A keynote speaker gives the main talk that opens or closes an event or session, and sets its theme for everyone in the room. Their job is to shift how a big audience thinks about one subject, so the rest of the event has a shared starting point and a shared language.
I speak at events, so I get asked this a lot, usually by someone who's been handed an event to organise and a line on the agenda that just says "keynote". Here's what the role involves, how it differs from the other sessions on a programme, and how to decide whether your event needs one.
What a keynote speaker does on the day
The keynote is the talk the whole event gathers for. It usually opens the day or a session, sometimes it closes it, and its job is to set the theme everyone else builds on.
A good keynote is built to shift thinking in a big room. In a short slot it can calm fears, puncture hype, show what's realistic and give everyone a shared language for the conversations that follow. That last part matters more than people expect. When every attendee has heard the same talk, the coffee-break chats, the breakouts and the panels all start from the same place.
What a keynote won't do is teach people a new skill they can use straight away. It opens the door; it doesn't walk them through it. If you need people to leave able to do something new, you need a different format alongside it.
How a keynote compares with other sessions
Most event programmes mix a few formats. Here's how they differ in what they're for.
| Keynote | Workshop | Panel | |
|---|---|---|---|
| Goal | Shift how the whole room thinks about one subject | Help a smaller group build or practise something on their own tasks | Bring several viewpoints on one topic into one conversation |
| Audience | Everyone at the event, together | A smaller group | Usually the whole room or a session track |
| Voices | One speaker | One facilitator working with the group | Several speakers and a host |
| What people leave with | A shared view and a shared language | Prompts, templates or a small workflow they built themselves | A sense of where opinions agree and differ |
A workshop is hands-on. A smaller group works on real tasks, tries tools, makes mistakes in a safe place and leaves with something they built themselves. The trade-off is reach: a workshop can't serve a hall of hundreds the way a keynote can.
Many events do both: a keynote first, then a breakout workshop. The keynote gets everyone thinking the same way, and the workshop turns that thinking into something people can use.
Deciding whether your event needs one
These are the questions I'd work through before booking anyone.
- Picture Monday morning. Decide what you'd like attendees doing when they're back at work, and the right format usually becomes obvious. A new way of thinking points to a keynote; a new skill points to a workshop.
- Look at the room. A keynote is made for a large audience in one shared moment. If the group is small and wants to get their hands dirty, a workshop will serve them better.
- Check the time you've got. A short slot suits a keynote. Hands-on work needs room for people to try things and get stuck.
- Choose one voice or many. If you want a single clear point of view to frame the event, book a keynote speaker. If you want debate, run a panel.
- Brief the speaker. Tell them who's in the room, what's worrying them and what you want them doing afterwards, so the talk fits your audience and not a generic one.

A worked example: the AI keynote
AI is a good example because it's a subject where a room full of people often hold very different views. Some are worried about their jobs, some are tired of the hype, and some are already using tools and want to know what's next.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Book an AI keynote when you want a large audience to rethink what AI means for their work in a short, shared moment. Book an AI workshop when a smaller group needs to leave having built or practised something on their own tasks.
In practice, an AI keynote for leadership teams, founders or senior marketers would cover what's realistic now and what isn't, where AI changes the way their teams work, and which questions they should be asking next. That's the audience I'm usually brought in to speak to: people steering a business through growth, change and the practical impact of AI. The aim isn't to teach a tool. It's to give the room a clear, shared view, so the decisions that follow are better ones. You can see how I approach this on my speaking page.
Plain advice for event organisers
Start with the outcome, not the speaker. If you want a whole room to see a subject differently and talk about it in the same terms, book a keynote and put it at the start. If you want people to leave able to do something new, add a workshop after it. And whoever you book, brief them on your audience, because a keynote that fits the room is the one people are still talking about the next day.
If you're planning an event and want your audience to come away using AI with confidence, this is what I do all day. I run AI training and workshops for teams, and help businesses with AI enablement and workflow automation, so the busywork runs itself and people get time back. Most of that work is with SaaS marketing teams and small businesses. Here's how we can work together.
Frequently asked questions
What does a keynote speaker do?
A keynote speaker gives the main talk that opens or closes an event or session and sets its theme. Their job is to shift how a big audience thinks about one subject and give everyone a shared language for the rest of the event.
What's the difference between a keynote and a workshop?
A keynote shifts thinking in a big room. A workshop is hands-on: a smaller group works on real tasks and leaves with prompts, templates or a small workflow they built themselves.
Where does a keynote sit in an event programme?
Usually at the start of the event or a session, and sometimes at the close. It's the main talk, so it sets the theme everyone else builds on.
Can an event have a keynote and a workshop?
Yes. Many events do both: a keynote first to get everyone thinking the same way, then a breakout workshop where a smaller group puts it into practice.
How do I know if my event needs a keynote?
Decide what you'd like attendees doing on Monday morning. If it's thinking differently about a subject, book a keynote. If it's using a new skill, plan a workshop.
