AI startup Anthropic is dramatically expanding its international workforce and launching upgraded large language models to secure its position as a leading provider for worldwide enterprise adoption amid surging demand.
AI startup Anthropic is aggressively accelerating its enterprise growth strategy, driven by soaring international demand for its Claude large language models (LLMs). The company is planning a fivefold increase in its customer support staff and a tripling of its international workforce this year to better serve a rapidly expanding global client base. Over the past two years, Anthropic’s business customers have surged from fewer than 1,000 to more than 300,000 worldwide, according to company announcements. This expansion is underscored by the company’s growing presence in sectors ranging from financial services in London to manufacturing in Tokyo, where its AI models are increasingly embedded into mission-critical operations.
Anthropic’s international hiring spree includes adding over 100 new roles across key European hubs in Dublin, London, and a research-centric office in Zurich. It is also preparing to open new European offices and its first Asian office in Tokyo within the coming year. The global expansion is being led by Chris Ciauri, a seasoned enterprise executive recently appointed as Managing Director of International. Ciauri’s leadership aims to establish the necessary infrastructure and partnerships to support enterprise adoption in regions where nearly 80% of Claude’s usage now occurs, with particularly high per-capita adoption rates in countries such as South Korea, Australia, and Singapore.
In parallel with its workforce expansion, Anthropic has launched Claude Sonnet 4.5, an upgraded iteration of its flagship LLM designed to enhance employee productivity across various enterprise functions. This new model boasts improved capabilities in software coding, scientific reasoning, and financial tasks. Internal tests have demonstrated that Claude 4.5 can autonomously generate a working web app and deliver sustained coding output far beyond previous versions. Additionally, the model features safer guardrails geared towards regulated industries, emphasising reliability and risk reduction in professional environments. Microsoft recently announced that it will integrate Anthropic’s Claude models into Microsoft 365 Copilot, further embedding Anthropic’s technology into mainstream enterprise workflows and complementing Microsoft’s existing AI offerings.
Anthropic’s product strategy reflects a long-term enterprise focus that prioritises consistent, reliable AI performance over flashy demos. The company distinguishes itself by aiming to combat the common issue of “AI slop”—AI-generated content that is of insufficient quality to be useful—by producing outputs that get users substantially closer to their goals, enabling meaningful productivity enhancements. Mike Krieger, Anthropic’s Chief Product Officer, highlighted in an interview that Claude Sonnet 4.5 can generate professional-quality Word, Excel, and PowerPoint documents, extending AI utility beyond just coding to broader enterprise productivity tasks.
However, Krieger acknowledged ongoing challenges around enterprise AI adoption, noting that without appropriate tooling and support, many organisations risk disillusionment as initial AI enthusiasm wanes due to poor adoption or marginal productivity benefits. Furthermore, he addressed concerns about AI’s potential to displace human jobs. While noting that human roles involving relationship-building, trust, critical analysis, and strategic thinking remain vital, he conceded that labour shifts driven by AI automation are “almost inevitable.” Anthropic’s approach, he said, involves designing tools that amplify uniquely human strengths in collaboration with AI rather than simply replacing human effort.
Enterprises are already reporting tangible improvements due to AI integration. For example, South Korea’s SK Telecom achieved a 34% increase in customer service quality, and the Commonwealth Bank of Australia halved customer scam losses through Claude-powered systems. In the United States, United Airlines used Claude to enhance personalised customer messaging and accelerate response times, illustrating the practical benefits of AI-driven customer experience improvements.
Anthropic’s rapid enterprise traction contrasts with sceptical industry reports citing low returns on AI investments by many organisations. Data from MIT suggested that despite massive injections of capital into generative AI, most companies are not yet seeing significant productivity gains. Anthropic aims to defy that trend by focusing on meaningful, scalable applications of AI in business environments, supported by expanding teams dedicated to embedding AI into tailored workflows.
The $183 billion-valued company, backed by investors including Alphabet and Amazon, is fast becoming a formidable competitor to AI giants like OpenAI, Microsoft, and Google. Its aggressive international hiring and product release plans signal a decisive push to establish Claude as a foundational AI tool for enterprises worldwide, balancing innovation with pragmatic performance and user enablement.
