Sender's art collection includes core works from
Urs Fischer,
Keith Haring, and
Cindy Sherman. He began collecting in 1998 with Todd Levin as curator. Portions of the collection were sold in auctions in 2006 and 2014. He is a founding partner of the Parrish Trustees for the
Parrish Art Museum. Sender has served on the Business Committee of the
Metropolitan Museum of Art. Sender's home and office served as displays for Sender's collection. Den (Villa D'Este) by
Elizabeth Peyton was featured in the entrance of the Exis office, and
Edward Ruscha's black and white painting "Let's Be Realistic" hung outside the trading room. Other pieces in the office included a
Kara Walker mural, a pink and green neon sculpture by
Dan Flavin, and "The Activists" by
John Currin.
"Home Alone" Part of the collection went on display at the
Art Basel Miami Beach event in 2011. The showing, "Home Alone," was in a home Sender owned in Miami. The art was presented in such a way as to suggest that a family's art collection took over their home. Eighty-five pieces were featured in the display including
Richard Prince's "Spiritual America" and "Bumped," a photo by
Gilbert & George. Twenty-five
Raymond Pettibon prints overflowed from a bathroom. Eight
Sarah Lucas works took over the master bedroom. Other selections included new works by
Rashid Johnson, a floor installation by Jim Lambrie, and vinyl wall text in the kitchen by
Lawrence Weiner. ==Philanthropy and political activity==
