LLM CFO is managed AI cost optimization for engineering teams spending $20K+/month on LLMs. We audit your OpenAI, Anthropic, Bedrock, Vertex AI, and Azure OpenAI spend, implement the fixes, and reconcile every dollar against your raw provider invoices. You only pay on the savings we deliver.
We're an early-stage service taking our first cohort. These are targets sourced from public benchmarks and our own engineering work — not customer claims.
Architecture-dependent. Confirmed against your invoices at audit.
Kickoff → first reconciled provider invoice.
Every change A/B tested 7 days minimum. Auto-rollback on regression.
Free. No savings, no fee — performance pricing.
Most engagements combine three or four of these. The audit tells us which dominate your spend surface.
Classify each request and route to the cheapest model that passes your quality bar. Reasoning goes to flagships; extraction and classification go to small fast models.

20–40%of lever scopeAudit system prompts for redundancy. Deduplicate examples. Compress retrieved context with LLMLingua-style techniques. Every change A/B tested.
15–30%of lever scopeRoute background jobs to batch endpoints (up to 50% discount) with SLO-aware queueing for anything time-sensitive.
