Billionaire Founders Still Running Their Companies: A March 2026 Snapshot

Twenty-five exceptionally wealthy founders who held an operating leadership role at the March 2026 snapshot, selected across technology, finance, industry, retail and healthcare. Entries run from highest to lowest estimated personal net worth in Forbes’s 2026 annual list, valued on 1 March in US dollars; bn means billion. This is a selected comparison, not an exhaustive ranking of every eligible founder. Co-founders, co-CEOs and equivalent chief executive titles qualify; a board seat or ownership alone does not. Each entry identifies the actual company and role, including founder-led subsidiaries. Figures are historical estimates of total personal wealth, not salaries, cash balances or the value of just one holding.
