We Let 40 Engineers Loose With Coding Agents. The Bill Was Brutal.

Your engineering team adopted Claude Code last month. Productivity went up. Then the bill came in. 340% increase. Nobody budgeted for this. Nobody even knew who spent what. The math that kills budgets A single coding agent session makes 50-200 API calls. Claude Sonnet 4 processes 100K+ context windows on every call. One developer running sessions all day burns $50-100. Scale that to 40 engineers and you hit$20K/month in unexpected AI spend. The root cause: raw API keys. No per-developer budgets
