Olumia is the intelligence layer for AI coding spend. Companies run multiple AI code assistants (GitHub Copilot, Cursor, Claude, OpenAI, and more), each billing differently, and nobody can predict the bill. Olumia connects read-only to every vendor and shows true cost per developer and per merged PR, finds idle seats and duplicate licenses to reclaim, and forecasts next quarter's bill with overrun alerts before the invoice, not after. No code access, no prompts read, so security review is fast. Costs under 2% of the spend it governs, while up to 40% of that spend is typically recoverable. Live at olumia.dev with a self-serve demo.
