    Our edge

    Operator DNA

    We’ve shipped production systems across storage, security, and media. We underwrite with lived context.

    Compounders Only

    Preference for durable cash flows, clear unit economics, and reinvestment runways.

    Aligned Governance

    Board discipline, clean cap tables, and transparent reporting. No drama, just performance.

    Playbook

    From deal sourcing to liquidity, we institutionalize cadence: scorecards, SLOs, and succession.

    Letter from the manager

    The McMahon Fund exists to back practical builders and create durable value. We prefer steady compounding to flashy headlines, and we publish transparent reporting to keep ourselves honest. If that resonates, we’d love to talk.
