AI Platform & Model Engineering

Golden Dataset Builder

We construct a rigorously curated golden test set for your AI task with balanced coverage, expert labels, and adjudicated edge cases. It becomes the ground truth every eval and regression check runs against.

Why you need it — Without correct answers to compare against, you cannot trust any test result. This gives you one fixed yardstick to check every new version of your AI.
  • Free scoping assessment first
  • Inspected before it goes live
  • One-time no renewal
  • 1–3 days build time, once your material is in
Free first step

Get a free proposal for your business, in minutes

Tell us your business name and we email you what this service would do for it, what we need and the fixed price. No account, no payment.

We use your email only to send this and to answer you.

When you order: a full refund if you cancel before work starts, and if a delivery does not contain what this page lists, we fix it, rebuild it or refund that part.

What you get

  • Plan of which kinds of tasks the test set must cover
  • AI helps pick good examples from your own data
  • Experts write and check the correct answers
  • Agreed way to settle answers experts disagree on
  • Test set with saved versions you can update
  • Report showing which tasks the test set covers

How your order runs

  1. Questionnaire

    You answer a short questionnaire about your business, your goals and what this service needs.

  2. Five sample concepts

    We prepare five sample dashboards from your answers, each showing your numbers in a different way.

  3. You choose or mix

    Pick one, or tell us what to take from two of them.

  4. Upload your material

    Send what this service works from — files, data, access or material, depending on the service. We use only what you give us.

  5. We build it

    Our specialist AI team builds the complete service from your choice and your material.

  6. Quality inspector

    An automated inspector checks the work. Anything that fails is rebuilt before you see it.

  7. Delivered

    The finished work arrives in your dashboard, ready to use. Nothing renews.

The five samples usually arrive within minutes. Each service's build time is counted from the day your questionnaire and material are complete.

What we need from you

We use only what you give us — we never invent your details.

  • What task does your AI do?
  • Who are your experts?
  • What real data can we use?
  • What edge cases worry you?
  • Where do tests run?

Your data stays yours.

The promise, in plain words — and each part is built into how we work, not just written here.

Encrypted, per customer

Everything you send us is encrypted with keys that belong to your account alone.

Used only for your service

Your files and answers are used to build your service — never for another customer's work.

No outside AI without approval

Data you mark confidential is not sent to any outside AI service we have not approved. By default it is handled only by our own tools.

Delete everything, any time

From your account you can delete everything you sent us and everything built from it. Your keys are destroyed, so even backups become unreadable, and you get a deletion receipt. Only the invoice records that accounting law requires are kept.
