Mattern Capital Management

Mattern Capital Management

Richard Mattern launched Mattern Capital Management in 2020 after a career in financial services that generated the family's wealth. The firm operates as a single-family office managed by Richard and his son John Mattern. The firm deploys capital across private credit, real estate, and infrastructure, with a focus on direct investments and co-investments alongside institutional partners. It targets North American assets, with a preference for energy and renewable power projects that generate stable cash flows. Known co-investors include global infrastructure funds (per public record, 2023). Mattern Capital Management runs a lean operation with no disclosed team size or additional offices. The firm does not raise external capital and does not maintain a separate philanthropic entity in public records. A recent activity: January 2025 — Completed a direct co-investment in a Texas-based renewable energy portfolio alongside a large infrastructure manager (per public record, January 2025). The firm's structural differentiator is its complete avoidance of commingled funds — every deal is a direct or co-investment, giving full control over capital allocation and exit timing. The succession structure with Richard and John Mattern as co-principals provides continuity.
