Anthropic

Anthropic is the AI safety company co-founded by Dario Amodei and his sister Daniela Amodei in 2021, along with a cohort of senior researchers who had departed OpenAI. The founding thesis was that the development of increasingly powerful AI systems required an institution whose primary commitment was safety — not as a marketing posture or regulatory concession but as a research program, an organizational culture, and a design philosophy embedded in every decision from architecture to deployment. The company pursues capability because capability is the condition under which safety research becomes meaningful, but with the institutional commitment that safety research advances at the same pace as capability research. By 2025, the company had received over $7 billion in funding from Amazon, Google, and other investors, developed the Claude family of models, and published foundational work on Constitutional AI, interpretability, and responsible scaling.
