Company names are withheld on purpose.

### Legal — demand-letter rollout

Personal injury. AI-assisted demand letter generation. A Series E legal-AI platform, valued above $2 billion, deploying across 2,000+ law firms. Each firm has its own buying group: Managing Partner, Partners, Operations Director, and paralegals or case managers.

### Enterprise technology — adoption across 2,000+ employees

### Go-to-market — $10–50 million ARR

Sales, marketing, and customer success. High enthusiasm for AI among sellers, with low discipline. CRM data built for reporting rather than for reasoning.
