Audit
We analyse your current AI spend: volume, distribution across providers and models, and usage patterns. Results in 72 hours. Free if you start a three-month plan; otherwise between €1,500 and €3,500.
How it works
Four stages, from the first measurement to recurring savings. None of them interrupts your operation.
Where we fit
We sit between your applications and the providers you already use. Your requests go out the same way, your contracts stay where they are and you do not migrate your application.

No migration and no service interruption at any point.
The 4 phases of
A proposal built on your numbers
We present the achievable saving against your own consumption rather than generic estimates, along with the expected impact on response quality.
Integration
We integrate in under two weeks. You keep your provider, you do not migrate your application, and the service is never taken down.
Optimisation and reporting
Savings are recalibrated continuously as your patterns and market prices change. Every month you receive a report with your invoice compared.
Why it works
Diagnosis before promise
We measure your real spend and its composition first. Only then do we say what can be saved — using your numbers, not sector averages.
No application migration
Integration requires no application migration and no provider switch.
Verifiable savings every month
Each month you receive your invoice compared with and without e-ficient. If the saving is not in the report, it does not exist.
What about response quality
Saving money by lowering quality is not saving — it is moving the cost elsewhere. Quality is measured before we start and monitored afterwards. If a saving would require degrading it, we tell you and we do not apply it.
What happens to your data
We work in line with the GDPR. The audit runs on aggregated, anonymised consumption data: we care about how much and how you spend, not what your prompts contain.

Who it is for
Companies already running AI in production and watching the invoice grow without clear control: finance leadership that needs predictability, technology leadership that does not want to slow delivery, and procurement that needs to justify the spend.
Use case examples
Two situations we run into often, and the lever that fixes each one.
Data extraction from documents
A company processes thousands of invoices and delivery notes every month with the same large model for everything: read the document, classify it and pull four fields. Once measured, most of the spend turns out to sit in the simplest and most repeated task. Classification is routed to a small model, the large one is kept for the documents that resist it, and whatever is not urgent goes through batch pricing. The result is the same; the invoice is not.
Internal search over documentation
A team queries its own documentation through an assistant. Over time the prompt has grown: instructions, examples and whole documents travelling on every request, used or not. Cost is not growing because of the answers, it is growing because of the context sent again and again. The fixed part is separated out, cached and paid for once, and only the fragment that is needed is retrieved instead of the whole document.
Start by knowing how much you overspend
The initial audit returns a diagnosis within 72 hours and is free if you start a plan with a three-month commitment. Without that commitment it costs between €1,500 and €3,500.
Request an auditFrequently asked questions
How much can my company save?
The usual range is 30–60% of inference spend, but the specific figure depends on your consumption patterns. The audit confirms it within 72 hours, before you commit to anything.
What exactly is the audit, and what does it cost?
It is an analysis of your current AI spend: volume, distribution across providers and models, and where the avoidable cost sits. It is free if you start a plan with a three-month commitment; without that commitment it costs between €1,500 and €3,500 depending on the size of your operation.
Do I have to switch providers or migrate my application?
No. You keep your contracts and service levels, and you do not migrate your application.
What happens to response quality?
It is measured before we start and monitored afterwards. If an optimisation would degrade it, we tell you and it is not applied.
How do I know the saving is real?
Each month you receive a report with your invoice compared with and without e-ficient. If the saving is not in the report, it does not exist.
What kind of company is this for?
Companies already running AI in production whose invoice is growing without clear control. Below a certain spend volume the service does not pay for itself, and we will say so.
