About us

Welcome to the UK meetup for Neo4j, the world's leading graph database. We think graph databases are the future of data storage, because it's so expressive to model interesting connected data in a graph and super fast to query too.

We host regular events at our office in Southwark where we cover a variety of topics in talk based and hands on sessions.

Whether you're new to the world of graph databases or if you're an experienced graphista, everyone's welcome to join us for a drink afterwards and we pick up the tab. It's a great opportunity to network (see, graphs are everywhere!), and also to put those burning questions to the Neo4j engineering team over a pint.

Featured event

Context Graphs and AI Memory

Thu, May 7 · 6:00 PM BST

Neo4j UK, 182-194 Union Street, Union House, London, al, GB

We're excited to invite you to our next Meetup!

Join fellow graph enthusiasts, Neo4j developers, and members of the AI community as we explore how graphs, knowledge graphs, and context engineering can unlock smarter applications and better answers.

We look forward to connecting with the community to exchange ideas on graphs, tech, and AI - join the discussion!

Session 1:
Context Graphs for Explainable, Decision-Aware AI Agents
Andreas Kollegger, Developer Advocate - Neo4j

AI agents can follow prompts and use tools, but often lack the institutional context needed to explain why a decision is made. That reasoning: policies, precedents, and past outcomes are usually scattered across systems and human memory.
Context graphs capture this missing layer by modeling decision traces over time, including causality and context. By giving agents access to just enough historical and organizational knowledge, context graphs enable more explainable, consistent, and auditable decisions.

Session 2: tbd

Hack Night London
Wed, May 13 · 4:00 PM BST
Tessl, 210 Pentonville Rd, London N1 9JY, London, GB

## What's Hack Night?

Five hours. One room full of builders. Zero fluff. As many demos as we can.
Hack Night at Tessl is a London evening for people who would rather build than posture. You show up with an idea, find a team if you want one, spend a few focused hours shipping with a DJ in the background, and demo what you made before the night ends. Then we head to the pub.
When: May 13, 2026 | 4:00 PM - 8:45 PM BST Where: Tessl office, London

## Here's How It Works

4:00 PM - Doors Open
Check in, grab food, meet other builders, form groups, (or solo hack if you want) and decide what you're making.
4:30 PM - Opening Context
Quick welcome from the host and venue partner so everyone knows the flow for the night.
5:00 PM - Short Technical Remarks
If there are host or sponsor remarks, they stay short. The point is to get useful context, then get people building.
5:30 PM - Build Time
Heads down. Music on. Ship something. Use the time to test an idea, explore a tool, or finally build the thing you've been sitting on.
7:30 PM - Demo Time
Show what you made. Get feedback. See what everyone else shipped.
8:45 PM - Wrap Up
Final demos, shout-outs, and a clean finish to the night. And of course, Pub! We're heading to a pub nearby for a pint and a proper debrief. Come if you want to keep the conversation going.

NODES, the biggest community gathering dedicated to engineering better intelligence returns on November 12, 2026, for its eighth year.
Join thousands of developers and data and AI practitioners for this free, 24-hour conference to learn about the latest advancements in intelligent systems and gain insights from speakers who showcase their implementations, tools, and models.
The Call for Papers is open. Submit your talk in one of those three tracks by June 15:
AI Engineering: Generative AI, RAG, and Agents
Build software with AI. From architecting multi-agent systems to exploring new coding workflows, AI tools and techniques are evolving rapidly—and graphs play a central role. Learn from the latest research and real-world applications. Topics include knowledge graph construction from structured and unstructured data, context graphs and memory for more reliable AI systems, GraphRAG retrieval patterns, full-stack agentic strategies, and the libraries, tools, and services used to bring these systems into production.
Modern Applications: Libraries, Frameworks, and Platforms
Discover how developers build modern applications and AI-powered systems using graph databases alongside popular libraries, frameworks, and platforms. Learn how teams solve real-world problems across software stacks, deployments, integrations, and programming languages. Explore tools and practices tailored to different use cases that streamline development, improve the developer workflow, and accelerate the delivery of intelligent applications.
Data Intelligence: Knowledge Graphs, LLMs, and Fully Fledged Context
Explore how developers, data scientists, and AI builders unlock deeper intelligence from data. Learn how knowledge graphs and modern data workflows combine data engineering and domain expertise to build scalable pipelines, models, and knowledge structures that continuously improve outcomes. Sessions highlight practical techniques and real-world applications including GraphRAG, centrality, entity recognition, graph visualization, and scalable data integration.
We'll highlight some talks and speakers before the CFP deadline. Submit your abstract by May 20, 2026, to be considered.
