proof of concept (PoC)

basicwidespread

A small, fast, and cheap experiment that shows whether an idea works in practice before investing significant money and time.

In plain terms

A proof of concept is like baking only half a batch of a new cookie recipe at home before committing to a seventy-person wedding. The goal is not for it to look beautiful or for everyone to get some, but to find out whether the dough holds together at all.

Companies do the same with AI. Before rolling out a system across the entire customer service department, they test it on a small scale over a few weeks, with a narrow task, limited data, and a few people. The question at this stage is whether the tool can do what is expected of it.

A PoC is therefore not a finished product, but a decision-support experiment. At the end, three things can happen: they proceed, modify the idea, or drop it. It is also a good result if it turns out the idea does not work, because this was discovered cheaply.

How it works

They formulate a single narrow question, for example: 'Can an AI agent answer half of incoming billing questions without human help?'
They predefine what counts as success: a measurable threshold (accuracy, time saved, cost) and a deadline, typically a few weeks.
They assemble a stripped-down version with a small amount of real data. Little attention is paid to design or integration with other systems at this stage, but data protection must be observed even when working with real data.
They run it, measure the result and compare it with the pre-set threshold, noting errors and surprises as well.
They decide: a larger pilot run in a real environment can proceed, the idea needs to be adapted, or it must be stopped.

An everyday example

At your workplace, you and two colleagues are asked to evaluate an agent's work for two weeks. The agent selects from last year's incoming emails and writes draft responses. Nothing goes out to anyone in the live environment; you only indicate which responses are usable and which are erroneous. Management decides from this whether to launch a limited live trial (pilot).

Who is affected

entrepreneur, executiveThis is how you can decide with little money whether to invest seriously in an AI solution or if only the vendor's presentation was convincing.

employeeYou will often be the tester, and your feedback determines whether the tool eventually becomes part of your daily work. → Work & HR

developerYou must quickly assemble the experimental version and then explain why it cannot be deployed as-is. → Code

A common misconception

MythIf the PoC succeeded, the system is practically ready; it just needs to be turned on for everyone.

In realityA PoC only proves that the idea could work. The larger part of the work, namely reliability, security, legal compliance, integration with existing systems, and training people, comes only afterward.

Limits and risks

Experiments typically run on curated, clean data under ideal conditions, so results may be weaker in real-world use.
Many AI experiments never reach live deployment. In English, this state is often called "pilot purgatory," or the purgatory of experiments.
If you do not set the success metric in advance, almost any result can be framed as a success afterward.
Only rough conclusions can be drawn from a PoC regarding the cost and business viability of scaling the system; this is revealed by the pilot and detailed business calculations.

Similar, but not the same

Prototype – A prototype shows how the solution will look and function, while a proof of concept (PoC) only demonstrates whether it is feasible at all.
pilot projekt – A pilot is a limited-scale deployment running in a real environment with real users, typically following a successful PoC.
minimum viable product (MVP) – An MVP is a product with limited capabilities released to real users to gather market feedback; a PoC, by contrast, is a closed experiment not intended for the market.

A brief history

The term already appeared in American technical and government texts in the late 1960s, where it meant a theoretical justification before a costly development. From the 1980s, it spread more widely in engineering practice, pharmaceutical research, then in the software industry and business life.

Where things stand

At the end of 2026, a PoC is the usual first step in AI implementations, and most larger organizations run one. The main question today is how to turn many successful experiments into a system that actually works in production and pays back.
