Anthropic

Founded in 2021 by ex-OpenAI researchers Dario and Daniela Amodei, Anthropic has raised $7.3 billion including a $4B Amazon investment to build Claude AI, making it better funded than average AI startups by 15x. Its Constitutional AI framework sets the gold standard for AI alignment, reducing harmful outputs by 80% compared to OpenAI's GPT-4o in safety benchmarks, making it the safety-first counterweight to OpenAI.
