Worth the trip if you are raising a pre-seed round in Berlin or investing at that stage.

Product People and Babbel host a German-language morning panel on what is left of the product manager's job once AI handles the execution: where judgement still decides outcomes and which calls cannot be delegated. Jon Freeman (Partner, Product People) moderates a panel with product leaders from Babbel, YourHero and Doctolib, followed by coffee and an hour of networking. Aimed at CPOs, CTOs and heads of product, engineering and growth.

Designer Friends Berlin host a long-form conversation with Bob Baxley, the design leader behind Apple's retail experience and later Pinterest and ThoughtSpot, on how Apple's approach still shapes the way the industry thinks about craft, teams and the relationship between design and engineering.

Merantix AI Campus, 13355 Berlin

The tenth edition of Merantix AI Campus's no-hierarchy gathering for software engineers, AI/ML practitioners and technologists. There is no preset schedule and no speaker list — the agenda is built on the spot by whoever turns up, whether they are training foundation models, running inference pipelines or scaling systems in production. Good for deep technical conversation rather than polished talks.

Merantix AI Campus, 13355 Berlin

An evening at Merantix AI Campus on running AI locally in healthcare settings — on-premise and on-device inference, what that unlocks for patient data that cannot leave the building, and where the clinical workflow actually absorbs it. Brings together founders, ML engineers and clinicians, which is a rarer mix than it sounds. Free.

Messe Berlin, 14055 Berlin

The world's leading trade fair for transport technology takes over the whole of Messe Berlin for four days. Increasingly a software and data event as much as a rolling-stock one: digital signalling, predictive maintenance, autonomous operation and passenger-facing platforms all have substantial programme space, alongside a startup and innovation area. Worth the day for anyone building mobility, IoT or industrial data products, not just the rail industry.

with Emmanuel Marill (Executive, OpenAI) · Isabelle Sonnenfeld (Strategic Advisor, Explicit Protocol)

Emmanuel Marill of OpenAI in conversation with Isabelle Sonnenfeld, Strategic Advisor at Explicit Protocol, on why experimentation is everywhere but impact at scale is rare — and what changes when AI moves from tools that help with individual tasks to agents that carry work across a whole process. Hosted by Merantix AI Campus for enterprise and scale-up operators.

KI Park e.V., 12107 Berlin

Berlin Expert Days returns for two days of deeply technical talks from working software engineers — architecture, JVM and platform topics alongside a now-substantial AI engineering track. Community-run and reliably free of vendor keynotes, which is why Berlin's senior engineers keep turning up. Two days, single city, no marketing.

w3.hub, 10963 Berlin

Circuit hosts a deliberately small Kreuzberg meetup for about fifty people who run Nous Research's Hermes models in real work — daily, wired into their own stack, pushed past what the documentation covers. Nobody explains what an agent is. The goal is to get Berlin's Hermes users into one room and work out how the city and Nous Research collaborate from here.

Fourth edition of a Berlin meetup on both halves of the security equation now that AI has changed them at once: attackers automating reconnaissance, phishing and exploit development at new scale, defenders shipping agents that triage alerts and hunt threats, and the models themselves becoming an attack surface that is being shipped into products before anyone has agreed how to secure it. Run by Startups.Berlin; venue shared with registered attendees.

An evening at deepset's Berlin HQ where open agents meet open tabular models, run by Haystack (the open-source AI orchestration framework) and Prior Labs (creators of TabPFN, an open-weight foundation model for tabular data). Sessions are shaped by what attendees are actually building, aimed at AI engineers building agentic systems and ML engineers building the models underneath them.
