What an engagement costs

Three ways to start, priced so you can tell in ten seconds whether we are in your range. Every engagement begins with the review — we would rather charge you a small amount to tell you the truth than a large amount to build the wrong thing.

AI workflow review

€1,200 fixed

A written assessment, not a meeting.

We go through your operations and return a document naming the three workflows worth automating first, what each would take to build, what it would cost, and which ones we would refuse and why.

  • Three workflows named, scoped and costed
  • Architecture sketch for the first one
  • The workflows we would not automate, and why
  • Delivered within ten working days
  • Credited in full against a build started within 60 days
Most engagements start here

Proof of value

€9,500 from

One workflow, in production, with the evals attached.

We build the highest-value workflow from the review against your own data and put it in front of real users. You end with a system that runs, and the measurements that say how well.

  • Everything in the review
  • One agentic or retrieval workflow, built and deployed
  • Grounded in your data, with sources on every answer
  • An eval suite and a baseline you keep
  • Guardrails, cost telemetry and observability
  • Your infrastructure or ours, your choice
  • 50% on signature, 50% on go-live

Fractional AI engineering

€5,900 per month, from

Two days a week of senior AI engineering.

For teams with more AI work than one project. A standing commitment, the same engineer each week, working inside your repositories and your review process.

  • Everything in proof of value
  • Two days a week, same engineer, CET overlap
  • Direct access — no account manager in between
  • Model and provider strategy, not just implementation
  • Your team is trained as we go, not left with a black box
  • Annual prepayment: two months free
  • One month notice, and a written data-export and exit clause

Prices exclude VAT and are quoted in euros; we invoice in EUR, USD or CHF. Model and infrastructure costs are billed at cost with no markup. We contract from Serbia, work in Central European time, and sign your NDA and master agreement.

Questions people ask before booking

Why publish prices when almost nobody else does?
Because the alternative wastes your time and ours. If these numbers are far outside your range you will know in ten seconds instead of after two calls, and if they are not, the conversation starts at the actual work.
What if we only need the review?
That is a normal outcome and it is priced to stand alone. You keep the document, including the parts that say a workflow is not worth automating. If you go on to build with us within 60 days, the fee comes off the build.
Is a one-person-led shop a risk?
It is a fair question and we answer it in the contract rather than with a discount: a written data-export clause, your infrastructure if you prefer it, your repositories, and your team trained as the work proceeds. Nothing we build should be hostage to us.
What is not included?
Model and infrastructure costs are yours and billed at cost — we do not mark up tokens. Anything outside the agreed workflow is a separate, separately priced piece of work.
