The boardroom finally
    has a scoreboard.

    The era of corporate transparency has transformed how we evaluate CEOs—but it largely stops at the boardroom door. Using public data—from SEC filings to governance disclosures and market signals—we quantify boardroom impact.

    If your impact can't be measured—or isn't visible—it's worth asking:
    Why are you on the board at all?

    The Dataset

    Boardminder currently tracks 4,655 board seats across 409 publicly traded companies in the 2026 Fortune 500. Companies are matched and verified using public company records and SEC filings. Coverage reflects companies for which Boardminder has established sufficiently reliable public board data and does not include private companies. It is not an official Fortune dataset.
