AI summary (citable)
An online course is cheap, flexible and good for basics, but weak at transferring to your real process. Inhouse AI training costs more per head but aligns to your data and roles. When a concrete process should run better afterwards, a hands-on format on your real case beats both. The choice depends on goal, data relevance and completion rate, not on list price.
1. The real question behind the format choice
"Inhouse or online" is usually asked as a cost question. The better question: how much transfer to your real process does the result need? An online course scales knowledge cheaply and broadly, inhouse training brings your role and data context, but neither automatically ends in application. That gap decides the return.
The cheapest course is expensive if no one finishes it and no one applies what they learned. – Tim Jamboula, Founder of Corporathon
2. What each format actually delivers
| Criterion | Online course | Inhouse AI training | Hands-on hackathon |
|---|---|---|---|
| Cost per head | low | medium to high | outcome-based, not per head |
| Relevance to your data | none | partial, on examples | direct, on real processes |
| Transfer to daily work | low without follow-up | medium | high, because you build immediately |
| Completion rate | often low | high, because scheduled | very high, output is required |
| Output | certificate | certificate plus context | working prototype |
| Scales for breadth | very well | limited | focused, not for mass |
3. The decision framework in four questions
- Breadth or depth? Broad basics for many favour the online course. Depth on a process favours inhouse or hackathon.
- Does the result need your real data? If yes, the pure online course is out.
- What is the realistic completion rate? If self-paced courses rarely get finished, a scheduled format is more honest.
- Should there be a usable result at the end? If yes, the hackathon is the direct path.
4. The hidden cost logic of completion rate
List price hides the completion rate. Factor it in and the comparison often flips: effective cost per completion, opportunity cost of self-study without application, context cost of missing data relevance, and result cost (no course ships a prototype). Corporathon deliberately shows no fixed prices yet.
5. A worked ROI example (model)
Illustrative model: fifty people get a 200 EUR online course, 10,000 EUR list cost. At a 30 percent completion rate, 15 people effectively learn, about 667 EUR per learner. A scheduled inhouse format at 90 percent completion teaches 45 people, cutting the effective per-head cost sharply. A hackathon is measured against the value of the built prototype instead. Not guarantees, not client figures.
6. Why transfer beats format
Breadth and application rarely sit in the same format. An online course is broad but low on application; a hackathon is high on application for a concrete case. If you want application, do not buy a pure knowledge format. Positions are schematic.
7. EU AI Act: what counts
Since 2 February 2025, Article 4 requires sufficient, role-based AI literacy. An online course documents attendance, inhouse adds context, a hackathon documents application. Each is a building block, none is an official certificate, none guarantees automatic compliance.
8. What to do next
For broad basics without data relevance, an online course is the cheap choice; watch the completion rate. For context-near knowledge on your roles, inhouse fits. When a concrete process should run better afterwards, the direct path is a hands-on hackathon, one week from first contact to prototype.

FAQ
Is inhouse training always better than an online course? No. For broad basics without data relevance an online course is cheaper and enough. Inhouse pays off when context, roles and real data matter, or when self-paced completion rates are low.
Why does the completion rate matter so much? It determines the effective cost per learner. A cheap course only a third finish often costs more per head than a scheduled format with high completion.
When is a hackathon worth it instead of both? When a concrete process should measurably improve afterwards and an owner carries the result forward. Then the hackathon delivers knowledge, application and an artifact in one step.
Is an online course enough for the EU AI Act? It can document attendance but is only a building block. Article 4 turns on the role- and context-appropriate adequacy of the overall program, which the company owns.
