Who are General Motors's decision-makers?

Mary Barra is GM's Chair and CEO and remains the central executive voice for product strategy, safety, capital allocation, and culture. Mark Reuss is a crucial operating leader for vehicle execution, while Paul Jacobson controls finance and capital discipline. Software, services, regional markets, manufacturing, procurement, and GM Financial leaders shape the practical roadmap underneath the CEO agenda.

GM buying committees depend on the category. Manufacturing and supply-chain vendors usually pass through procurement, plant operations, engineering, quality, and finance; software vendors pass through IT, cybersecurity, enterprise architecture, privacy, legal, and business owners; connected-vehicle vendors need product, software, data, and safety stakeholders. GM Financial has its own credit, risk, technology, and compliance buying path.

GM is a matrixed industrial enterprise with brands, regions, vehicle programs, manufacturing plants, engineering centers, software teams, and a captive finance subsidiary. That structure means large deals require stakeholder mapping by program and budget owner, not only an executive sponsor. Procurement maturity is high, and sellers should expect safety, quality, cybersecurity, data, supplier-risk, and financial reviews.
