Our online artist community is made up of individual artists, which requires each artist to have their own profile. Therefore, at this point in time we do not accept galleries or groups of artists to be part of an umbrella agent profile.
However, if you want to sign an artist up directly and manage their profile on their behalf, you must be authorized to do so.
Please also note that we work with artists directly, not gallerists or agents. If artists have gallery/agent deals that influence the artists net (i.e. paying a gallery or representative a proportion of the artist fee), it's the artist responsibility to coordinate this outside of any Indiewalls transactions.
