Buy the decision before the build.

Discovery is fixed at €18,000 and can end in no. Everything after it is quoted against evidence rather than a brief.

Recommended

Discovery

For teams who have a problem and a suspicion, not a spec.

€18,000

2–3 weeks Fixed. Not an estimate.

  • Walk away after it with a decision, not a dependency
  • Candidate approaches benchmarked on your own data
  • A costed architecture, and the case against building it
  • Feasibility spikes you keep, working, whatever you decide
Start with discovery

Then

Build

For a decision already made and a system that has to hold in production.

€60,000 — €250,000

From 6–10 weeks Quoted after discovery, never before.

  • Live staging from week two — no reveal at the end
  • Evaluation harness and traces ship with the system
  • Your engineers pair with ours from the first week
  • Single system at the lower end, multi-quarter platform at the upper
Scope a build

After

Retainer

For systems in production that need someone watching the drift.

Monthly, quoted

Rolling, cancel anytime Optional. Thirty days of warranty come free.

  • No lock-in: the code, evals and docs run without us
  • Drift monitoring against the suite we left behind
  • Incremental work billed against a monthly envelope
  • Escalation path for the system we built, not a generic SLA

What each one delivers Compare the three See the capabilities

Method

One number is fixed. The other is earned.

Discovery costs €18,000 whatever it finds. That price is fixed because the deliverable is, and because the decision it produces has to be worth buying on its own — including when it tells you to stop.

A build price quoted before that work is fiction. Padded, it costs you money you did not need to spend. Sharp, it becomes a renegotiation once you are committed. Quoted after, it is scoped against your data.

What protects you if this goes wrong.

Discovery can end in no
It has, and we wrote it down. Two to three weeks is the cheapest way to find out you were about to build the wrong thing.
Fixed price on the fixed part
Discovery does not overrun onto your invoice. If we estimated it wrong, that is our margin, not your budget.
Nothing is revealed at the end
Staging goes live in week two and stays live. Scope is reviewed fortnightly against what is actually running.
No lock-in, by construction
The code, the evaluation suite and the documentation are yours and run without us. The retainer is rolling, not a condition of handover.
