Anthropic
Founded 2021 · San Francisco, United StatesAnthropic PBC is an American artificial intelligence research and commercial company incorporated as a public benefit corporation. It was founded in 2021 by seven former OpenAI employees, including siblings Dario Amodei (CEO) and Daniela Amodei (President). The company is headquartered in San Francisco. Anthropic's primary product is the Claude family of large language models, available through a web and mobile interface (claude.ai), an API, Amazon Bedrock, Google Vertex AI, and desktop applications. The company conducts research into AI safety, model interpretability, and alignment with human values. Its methodology features the Constitutional AI (CAI) technique, in which a model is trained against a defined set of principles. Key products also include Claude Code (an agentic coding tool) and Claude Cowork (a desktop assistant for non-technical users). In February 2026, Anthropic closed a Series G funding round of $30 billion at a valuation of $380 billion. The company serves more than 300,000 business customers and maintains offices in 12 cities worldwide.
