What this list does not tell you
- Where anyone is based. Berlin is the city of the event, never of the person. We hold no address, and nobody here is being described as local.
- How to reach them. No contact details are held. The agenda link is the route.
- Everyone who qualifies. This is a seed, not a census: absence is not evidence that someone has not spoken in Berlin.
- Anything about talks still to come. Only past, published sessions are recorded — there is no upcoming schedule here.
Questions about booking a speaker in Berlin
- How many AI speakers have spoken in Berlin?
- 102, across 4 conferences we hold agendas for. That is the number with a checkable record, not an estimate, and it grows when we index another Berlin conference, not when more people sign up.
- Which conferences do they come from?
- WeAreDevelopers World Congress 2026, Rise of AI Conference 2026, PyData Berlin 2025, PyCon DE & PyData Berlin 2024. Each one links to its own page, and from there to the conference's published agenda.
- How do you know they actually spoke?
- Because the conference published it. 98 of the 104 talk records on this page carry the session title exactly as the agenda printed it; the other 6 come from events that list speakers without per-session titles, and those are shown as our own label rather than dressed up as a published one. Nobody self-reported and nobody paid to be here.
- Are these speakers based in Berlin?
- Not necessarily, and we do not claim it. The city belongs to the event, not the person. This page answers who has taken a stage in Berlin, which is the question that matters when you are booking one there.
- What do they speak about?
- Most represented on this page: LLM, Data engineering, Generative AI, Machine learning, NLP, AI infrastructure. Topics come from the talks themselves, not from a profile someone filled in.
- Are these international keynote speakers?
- Yes. The speakers listed here took keynote and practitioner stages at major international technology and AI conferences in Berlin (WeAreDevelopers World Congress 2026, Rise of AI Conference 2026, PyData Berlin 2025, PyCon DE & PyData Berlin 2024). Each listing proves their stage appearance with a direct link to the published conference agenda.
- Can I get their contact details or fee?
- No. We hold neither. Every entry links to the agenda page it came from, and that link is the route. It is also the honest limit of what a directory built from public agendas can tell you.
Hiring a speaker in Berlin?
