Peel started her career in the equities division of Goldman Sachs in 1997 in London, and became an executive director before leaving in 2003.
Outset Contemporary Art Fund
Peel co-founded the charity Outset Contemporary Art Fund in 2003 with Candida Gertler. Peel and Gertler generated a model whereby artists could be presented to potential donors in order to raise funds to purchase their work, or to fund new commissions with a view to donating them to public institutions. The Fund purchased over 100 pieces for the Tate Modern, and commissioned work by artists including Francis Alys, Yael Bartana, Candice Breitz and Steve McQueen.
Intelligence Squared
In 2009, Peel co-founded Intelligence Squared Asia with Amelie Von Wedel, a not-for-profit platform for hosting live debates in Hong Kong. In 2012 Peel became CEO of Intelligence Squared Group, bringing the live events business out of its financial difficulties. Peel has hosted interviews including: Olafur Eliasson and Shirin Neshat at Davos, Ai Wei Wei at the Cambridge Union.
Serpentine Galleries
In April 2016, Peel was appointed to the role of CEO of the Serpentine Galleries. Peel said it was her "mission to create a safe space for unsafe ideas", and to promote a "socially conscious Serpentine". She indicated that she wanted to give artists a greater say in the development of the Serpentine Galleries, in order to give "artists a voice in the biggest global conversations". Peel worked in tandem with the artistic director, Hans Ulrich Obrist. Peel furthered the Serpentine Galleries' technological ambitions, introducing digital engagement initiatives including Serpentine Mobile Tours and the translation of the exhibition Zaha Hadid: Early Paintings and Drawings into Virtual Reality. Peel stated that she was "committed to maintaining and open-source spirit" at the Serpentine Galleries, and that it was her ambition "to inspire the widest audiences with the urgency of art and architecture". The Financial Times noted that Peel "has been able to lure companies such as Google and Bloomberg as partners to help meet the Serpentine's annual £9.5m target". Peel and Obrist selected both the first African architect to work on a pavilion, and the youngest architect to do so. In 2018, she broadened the global reach of the Serpentine Pavilion programme by announcing the launch of a pavilion in Beijing designed by Sichuan practice, Jiakun Architects. Together with Lord Richard Rogers and Sir David Adjaye, Peel and Obrist selected Burkina Faso architect Diébédo Francis Kéré to design the 2017 pavilion. The pavilion was awarded the Civic Trust Award in 2018. The Serpentine selected Mexican architect Frida Escobedo to design the 2018 pavilion. She will be the youngest architect to have participated in the Pavilion programme since it began in 2000. She stepped down as CEO in June 2019 as a consequence of the attention paid to her co-ownership of NSO Group, an Israeli cyberweapons company whose software has allegedly been used by authoritarian regimes to spy on dissidents.
Philanthropy
Peel co-chaired Para Site, a not-for-profit contemporary art space in Hong Kong, from 2010 to 2015. She has been involved with the project since 2009. Peel founded the Victoria and Albert Museum's design fund in 2011. The fund supported the acquisition of contemporary design objects. Peel is a member of NSPCC's therapeutic board. Inspired by her children, in 2008 Peel produced a series of toddler-friendly art books published by Templar, including: Art For Baby, Color For Baby and Faces For Baby. These books feature works by artists ranging from Damien Hirst to Keith Haring. Proceeds from the sales of the books go towards the NSPCC.
