Who are OpenAI's decision-makers?

Sam Altman, co-founder and CEO since 2019, sets strategy and is OpenAI's public face; he was previously president of Y Combinator. Co-founder and President Greg Brockman, formerly CTO of Stripe, runs technical strategy and the Stargate infrastructure/compute build-out, while COO Brad Lightcap owns global operations, go-to-market, and partnerships.

The research org is led by Chief Scientist Jakub Pachocki, who succeeded Ilya Sutskever in 2024 and sets long-term research goals. Product sits with Chief Product Officer Kevin Weil (ex-Instagram, Twitter, Planet), and finance, capital markets, and IPO readiness sit with CFO Sarah Friar, who joined in 2024 after serving as CEO of Nextdoor and CFO of Square (now Block).

Strategy and the largest compute/infrastructure commitments run through Sam Altman, Greg Brockman, and Brad Lightcap, who own the relationships with cloud, chip, and data-center partners. Day-to-day budget authority for finance, procurement, and corporate vendors sits with CFO Sarah Friar's organization, which is professionalizing spend controls ahead of a public listing.

For most B2B software and services, the buying committee is the relevant functional VP or director (heads of infrastructure, security, data, IT, finance ops, or people/HR) who owns the budget, with finance and security/compliance as gatekeepers. Strategy is set at the top, but the economic buyer for a given tool is usually the function leader plus Friar's finance team — so map the specific function you serve rather than selling to 'OpenAI' in the abstract.

OpenAI has grown to roughly 4,500 employees and is structured around research, applied/product, infrastructure (compute and Stargate), go-to-market (consumer, enterprise, API), and corporate functions (finance, legal, security, people). The 2024-2026 raises funded a rapid build-out of enterprise sales, security, and finance to match the company's commercial scale.

A further wrinkle is governance: after the October 2025 restructuring, the for-profit operates as OpenAI Group PBC under the nonprofit OpenAI Foundation, which appoints the board. As it heads toward an IPO, OpenAI is layering in the controls and investor-relations machinery of a public company under Friar — which means more formal procurement, security review, and vendor management than a typical startup of similar age.
