Typical AI cost underestimation, pilot to production

The Problem

AI cost data isn’t unit economics.

Horizontal FinOps tools show you totals. Dev observability tools show you traces. Neither tells the CFO whether each customer is actually profitable.

No per-customer attribution

Your vendor dashboards show spend by model or endpoint. Your CFO needs spend by customer, project, and agent. Nobody tracks that today.

No margin view

You know what you spent on tokens. You don't know how that compares to what you charged the customer. A lot of AI-first SaaS is running near-zero gross margin without realizing it.

No waste signal

Reruns, retry loops, oversized models. Together they add up to 40–60% of production LLM spend, all of it recoverable. Nobody surfaces that in dollar terms.

The Platform

Attribute. Measure. Optimize.

Everything a CFO and a VP Engineering need to answer the same question without contradicting each other: which of our customers is actually profitable?

Tagging SDK

Wrap your OpenAI, Anthropic, or Google client once. Every call inherits customer, project, and agent context automatically. Zero per-call code changes, zero added latency.

Margin Contribution Dashboard

Quadrant view of revenue vs margin per customer. Surface unprofitable customers, at-risk revenue, and margin trends in one screen. This is the CFO demo.

Agent Run Economics

Cost per agent run, cost distribution, expensive-run alerts. Prove which agents are cost-efficient and which are burning your margin on retries.

Rerun & Waste Detection

Identical prompt repetition, retry loops, prompt bloat. All surfaced as dollars saved, not error counts. Typical customer finds $20K to $50K per month of waste in month one.

Right-Sizing Recommendations

Where can you move workloads from frontier to smaller models without quality loss? We show you, with ROI math attached. Not just "try a smaller model."

LiteLLM Gateway Native

Route through LiteLLM, Bifrost, or Portkey? One line of config captures every provider behind the gateway. No SDK install required.

For AI-native teams

You can’t specialize what you can’t attribute.

Every AI-native SaaS is about to make the same call: which workloads move to smaller, specialized, or fine-tuned models? That decision needs per-workload cost, per-customer margin, and evidence that the frontier has stopped improving the task. That data is what CtrlSpend is built to produce.

Find the workloads worth specializing

Not every workload benefits from post-training. Attribution surfaces the volume, cost, and flat-frontier-improvement combo that actually justifies the engineering effort.

Model the ROI before you commit

A post-training program costs $1M to $2M per year at scale. Our right-sizing engine models expected savings against team and compute cost, so you know if the math works before you hire the team.

Insure against vendor lock-in

Every quarter, frontier labs raise prices, change terms, or restrict access. Attribution tells you which workloads to specialize first as a hedge, and which to leave on the frontier.

Integrations

Every provider,
and every gateway in front of them.

Native connectors for the frontier providers plus first-class gateway support. One integration with your existing LiteLLM setup covers your entire vendor list.
