Sam McCandlish, Anthropic cofounder and former chief technology officer, helped build one of the defining companies of the generative AI era while shaping the technical foundations behind Claude and Anthropic’s broader safety-driven approach to frontier models. A theoretical physicist by training and former OpenAI researcher, he became known for influential work on AI scaling and compute, then played a central role in Anthropic’s rise from high-conviction startup to one of the world’s most valuable AI companies. He later moved into the role of chief architect, underscoring his importance as one of the key technical minds behind Anthropic’s long-term direction.

Jared Kaplan, cofounder and chief science officer of Anthropic, has become one of the central technical figures in the generative AI boom, helping build the company behind Claude into a major force in large language models. A theoretical physicist by training and former OpenAI researcher, he is known for influential work on the scaling behavior of AI systems and for pairing frontier model development with a strong emphasis on safety and governance. As Anthropic’s influence has expanded, Kaplan has emerged as one of the key scientists shaping the next era of artificial intelligence.
