What is Anthropic? The company behind Claude
A plain-English background on Anthropic: who founded it, what it builds, how it makes money, and why investors are paying attention ahead of a possible IPO.
Anthropic is an AI safety and research company, best known as the maker of Claude, a family of frontier large language models. This is the background an investor needs before digging into the numbers.
The basics
- Founded: 2021, by siblings Dario and Daniela Amodei and a group of former OpenAI researchers.
- Headquarters: San Francisco, California.
- Flagship product: Claude, used via chat, an API, and the Claude Code agent.
- Mission framing: building reliable, interpretable, and steerable AI systems.
How Anthropic makes money
Revenue comes primarily from selling access to Claude: API usage by developers and businesses, enterprise contracts, and subscription tiers (Claude Pro and Max). Claude Code, an AI coding agent, has become a major growth driver in its own right.
Why investors care
Two reasons. First, growth: run-rate revenue scaled roughly 5x in under a year. Second, strategic backing: Amazon and Google are both major investors and infrastructure partners, which de-risks compute and distribution.
Where it sits in the market
Anthropic is the primary rival to OpenAI at the frontier of AI capability. As of mid-2026 it is the most valuable private AI company in the world by valuation.
