Frequently asked questions

Who runs investment decisions at JMC Investment?

Jean-Marie Painvin, Founder and CEO, has final authority on direct investments, supported by Managing Director Emily Kochanowicz and Director of Direct Investments John Bagge. Gregoire Painvin rejoined in 2025 to oversee liquid portfolios and alternatives. The investment committee is effectively the family — there is no outside capital and no external limited partners.

How does JMC source its direct deals?

The firm relies primarily on its network of industrial and financial relationships built during Jean-Marie Painvin's tenure at Deutsch Group. The team also cultivates co-investment partnerships and reviews opportunities through operating-company board seats. The website invites entrepreneurs to connect directly, suggesting a willingness to engage with founder-led deal flow.

Where does the underlying wealth come from?

The capital originated from the April 2012 sale of Deutsch Group, a high-performance connector manufacturer, to TE Connectivity for $2.1 billion. Jean-Marie Painvin was Chairman and CEO of Deutsch before the transaction and founded JMC Investment the same year.

Is JMC Investment structured as a family office or a venture firm?

It operates exclusively as a single-family office. The firm only manages Painvin family capital, does not market to outside investors, and structures its activities under a generalist mandate that spans buyouts of established industrial manufacturers and seed-stage venture checks.

What investment stages does JMC typically target?

JMC deploys across the full lifecycle: buyouts of middle-market operating companies, early-stage venture rounds, and seed investments. Manufacturing positions like Amerequip and Hawthorn Composites reflect control-oriented buyouts, while Leuko and Keosys represent venture bets.

Does JMC maintain philanthropic structures, and how are they separated?

Yes, the JMC Family Foundation operates as a distinct entity with its own Director, Erika Marte, and Foundation Advisor, Morgan Painvin. It funds organizations such as Summer Search and the ARAOK Foundation without commingling assets with the investment entity.

What is JMC's posture on co-investments alongside external GPs?

JMC actively seeks co-investment relationships. John Bagge, who joined in February 2022, leads efforts to expand these partnerships. The firm does not disclose a formal club or recurring co-investor pool, but its site emphasizes a distinctive partnership approach.
