Sam Altman

Sam Altman is the CEO of OpenAI, the company behind ChatGPT and GPT-4, technologies that are rapidly transforming how advertisers create content, target audiences, and automate campaign workflows. While not a traditional AdTech operator, Altman's influence on the industry is profound — OpenAI's large language models and generative AI tools have been integrated into major advertising platforms including Google, Meta, and Microsoft, enabling AI-driven ad copy generation, creative optimization, and conversational commerce at scale. His work is accelerating the shift toward AI-native advertising infrastructure. Altman began his career as co-founder and CEO of Loopt, a location-based social networking startup backed by Y Combinator, before becoming President of Y Combinator in 2014 — one of the world's most influential startup accelerators. During his tenure at YC, he oversaw investments in hundreds of companies, many of which became foundational to the modern AdTech and MarTech stack. He co-founded OpenAI in 2015 alongside Elon Musk and others, and became CEO in 2019, steering the organization through its transition to a capped-profit model and its landmark partnership with Microsoft. In November 2023, Altman was briefly ousted by OpenAI's board before being reinstated within days following overwhelming support from employees and investors — an episode that underscored his centrality to the AI industry. Under his leadership, OpenAI has become the most prominent AI company in the world, with its models embedded in advertising workflows, search monetization strategies, and creative production pipelines across the global marketing industry.
