Mar 03, 2025 - techcrunch.com
AI startup Anthropic has raised $3.5 billion in a Series E funding round led by Lightspeed Venture Partners, reaching a post-money valuation of $61.5 billion. This round also saw participation from several other investors, bringing Anthropic's total funding to $18.2 billion. The company plans to use the funds to advance its AI systems, expand compute capacity, and accelerate international growth. Anthropic recently launched its latest AI model, Claude 3.7 Sonnet, which aims to simplify user experience by eliminating the need for multiple model choices. The company's revenue has grown by 30% in 2025, though it expects to burn $3 billion this year.

Anthropic is focusing on profitability by introducing new tools and subscription tiers, and has expanded its presence in Europe with new offices and high-profile hires. The company has strengthened its partnership with Amazon, which invested an additional $4 billion and is collaborating on AI chip optimization and the Alexa+ virtual assistant. Anthropic, co-founded in 2021 by former OpenAI VP of research Amodei, positions itself as more safety-focused than OpenAI, with several ex-OpenAI employees among its ranks.
