artists. The dealer who agrees to play an advisory role is merely formalising a practice that has existed informally since the profession began.

Galerie Kamel Mennour in Paris illustrates this porosity. When a loyal collector asks for advice on acquiring a work not in the gallery's programme, the dealer guides, recommends and makes introductions. This advisory activity is not invoiced as such, but it cements a relationship of trust that generates direct sales over the long term. Other dealers have chosen to formalise this dimension by creating a distinct advisory structure, with transparent fees and a clearly defined scope of intervention. Transparency about this dual role is the sine qua non of credibility: a dealer who conceals their commercial interests behind the guise of a neutral adviser will quickly lose credibility in a milieu where information travels fast.

02Marketable areas of expertise

The dealer possesses several competencies whose commercial value is underestimated. The first is valuation. Estimating the value of a work of art requires knowledge of market prices, career trajectories, pricing dynamics and institutional trends that few professionals master as well as an active dealer. Private banks, family offices, specialist insurers and law firms involved in estates or divorces regularly need this expertise. A dealer with twenty or thirty years of experience in a precise market segment — contemporary photography, post-war abstract art, emerging French creation — possesses knowledge that no academic training can replace.

The second competency is collection building. Guiding a collector through the construction of a coherent ensemble, articulated around a vision and guiding principle, constitutes a high-value-added service. Galerie Lelong in Paris has historically played this role for several major collectors, steering them towards artists and works that fitted the logic of their collection. Thomas Dane Gallery in London accompanies its collectors in a reflection that extends beyond the simple one-off purchase and embraces a long-term wealth-building approach.

The third competency is exhibition curating. Companies, hotels, public spaces and private residences wishing to integrate contemporary art into their environments seek professionals capable of designing a coherent artistic project, selecting works, supervising installation and providing mediation. The dealer is naturally positioned for this type of mission. Galleria Continua, based in Italy, France, Cuba and Brazil, has developed this off-site curating activity significantly, intervening in architectural and landscape contexts that extend beyond the traditional gallery framework.

03Structuring an advisory offering without compromising the gallery

The transition to advisory work requires reflection on legal and commercial structure. Some dealers choose to create a separate entity, with a distinct name and visual identity, to avoid any confusion between their dealing activity and their advisory activity. Others integrate advisory as an additional gallery service, presenting it as a natural extension of their expertise. Both models work, provided that the rules of engagement are clear from the outset.

In both cases, transparency on fees is essential. Advisory can be billed as a flat fee, hourly fees or a commission on acquisitions made, generally between five and fifteen per cent of the purchase price. The chosen formula depends on context and client, but it must be explained and agreed upon before any collaboration begins. The dealer-consultant must also define the limits of their intervention. Advising a client on acquisitions of works they do not sell themselves is an exercise requiring rigorous intellectual discipline. Recommendations must be founded on the quality of the work and its relevance to the client's collection, not on the dealer's personal relationships with other galleries. The adviser's reputation rests entirely on their ability to put the client's interests first.

04The corporate collections market

Companies represent a particularly buoyant advisory market. Corporate collections have expanded considerably over the past two decades, driven by growing awareness of the role of art in workplace attractiveness, corporate culture and brand image. Deutsche Bank owns a collection of more than fifty thousand works. The Societe Generale collection in France, the UBS collection in Switzerland and the Lhoist collection in Belgium illustrate the scale of the phenomenon.

A dealer wishing to enter this market must understand the specific constraints of companies. Budgets are subject to validation processes involving finance departments, works councils and sometimes boards of directors. Artistic choices must be defended before interlocutors who are not specialists and who reason in terms of return on investment, brand consistency and employee acceptability. Works must be suited to work environments where security and maintenance pose particular problems. Galerie RX in Paris has developed recognised expertise in supporting companies, offering a comprehensive service from artistic project design to logistics management. The gallery has built a portfolio of institutional clients that represents a significant complement to its gallery activity.

05Advising on art wealth management

A rapidly growing segment is art wealth management advisory. Collectors who have built significant holdings over the years face questions of conservation, insurance, taxation, transmission and potential monetisation whose complexity exceeds their own competencies. The dealer who knows the collection's history, the artists represented and market dynamics is a natural interlocutor for these decisions.

The question of succession is particularly sensitive. When a collector dies, their heirs face a body of work whose value, historical importance and optimal conditions of sale they may not fully understand. The dealer who accompanied the collector for years is often the first contact for the heirs. This position confers an advisory role that can become a sales mandate, mediation commission or guidance towards an institutional donation. Galerie Applicat-Prazan in Paris, specialising in post-war and modern art, has developed a wealth advisory activity that constitutes an important part of its overall business. Tornabuoni Art, between Florence and Paris, accompanies collectors in managing collections that include works by twentieth-century Italian masters, a segment where the dealer's expertise is irreplaceable.

06Training as a legitimacy vector

The dealer who gives lectures, participates in training programmes, publishes articles or leads guided tours builds an expert visibility that naturally feeds their advisory activity. Leading business schools, continuing education programmes in wealth management and collector circles regularly organise interventions by art market professionals. These opportunities are time investments that generate indirect returns in the form of contacts, mandates and referrals. Thaddaeus Ropac regularly participates in conferences and academic programmes, strengthening his expert position beyond his dealing activity. The Kadist Foundation in Paris organises training programmes for collectors in which dealers and curators participate, in a spirit of knowledge sharing that benefits the entire ecosystem.

Publishing is another credibility vector. The dealer who writes catalogue essays, contributes to collective publications or maintains a specialised newsletter produces content that tangibly demonstrates their expertise. These publications become intellectual calling cards that the dealer can use when prospecting potential clients.

07Digital tools as a lever for remote advisory

The 2020-2021 pandemic accelerated the digitalisation of art advisory. Virtual studio visits, video consultations and digital presentations of work selections have become standard practices that allow the dealer-consultant to extend their reach well beyond their geographic location. A Parisian dealer can now advise a collector in Hong Kong, Sao Paulo or Lagos without leaving their office. This geographic extension is particularly relevant for dealers specialising in niche segments — contemporary African art, Japanese photography, Latin American kinetic art — whose clientele is by nature dispersed worldwide.

For Artedusa partner galleries, the platform offers a natural framework for extending this advisory activity online. Presenting curated selections, contextualising works and creating collection pathways on the platform constitute services that position the dealer as an expert whose knowledge extends beyond the physical limits of their exhibition space.
