The Genesis of Anthropic: A Mission-Driven Beginning
The story of Anthropic begins with a fundamental disagreement about the direction of AI development. In 2021, seven former employees of OpenAI, led by siblings Dario and Daniela Amodei, made the bold decision to leave their prestigious positions to start something entirely new. This wasn’t just another Silicon Valley startup story driven by entrepreneurial ambition; it was a mission-driven exodus fueled by concerns about AI safety and the responsible development of increasingly powerful AI systems.
Dario Amodei, who had served as OpenAI’s Vice President of Research, brought with him a deep understanding of both the tremendous potential and inherent risks of advanced AI systems. His sister Daniela, formerly OpenAI’s VP of Safety and Policy, complemented this technical expertise with a keen focus on governance and ethical considerations. Together with their team of renowned researchers including Jack Clark and Chris Olah, they established Anthropic with a clear mission: to build AI systems that are reliable, interpretable, and steerable.
The timing of Anthropic’s founding was particularly significant. In 2021, the AI landscape was characterized by a race to develop increasingly powerful models, often with safety considerations taking a backseat to capability advancement. The founders recognized that this approach could lead to unintended consequences as AI systems became more sophisticated and widely deployed. Their vision was to demonstrate that it was possible to develop cutting-edge AI while maintaining rigorous safety standards throughout the development process.
From its inception, Anthropic structured itself differently from typical tech startups. The company incorporated as a Delaware public-benefit corporation (PBC), a legal structure that enables directors to balance financial interests with public benefit purposes. This governance model reflects the company’s commitment to prioritizing societal impact alongside commercial success, ensuring that profit motives don’t override safety considerations.
Revolutionary Funding: Building the Financial Foundation
Anthropic’s approach to funding has been as innovative as its approach to AI development. The company has raised an unprecedented $14.3 billion in total funding, making it one of the most well-capitalized startups in history. This massive influx of capital reflects both the enormous potential of AI technology and the significant computational resources required to compete at the frontier of AI development.
The funding journey began with an unconventional start.
