A Summit built by builders
More than a GenAI event
This year’s GenAI Summit dives into agentic systems — tools that plan, reason, and operate with increasing autonomy. From cutting-edge research to real-world case studies, the GenAI Summit is an opportunity to explore the next frontier of AI. What sets us apart?
We’re not event planners — we’re builders.
This summit is brought to life by the same team that designs and ships AI products every day.

Our manifesto
Why we build the GenAI Summit
We’re not event organizers—we’re builders, researchers, and founders shaping GenAI in practice. This summit is the space we needed: for serious conversations, real GenAI adoption, and regional innovation. Built by and for people creating the future of AI—especially in Southern Europe, the Middle East, and Africa.
It’s not a stage. It’s a working session.
The best of the 3rd GenAI Summit — before we take on the 4th
