Fixed agenda, tightly scheduled slots, one talk after another: that's how a classic conference runs. A barcamp turns this principle on its head, because here the attendees decide themselves what gets discussed. The approach originally comes from the tech scene, but by now it works in all kinds of contexts, from internal company culture to customer communities. We'll show you how a barcamp runs, where its strengths lie, and what to watch out for when planning one.
What a barcamp actually is
A barcamp, also known as an "unconference," is an event with no fixed programme. Instead of pre-arranged talks, attendees bring their own topic ideas and decide together which sessions actually happen. The idea behind it is simple: everyone contributes something, whether that's a short talk, a discussion round, or a concrete question from their own day-to-day work.
The flow usually follows the same pattern. At the start, anyone who wants to offer a session pitches their topic in one or two sentences. These pitches then get slotted live into a plan, whether that's a whiteboard, a pinboard, or a digital tool, usually through a quick vote by the group. After that, several small rounds run at the same time in different rooms. Anyone who isn't getting anything out of a session is free to get up and switch to another one at any point, no justification needed. This rule is known as the "law of two feet." The day often wraps up with a short summary or an informal recap, where the key takeaways from the sessions get shared.
Barcamp isn't the only loose format
Spontaneous conversations in between the heart of every barcamp.
Anyone looking for an alternative to the classic conference quickly runs into related formats alongside the barcamp.
A similar format is the so-called "open space," which, unlike a barcamp, has a rough overarching theme. Within that frame, attendees then organise themselves into small groups.
Another format is the "world café." Here, several table groups discuss in parallel and switch seats after a set time, so ideas and perspectives keep mixing together.
The so-called "fishbowl discussion" also belongs to this family. Attendees sit in two circles of chairs, only the inner one speaks actively, while the outer one listens and can step in when needed.
For smaller groups, there's also "lean coffee." Topics get collected and prioritised at the start, then discussed in fixed time blocks.
| Format | Group size | Structure | Best for |
|---|---|---|---|
| Barcamp | 25 to 500 | Attendees set all topics themselves | Open knowledge exchange, community building |
| Open Space | medium to large | Overarching theme set, subgroups free | Idea generation around a focus topic |
| World Café | variabel | Table rounds with rotation mit Rotation | Broad input, idea collection |
| Fishbowl | 20 to 150 | Two circles of chairs, inner circle discusses | Controversial topics, range of opinions |
| Lean Coffee | up to 12 | Timed topic rounds | Small team meetings, retros |
What sets the barcamp apart from this list is that the entire agenda really does come from the attendees, and the format still works for large groups.
Where the format works especially well
For internal innovation and culture formats, a barcamp is often more effective than a classic town hall meeting when companies want to gather ideas across departments or strengthen an open feedback culture. Employees bring the topics that genuinely matter to them, instead of sitting through pre-set slides.
The format also works well for community and user events. Customer communities, user groups, or partner networks already want to exchange knowledge with each other, a barcamp simply gives that exchange some structure.
In HR, recruiting, and employer branding, an open structure signals modernity and genuine participation to the outside world. That fits well with recruiting events or internal training days, where real dialogue matters more than pure knowledge transfer.
For knowledge sharing and further education, the barcamp helps surface expertise that often goes unused, particularly in industries with widely distributed knowledge such as IT, education, or healthcare. Well-known examples include EduCamps or CareCamps.
The approach originated in the startup and tech scene, and it still fits there most naturally today: fast, informal rounds where like-minded people exchange ideas on current topics without much lead time.
Where a barcamp reaches its limits
As flexible as the approach is, it doesn't suit every occasion. If an event needs to deliver a clear, predefined learning goal or a consistent message, such as a product launch, a classic, curated conference is usually the better choice. The same applies if an audience would rather consume content than actively shape it, since that's exactly where the format's main advantage falls flat.
Why the format works
The best ideas often emerge in a relaxed atmosphere.
The biggest advantage lies in the relevance that comes from the group itself. There are no topics planned around assumed needs, the agenda comes directly from what actually interests the attendees. At the same time, the approach flattens hierarchies: whether someone's an intern or part of the leadership team, only the topic counts on the session board, not the title behind it, which encourages more open discussions.
Speakers also face a much lower prep burden, since sessions are deliberately kept informal. That lowers the barrier to offering something in the first place, and usually leads to stronger engagement and more networking, since everyone actively shapes the event instead of just listening. On top of that, a barcamp tends to stay noticeably cheaper than a classic conference, since there's no costly speaker booking involved and the setup requirements are lower.
What this means for your planning
Even though the content emerges spontaneously, a barcamp still needs structure behind the scenes: enough parallel rooms, clear facilitation for the pitching and voting round, and an audience that's genuinely willing to get actively involved. A barcamp runs on participation, not on passive consumption.
Smooth organisation in the background matters just as much. Registration, session allocation, and on-site communication shouldn't take more effort than necessary, so the energy stays with the content instead of leaking into logistics. This is exactly where a well-thought-out event tool like Sweap can support you with registration, communication, and on-site check-in, while you focus on the actual format.
Conclusion
A barcamp doesn't replace every conference, but it's a strong approach wherever genuine exchange, flat hierarchies, and attendee experience should take centre stage. Anyone open to uncertainty in the agenda usually gets more engaged attendees and more relevant content in return than a fully planned programme could deliver.
Frequently Asked Questions About Barcamp:
There's no fixed minimum, but from around 25 people onward, you usually get enough topic variety for several parallel sessions. For smaller groups, a format like lean coffee tends to work better.
That's completely normal and part of the format. Most topics only emerge during the pitching round itself, once attendees react to each other's ideas. Good facilitation helps give that first spark.
Yes, using digital whiteboards for session planning and separate virtual rooms for the parallel rounds carries the principle over well. The informal exchange between sessions tends to be harder to replicate online than in person, though.
Smaller rooms and the option to suggest topics anonymously or in writing noticeably lower the barrier. The "law of two feet" helps too, since nobody has to stay in a session that just isn't working for them.
