The Semantic Layer London

A casual London meetup for people building knowledge graphs for enterprise AI and those starting to suspect they'll need to, after a VectorRAG demo didn't survive contact with production.
You know the moment. The LLM fabricates confidently. Retrieval misses the obvious. Governance is impossible. The demo shipped; the rollout stalled.
This is the room for the people solving that, or trying to.
Come for:
Shop talk with CTO's, Heads of Data and engineers building GraphRAG, ontologies, and semantic layers
Honest conversations about what works and what doesn't
Peers who've hit the same walls
Free to attend. No dress code. Grab food and drinks at the bar.
