Isabella Ritter was established in 2025, building on the ten-year legacy of LambdaLambdaLambda (2015–2025).

Based in Paris, the gallery emerges in response to the shifting dynamics of the contemporary art market. Its flexible structure allows for the development of projects, exhibitions, and collaborations that adapt to the evolving needs of artists and audiences. Isabella Ritter is conceived as a platform to rethink how artistic support structures can evolve–remaining closely involved at every stage of production while working in dialogue with its represented artists.

The gallery collaborates with kindred galleries, institutions, curators, advisers, and other partners to realize projects across diverse contexts and geographies.

Currently, Isabella Ritter operates from its Paris office, with viewings available by invitation and appointment only. Collaborative exhibitions take place internationally.
