Anthropic CFO says Claude Code writes over 90% of internal code, while hiring keeps accelerating

Finance reports once hours now finish in 30 minutes

Anthropic’s CFO Krishna Rao says more than 90% of the company’s internal code is generated by its agentic AI tool, Claude Code. He adds that the company uses dozens of specialized AI workflows to automate finance and enterprise operations, shrinking tasks that used to take hours—like revenue and compute utilization reporting—into roughly 30 minutes. Even then, AI typically produces 90–95% of outputs before human review, allowing employees to focus on judgment, strategy, and oversight while hiring accelerates.
