November in detail
AI Security SummitBy dcyphr.®
An expert day by ERNW and dcyphr.® on the security of AI systems: four talks, four round tables, 8:30 am to 5 pm – prompt injection, unsupervised agents, model supply chains, governance. For everyone who has to answer for AI, not just roll it out. Small, dense, no exhibition hall. In German.
Web Summit
Europe's largest tech conference: 70,000+ attendees, startups, investors and corporates from around the world at MEO Arena and FIL. For market overview and the big keynotes – plan your meetings in advance if you want to network with purpose.
MEDICA
The world's largest medical technology fair – and by now one of the densest AI fairs of all: diagnostics, imaging, surgical robotics, digital health. Anyone implementing AI in regulated industries learns here how approval and innovation go together.
Formnext
The leading fair for additive manufacturing, around 800 exhibitors. AI lives here in part optimisation, process monitoring and quality assurance – physical AI in the literal sense, layer by layer.
Microsoft Ignite
Microsoft's annual conference for IT and business: Copilot, Azure AI, agents in everyday Microsoft 365. Everything that lands in mid-sized companies' offices in 2027 is shown here first – keynotes and many sessions free to stream.
Slush
Europe's founder and investor gathering in the dark of the Finnish November – small enough for real conversations, big enough for the key funds. For corporate venture and innovation teams the most productive date of the month.
AICon Industry MannheimBy dcyphr.®
Us again – what a coincidence. The industry edition of AICon answers the one question most AI projects fail at: how does AI get from the presentation into production? Industrial AI, robotics and intelligent automation with real use cases – together with the City of Mannheim and NEXT MANNHEIM, motto “experience AI live”.
SPS – Smart Production Solutions
The leading automation fair with industrial AI as its 2026 focus: around 1,200 exhibitors show AI where it actually sits in the factory – in controllers, drives and software. The ideal follow-up to AICon Industry.
AWS re:Invent
The world's largest cloud conference and the place where AWS lays out its AI roadmap – Bedrock, agents, custom chips. If you build on AWS, this is where your 2027 decisions come from; for everyone else it sets the benchmark.

Frequently asked questions about conference November
Why are so many tech conferences held in November?
Because the business year is ending: vendors present their annual launches (Ignite, re:Invent), investors meet founders before the budget round (Web Summit, Slush), and industry plans the next year (SPS). Travel in November and you see twelve months of progress in four weeks.
Which AI conferences take place in Germany in November 2026?
The AI Security Summit on 5 November at ERNW in Heidelberg, MEDICA from 16 to 19 November in Düsseldorf, Formnext from 17 to 20 November in Frankfurt, AICon Industry Mannheim on 19 November at the m:con Rosengarten and SPS from 24 to 26 November in Nuremberg.
Web Summit or Slush – which is more relevant?
Web Summit is bigger and broader (70,000+ attendees, all industries), Slush smaller and denser – founders and investors among themselves. Slush for startups and corporate venture teams, Web Summit for market overview and media.
Can I follow Microsoft Ignite and AWS re:Invent online?
Yes, both stream keynotes and a large part of the sessions for free; recordings stay available. Being on site pays off mainly for hands-on labs and conversations with the product teams.
