Who runs Anthropic
Claude is used by software companies, financial services, legal and professional services, healthcare and enterprises deploying AI assistants and agents. Usage spans the Claude apps for knowledge work, Claude Code for software development and the API for building products.
Who to contact
The CTO, Head of AI or Chief AI Officer leads strategy. Engineering and ML platform teams run API usage, and security, legal and compliance teams review data handling. For workforce rollouts, the CIO and business unit leaders are involved.
When Anthropic accounts are ready to buy
Scaling from pilot to production, adding AI coding tools for engineering teams, building agents, and governance or cost reviews create demand for surrounding tools and services.
How to segment and approach
Segment by access route (direct API, Amazon Bedrock or Google Vertex AI), by industry and by whether the account also uses other model providers. Bedrock and Vertex users are tied to those clouds and buy through their marketplaces.
Focus on reliability, evaluation, security and cost control for AI applications, with technical detail engineers can check.
