William C. Durant

General Motors

General Motors was founded in 1908 as a holding company, not a manufacturer. It made money by acquiring brands and suppliers, issuing stock to secure alignment, and franchising dealerships — all before building a single integrated factory. Its early success came from financial engineering, not product innovation. Durant was removed twice — in 1910 and 1920 — exposing the fragility of growth without operational discipline. Sloan’s later reforms codified what Durant had improvised: a scalable, tiered brand architecture. The real innovation was not the car, but the corporation.
