Anthropic is an American artificial intelligence (AI) startup founded in 2021 by former OpenAI executives Dario Amodei, Daniela Amodei, Jack Clark, Sam McCandlish, and Tom Brown. The founders left OpenAI over concerns about AI safety and alignment, particularly disagreeing on OpenAI’s partnerships and strategic direction. Anthropic was established as a public-benefit corporation, emphasizing the development of AI systems that are **safe, reliable, interpretable, and aligned with human values**—balancing shareholder interests with broader societal good[2][4][5]. Since its inception, Anthropic has rapidly grown both in workforce and market presence. From only 192 employees in 2022, it expanded to 1,097 employees globally by 2025, marking a nearly sixfold increase in three years, reflecting aggressive scaling especially in 2023-2024[1][3]. This workforce supports Anthropic’s mission to build large language models (LLMs) that are *helpful, honest, and harmless* while advancing techniques to make AI behavior more predictable and controllable[4]. Anthropic’s funding success is remarkable, having raised approximately $7.3 billion in multiple rounds within just a few years, including a $4 billion commitment from Amazon in 2024 and a record $13 billion financing round in September 2025. These investments have propelled the company's valuation to around $61.5 billion[2][3]. This financial backing underscores substantial investor confidence in Anthropic's vision and technology. The company is known for its flagship AI models like the “Claude” series, with recent releases such as Claude 3.5 and Claude Sonnet 4.5, which are competitive with industry leaders like GPT-4 in natural language understanding and coding tasks[2][6]. Anthropic also actively collaborates with academic institutions and regulators to formalize AI safety standards, reinforcing its leadership in ethical AI development[3].
