Choosing a provider

AI proof of concept development services

The purpose of a proof of concept is to find out, honestly and cheaply, whether an idea works. That puts a particular demand on the provider: they must be willing to tell you it does not work. A provider whose main interest is selling the full build has every reason to make results look better than they are.

This page explains how to choose a proof of concept provider and what a transparent engagement looks like.

Choose a provider who will say no

Ask a prospective provider how often their proofs of concept lead to a recommendation not to proceed. Some genuinely should. A provider who has never recommended stopping may be framing tests to succeed or interpreting results generously.

Agreeing the success criteria before any testing removes much of this risk, because results are judged against a standard set in advance.

Questions to ask a provider

Method

  • Will success criteria be agreed before testing?
  • How will the test set be chosen?
  • Will we see examples of failures?

Independence

  • Will we receive the prompts and test set?
  • Can another provider build the full version?
  • Is the proof of concept priced on its own?

Warning signs

  • Demo on vendor examples

    Says little about performance on your data.

  • Criteria set after results

    Makes almost any result look like success.

  • Proof of concept bundled with a full build

    Removes your chance to stop.

  • No failure examples

    Every AI system fails sometimes; hiding it is a red flag.

How the engagement runs

  1. Framing session

    One question, criteria and data needs agreed.

    Output: Test plan

  2. Data preparation

    Your team helps assemble and label examples.

    Output: Test set

  3. Testing

    Prototype run on the test set; results measured.

    Output: Results

  4. Review meeting

    Results, failures and recommendation discussed.

    Output: Decision

What you keep

Whatever the result, you should keep the test set, the prompts and settings used, and the results report. If the answer is go, these become the starting point for a pilot, whoever builds it. If the answer is stop, they document why, which is useful if the idea is raised again later or if AI capabilities change enough to justify a re-test.

Re-testing later

AI models improve and change. A task that failed a proof of concept may be worth re-testing later, using the same test set and criteria. Because the test set is kept, re-testing is quick and gives a fair comparison with the earlier result.

Help framing the question

Many AI ideas start broad: use AI for customer service, or for paperwork. A good provider helps narrow these into testable questions, choosing the part of the process where AI is most likely to help and easiest to measure. This framing session is often where the most value is created, because it turns enthusiasm into a clear experiment.

If several questions emerge, they can be ranked and tested one at a time.

Data handling during testing

Agree how test data will be shared, which AI provider will process it, whether it is anonymised and when it will be deleted. Proofs of concept use small datasets, which makes careful handling straightforward, but it still needs agreeing in writing before any data changes hands.

After a go decision

A go decision leads to a pilot: a properly built workflow with integrations, validation and review, run on live work alongside the current process. The proof of concept's test set, prompts and measurements give the pilot a strong start and a benchmark to check against, whoever builds it.

Questions about AI proof of concept development services

Will you recommend stopping if it does not work?

Yes. That is one of the main purposes of a proof of concept.

Do we keep the prompts and test set?

Yes, along with the results report.

Must we use you for the full build?

No. The proof of concept stands on its own.

Do we need to help prepare data?

Yes. Your team knows which examples are typical and which are difficult.

Will we see failures?

Yes, with examples grouped by type.

Can we re-test later?

Yes, using the same test set for a fair comparison.

Can you help turn a broad idea into a test?

Yes. Framing a narrow, testable question is the first step.

What comes after a successful proof of concept?

A pilot on live work with proper integrations and review steps.

How many examples are needed?

Enough to represent typical and difficult cases; we agree the number for each test.
