Anthropic Company and Claude AI: Full History, Development, Advantages, and Financial Success
In the world of artificial intelligence, where competition grows every day, Anthropic stands out with its emphasis on safety and ethics. Founded in 2021, it quickly became one of the leaders in developing large language models (LLM). Its flagship product — Claude AI — has gained popularity due to its reliability, usefulness, and minimal risks. In this extensive article, we will thoroughly examine the history of Anthropic's founding, the process of creating Claude, the creators' motivations, the company's turnover at the end of 2025, as well as the key advantages of this AI. We rely on current data as of November 2025 to provide a complete picture. The article will be illustrated with relevant images for better understanding.
History of Anthropic's Founding: From Idea to Global Player
Anthropic was founded in 2021 by a group of former high-level OpenAI employees who decided to create a company focused on the safe development of AI. This happened amid growing concerns about the potential risks from superintelligent AI. The founders believed that existing approaches to AI development did not sufficiently account for ethical aspects and long-term consequences for humanity.
The company started as Anthropic PBC (Public Benefit Corporation), which underscores its mission: to create AI that benefits society while minimizing harm. The name "Anthropic" refers to the anthropic principle in cosmology, implying that AI should be oriented toward human values. From the beginning, Anthropic attracted investments from leading players such as Google and Amazon, allowing for rapid scaling.
Key development stages:
2021: Company founding. Initial focus on research in AI safety.
2022: Development of first Claude prototypes, raising $580 million in Series B.
2023: Launch of Claude 1.0, partnerships with Slack and Zoom for AI integration.
2024: Release of Claude 3 family (Haiku, Sonnet, Opus), $4 billion investment from Amazon.
2025: Release of Claude 4.5 and Haiku 4.5, significant revenue growth, recognition in TIME100 Most Influential Companies.
By 2025, Anthropic has grown to a team of hundreds of specialists, with offices in San Francisco and other cities. The company has evolved from an ethical startup to a global tech giant, competing with OpenAI and Google AI.
Who Created Anthropic and Why?
The founders of Anthropic are siblings Dario Amodei and Daniela Amodei. Dario, a physicist by education (PhD from Princeton), was previously Vice President of Research at OpenAI, where he worked on GPT-2 and GPT-3. Daniela handled operations and safety at the same company.
Other key co-founders:
Tom Brown — engineer who worked on model scaling.
Sam McCandlish — AI alignment specialist.
Jack Clark — policy director.
Why did they create Anthropic? In 2020-2021, disagreements arose at OpenAI regarding the pace of AI development and safety priorities. Amodei and the team believed that AI could become too powerful, potentially causing catastrophic risks if not ethically controlled. They left to found a company where safety is not a side effect but a core principle. Motivation: "Create AI that is helpful, honest, and harmless."
Dario Amodei often emphasizes in interviews: "We want AI to empower humanity, not threaten it." This is reflected in their Constitutional AI approach, where the model is "trained" to follow a constitution — a set of ethical rules.

How the Claude Tool Was Created: From Concept to Reality
Claude is a family of large language models developed by Anthropic. The creation process began in 2021 with research in AI alignment (aligning AI with human values). Unlike other models, Claude uses a unique training method: Constitutional AI. This means the model is not just trained on data but also "self-monitors" based on predefined principles to avoid harmful content.
Development stages:
Prototypes (2021-2022): The team experimented with transformer-based models similar to GPT. Focus on safety: models trained to refuse harmful requests.
Claude 1.0 (2023): First public release. Model with 100k token context, strong in text analysis and coding. Integration into Slack as a chatbot.
Claude 2 (2023): Improvements in speed, context up to 200k tokens. Added multimodality (image processing).
Claude 3 (2024): Model family — Haiku (fast, cheap), Sonnet (balanced), Opus (most powerful). Opus outperformed GPT-4 in intelligence tests.
Claude 3.5 (2024): Even smarter Sonnet version, with improvements in coding and visual analysis.
Claude 4.5 and Haiku 4.5 (2025): Major upgrades, focusing on complex tasks like scientific research and creativity, with enhanced introspection and tool use.
Claude was created using massive datasets but with thorough filtering for ethics. Anthropic invested in supercomputers from AWS and Google Cloud for training. The goal is not just power but reliability: Claude hallucinates less (invents facts) and always explains its reasoning.
Advantages of Claude: Why This AI Stands Out
Claude offers numerous advantages compared to competitors like ChatGPT or Gemini. Here are the key ones:
Safety and Ethics: Thanks to Constitutional AI, Claude refuses harmful requests (e.g., instructions for creating weapons). This makes it ideal for business and education.
Large Context: Up to 200k tokens (equivalent to 150k words), allowing analysis of entire books or codebases at once.
Multimodality: Starting from Claude 3, the model understands images, diagrams, and even generates code based on visuals.
High Accuracy: In benchmarks, Claude 4.5 outperforms competitors in math, coding, and reasoning. For example, in GPQA test (graduate-level questions) — 74% accuracy.
Integrations and API: Easily integrates into applications via API. Clients like Salesforce use it for analytics.
Speed and Cost: Haiku — fast and cheap for simple tasks, Opus — for complex ones. Prices: from $0.25/million tokens.
Transparency: Claude always explains thinking steps, useful for developers and analysts.
In 2025, Claude is used in healthcare (medical data analysis), finance (forecasts), and creativity (content generation). Advantage in B2B: 80% of revenue from enterprise clients.

Financial Indicators: Turnover at the End of 2025
Anthropic demonstrates explosive growth. By the end of 2024, annual recurring revenue (ARR) was $1 billion. In 2025, the company reached $5 billion ARR by August and projects $9 billion by year-end. This makes it one of the fastest-growing tech companies.
In 2025, Anthropic raised $13 billion in Series F, reaching a valuation of $183 billion. Forecasts: $20-26 billion ARR in 2026, $70 billion in 2028. Growth driven by B2B sales: 80% from enterprise, partnerships with AWS and Google bring billions.
Potential Challenges and Ethical Aspects
Despite success, Anthropic faces challenges: competition, regulations (e.g., AI Act in EU), and criticism for a "too conservative" approach. However, their focus on safety is an advantage in an era of growing AI concerns.
