Sasha de Marigny is the Chief Communications Officer at 📝Anthropic, the first person to hold the title at the company. She oversees communications, editorial, and brand.
De Marigny was promoted to CCO in November 2025, having previously served as Head of Communications. Under her leadership, the comms and brand team has tripled in size to approximately 80 people, with continued expansion planned for international markets. She works alongside Andrew Stirk, Anthropic's Head of Brand, to shape the company's public identity and narrative.
Her strategic focus centers on grounding Anthropic's brand story in the company's structure and founding philosophy — positioning Claude as an ethical, safety-first AI. She has described her team's work as listening to diverse communities — business leaders, developers, artists, and educators — to understand concerns and shape public perception around AI technology. The team's rapid growth reflects Anthropic's transition from research lab to consumer-facing brand during a period of intense public scrutiny of AI companies.
