JMC Family Office
Jean-Marie Painvin established the office after serving as Chairman and CEO of Deutsch Group, which he grew into a global connector manufacturer with operations in over 25 countries. The 2012 transaction that transferred Deutsch to TE Connectivity for $2.1 billion supplied the capital base. Painvin, a Rice University mechanical engineering graduate, continues to serve on boards including Parrot SA and Amerequip. The office executes through direct co-investments and SPVs alongside real estate holdings. It targets North American opportunities and maintains exposure to consumer technology via select operating-company partnerships. Deployment occurs without fund vehicles or third-party capital commitments. Geographic focus remains concentrated in the United States with limited international board representation. The team includes nine named professionals. Gregoire Painvin rejoined in 2025 to manage liquid portfolios and alternatives. Jackie Sauer joined the direct investment team in September 2025. The JMC Family Foundation operates as a separate grantmaking vehicle focused on education and community programs. No additional offices are disclosed. The structure keeps investment decisions inside the family with direct board participation by principals. This model limits external mandates and emphasizes long-term ownership over fund commitments or broad syndication.
