Frieze Founders Step Back as Victoria Siddall Assumes Leadership of London and New York Fairs

institutional · 2026-04-20

Amanda Sharp and Matthew Slotover have reduced their operational roles at Frieze London and Frieze Masters, the fairs they established. Victoria Siddall, a long-serving Frieze employee, now manages daily operations with support from recently appointed deputies. Her responsibilities include gallery selection and oversight of nonprofit initiatives and public programs. While the founders' future plans remain undisclosed, Slotover traveled to Beijing last winter to introduce Frieze content on Chinese social media platforms, sparking speculation about potential Asian expansion. In London, Slotover chairs the board of South London Gallery and serves on the board of Create London, a nonprofit that commissions community-focused public art projects in the city's East End. Sharp and Slotover have not publicly detailed their activities since stepping back.
