Anthropic is an American @Artificial Intelligence (AI) safety company founded in 2021, headquartered in @San Francisco, CA. Co-founded by @Dario Amodei (CEO) and Daniela Amodei (President), alongside other ex-@OpenAI researchers who departed over AI ethics and safety concerns. Mission: "AI research and products that put safety at the frontier." Develops steerable, interpretable, and robust AI systems via Constitutional AI (CAI) — a methodology that embeds human-controllable values directly into large language models. Key Products: Claude — flagship family of @Large Language Models (LLMs) available via Claude.ai consumer app and @Anthropic API. @Claude Code (Anthropic) — an agentic coding @Command Line Interface (CLI) that enables Claude to write, edit, debug, and run code in developer environments. @Model Context Protocol (MCP) — an open protocol for AI tool use, donated to the Linux Foundation in December 2025. Business Model: API licensing, enterprise AI products, and consumer Claude subscriptions (Free, Pro, Team, Enterprise). Core focus on agentic coding workflows and enterprise-grade AI deployment.Funding & Scale: ~$33.7B+ raised as of early 2026. Most recent round: Series G — $30B at a $380B post-money valuation. Major investors include @Google, @Amazon (Claude available via AWS Bedrock), @Goldman Sachs, and ICONIQ. Approximately 4,155 employees. Private company. Anthropic is the maker of ClaudeCode, and ClaudeCode is what got me to finally start coding and pushing code to @GitHub. After 10 years of saying that I don't identify as an engineer, it is singularly the thing that made me identify differently. It is the engine behind @BrianBot (Local), and many of the projects that roll out of that.
