JMC Family Office
Jean-Marie Painvin spent decades building Deutsch Group into a global high-performance connector manufacturer with over 3,500 employees across 25 countries before orchestrating its $2.1 billion sale to TE Connectivity in April 2012. That liquidity event seeded JMC Family Office, which he founded later that year as a single-family vehicle headquartered in New York. Painvin remains CEO and is supported by his sons — Gregoire, who rejoined in 2025 to oversee liquid portfolios and alternatives, and Morgan, who advises the JMC Family Foundation. The firm deploys capital through three operating entities. JMC Investment makes direct control and minority investments in operating companies, with a portfolio spanning engineered industrial products (Amerequip), composite manufacturing for aerospace and defense (Hawthorn Composites), medical devices (Leuko), and premium floristry (Ode à la Rose). JMC Asset Management oversees liquid portfolios and alternative investments, while JMC Sport targets the sports and wellness vertical. The office has also invested in electrical engineering services (JTI) and medical imaging (Keosys). It invests across North America and Europe, with a stage appetite that includes buyout and growth. Ten professionals are listed on the firm's website, with Jean-Marie Painvin leading alongside CFO Tom Sadusky and deal leads Emily Kochanowicz and John Bagge. In September 2025, JMC hired Jackie Sauer from Boston Consulting Group's private equity practice to join the direct investment team. The firm maintains its headquarters at 55 Fifth Avenue in New York and lists no additional offices, though family members operate from Boulder, Colorado, and Paris. Painvin is a member of Piping Rock Golf and Country Club in New York, Morfontaine in Paris, and Manville in Maussane-les-Alpilles. The firm's structure integrates both operating company control and minority direct investing with a separate philanthropic foundation. The JMC Family Foundation, led by Director Erika Marte, focuses on sustainable charitable partnerships with under-resourced communities, while Painvin personally serves on the board of grantee Summer Search. Painvin's own board seats — including Parrot SA and Amerequip — create a governance layer that connects the family's oversight to portfolio operations more tightly than a traditional fund structure would.

Frequently asked questions
Who runs investment decisions at JMC Family Office?
Jean-Marie Painvin, as Founder and CEO, sets the overall investment strategy. Deal sourcing and execution for direct investments are led by Emily Kochanowicz, a Principal who has been with the firm since 2012, and John Bagge, Director of Direct Investments since February 2022. Gregoire Painvin rejoined in 2025 to oversee liquid portfolios and alternative investments.
How is JMC Family Office structured across its entities?
JMC operates through three entities. JMC Investment handles direct control and minority investments in operating companies. JMC Asset Management oversees liquid portfolios and alternative investments. JMC Sport focuses on the sports and wellness vertical. A separate JMC Family Foundation manages the family's philanthropic grantmaking.
Does JMC Family Office participate in fund commitments or only direct deals?
The office conducts both direct investments and alternative fund commitments. JMC Investment targets direct operating company deals, while the 2025 hiring of Gregoire Painvin to oversee alternative investments confirms dedicated fund and liquid portfolio activity alongside the direct investment arm.
Which sectors does JMC Family Office explicitly avoid?
JMC does not publish a formal exclusions list. Its disclosed portfolio and sector focuses — industrial technology, aerospace composites, medical devices, and premium services — suggest the firm avoids consumer internet, enterprise SaaS, and financial services, but this absence is observed rather than stated policy.
How is JMC Family Office's philanthropy separated from its investment activities?
The JMC Family Foundation is a distinct entity under the family office umbrella, led by Director Erika Marte and advised by Morgan Painvin. It operates with its own strategic direction focused on long-term charitable partnerships, while Jean-Marie Painvin's personal board service at grantee Summer Search creates a governance link between the two arms.
What is JMC's known posture on co-investments alongside external GPs?
The firm actively builds co-investment relationships. John Bagge was hired in February 2022 with an explicit mandate to expand JMC's co-investor network. Winklevoss Capital appears as a related entity in investor networks, suggesting established co-investment activity, though no specific co-investment deals are publicly disclosed.
Where does JMC Family Office source its deal flow from?
The office appears to source deals through the founder's industrial operating network and the investment team's professional relationships. Jean-Marie Painvin's board seats — on Parrot SA, Amerequip, and Ode à la Rose — and the team's prior tenures at Hilco Global, BCG, and Houlihan Lokey provide specialized origination channels rather than the auction processes typical of institutional managers.
