What Stretton Society does

Stretton Society e.V. is a Berlin-registered non-profit association (eingetragener Verein) founded in 2021 by Stephan Jansen, Maximilian von Schierstädt, and Johannes Freiherr von Salmuth, and co-initiated with Stretton Violins GmbH, which serves as a strategic operating parent. Its principal mandate is to grant selected world-class string musicians free access to rare historical instruments by Antonio Stradivari, Guarneri del Gesù, Guadagnini, Tecchler, and other master makers, with more than 30 artists placed on loaned instruments since inception, including Leonidas Kavakos, Vilde Frang, Pablo Ferrández, Sergey Khachatryan, and Amihai Grosz.

The organization operates four primary program lines: Stretton Seasons (festival series in St. Moritz, Bad Saarow, and Vienna), Stretton xMP (an Excellence Mentorship Program in Düsseldorf for musicians aged 12–27), Stretton Specials (invitation-only private chamber-music evenings at venues including Kensington Palace, Carnegie Hall, the Secession, and the Austrian National Library), and Stretton Stories (an editorial newsletter distributed via Brevo). Programmatic artistic direction is provided by Kian Soltani, Amihai Grosz, and Vienna Philharmonic concertmasters Rainer Honeck and Albena Danailova.

The Society is funded by an international network of philanthropists and patrons across Europe, the US, the Gulf, and Asia, supplemented by partner referral channels through LGT Private Banking and Platoon Aviation. Pricing and membership economics are not publicly disclosed. In 2024, the Society was awarded the European Cultural Award (Initiative Award category) and announced a strategic partnership with Opernhaus Zürich. H.S.H. Prince Max von und zu Liechtenstein serves as Honorary Board Member. The organization operates with a small staff of 1–10 employees and no public revenue disclosure.

Direct peers

• Nippon Music Foundation: Established Japanese foundation that owns and loans Stradivari, Guarneri del Gesù, and other rare stringed instruments to leading international soloists. Most directly comparable to Stretton Society's instrument-loan program in mission and operating model.
• Deutsche Stiftung Musikleben: German non-profit foundation that supports outstanding young string musicians through instrument loans, scholarships, and patronage networks. Closest German peer to Stretton, with overlapping artist pipeline and donor base.
• Stradivari Society of Chicago: U.S. non-profit that places rare historical stringed instruments with concert artists and supports classical music education. Direct competitor in the rare instrument loan market and a model for Stretton's planned North American expansion.
• Beare's International Violin Society: London-based dealer and society that brokers rare instrument loans across the international artist community. Compares on instrument placement infrastructure and artist relationships.
• Kronberg Academy Foundation: German foundation supporting exceptionally gifted young string soloists through mentorship, masterclasses, and career development. Directly overlaps with Stretton xMP in mission and target demographic.
• Anne-Sophie Mutter Foundation: Foundation of a globally leading violinist supporting young string players through instrument loans and scholarships. Closely comparable mentoring-plus-instrument stewardship model.
• Reuning & Company Violins: Boston-based violin dealer with a long-standing concert-artist instrument loan program and collector advisory practice. Comparable in artist placement and U.S. donor cultivation.

Broad incumbents

• Florian Leonhard Fine Violins: International violin dealer and brokerage that also advises collectors and places instruments with leading artists. Overlaps with Stretton in instrument stewardship and artist relationships, but operates as a commercial dealer rather than a non-profit.
• Colburn School: Los Angeles performing arts institution with a rare instrument collection supporting students and faculty. Wider in scope (full conservatory) but overlaps on instrument stewardship and young-artist development.

Others

• Tarisio: Leading international auction house for fine and rare stringed instruments and bows. Adjacent ecosystem participant that sources the secondary market from which Stretton patrons acquire instruments.
