Anthropic
Claude and Claude Code for internal engineering and research
Anthropic engineers and researchers reported a 50% productivity boost from Claude
Problem
Debugging and understanding unfamiliar code consumed engineering time. Some exploratory work was too expensive to complete manually.
Approach
Engineers and researchers used Claude to debug code and understand codebases. Anthropic examined internal Claude Code usage alongside an August 2025 employee survey. Staff generally continued to supervise and validate the work.
Results
Takeaway
The productivity estimate came from employee reports rather than a controlled comparison. Frequent use still involved human review.
