At Anthropic, co-founder and CEO Dario Amodei has a singular direct report: Avital Balwit, the Chief of Staff. Dario dedicates the majority of his time to high-level dialogues, cultivating organizational culture, and engaging in discussions about research trajectories and strategic perspectives, rather than directly supervising senior executives. The day-to-day operations of the company are largely steered by Dario's sister and President, Daniela Amodei. Daniela is accountable to the board of directors, with the executive team also reporting to her. Dario asserts that this leadership model streamlines his ability to fulfill his responsibilities. As a first-time entrepreneur holding a PhD in biophysics, Dario initially embarked on his career as a researcher, frequently immersing himself in profound discussions about artificial intelligence and its implications for humanity. He estimates that he devotes half of his time to conversing with employees about company culture and operations, believing that nurturing the company culture stands as the paramount duty for both him and Daniela. Following its most recent funding round, Anthropic has achieved a valuation of nearly $1 trillion and is aiming to go public before OpenAI. Dario, who previously served as OpenAI's Vice President of Research, departed due to disagreements with the leadership and subsequently established Anthropic in 2021. Daniela, on the other hand, boasts a wealth of experience in personnel management within tech startups. She began her career at Stripe and later headed the safety and policy team at OpenAI.
