A New Type Of
Art Buying Experience.

Publicly launching in 2021, 5oz. was conceived by Stephan Weishaupt, taking a collaborative approach to partnerships with artists by offering a gallery environment that guides both a presentation and buying experience in a way that is highly individualised. Stemming from a life-long immersion in the art world and as an extension of his successful, multi-national design businesses, 5oz.’s approach is reflective of Weishaupt’s personal vision.

Showing art and interacting with clients in unconventionally personalised ways differentiates the brand from a typical gallery. Displayed in a network of settings in and around Toronto, Vancouver, New York, and Miami, including within private residences, accessible by appointment, and at AVENUE ROAD showrooms, roving exhibitions include a mix of represented artists’ works.

A consultative approach is taken to the service offering, which includes advising, sourcing, procurement, and logistics for bespoke commissions, in addition to selling pieces from artists included in the 5oz. roster.


For curator Stephan Weishaupt, it all comes down to relationships. Weishaupt’s intuition, world view, and above all, affinity for connecting people is what has enabled him to engineer truly original experiences.

Born and raised in Munich, Weishaupt’s relationship with his family — a long line of entrepreneurs, architects, and art patrons — imparted his insatiable curiosity and appreciation of art and design.

True to form, Weishaupt’s focus, and measure of success is the quality of the relationships he has built with both his clients and artists who have come to trust him as a true collaborator.
