Register: [https://events.neo4j.com/graphsummit-nordics-2026](https://events.neo4j.com/graphsummit-nordics-2026) Graphs + AI: Transform Your Data Into Knowledge Join us for a full day of insights, hands-on learning and real-world examples showing how graph technology transforms disconnected data into actionable knowledge that powers intelligent AI systems. Agenda Highlights: **Graphs + AI: Transform Your Data into Knowledge** *Emil Eifrem, CEO, Neo4j* Join us as Neo4j's **Emil Eifrem** explains how graph reveals the natural connections in your business data and provides the context AI needs to deliver real results. See how leading organizations turn enterprise knowledge into competitive advantage, powering intelligent decisions and driving business transformation. **A new AI based Graph Visualization tool: Financial Graph network for non-graph experts** *Fayçal Riad Hamou, Tech Lead - Financial Crime Prevention Services, DNB* Understanding a financial graph network structure is a complex task. We introduce a new AI‑based graph visualization tool designed to make financial network analysis accessible to non‑graph experts. The tool enables users to explore relationships, detect patterns, and identify risks without requiring prior knowledge of graph theory. The approach lowers the barrier to advanced financial network analysis while supporting faster and more informed decision‑making **Capgemini and AstraZeneca: Graph Implementation in Action** *Johan Müllern-Aspegren, Emerging Tech Lead, Applied Innovation Exchange Nordics and Core Member of AI Futures Lab, Capgemini* **From Fragmented Data to Holistic Insight: A Graph-Based Approach to Supply Chain Management** *Alexander Hegermann Lauritsen, Data Scientist - AI & Digital Accelerator, Danfoss Group Digital & IT* Modern supply chains are complex, multi-layered networks, yet fragmented systems often limit visibility, slow reactions to disruption, and make change hard to assess. In this talk, we share our journey to building a 360-degree, graph-based view of our end-to-end supply chain (SCM 360) using Neo4j, enabling impact analysis, risk propagation, traceability, and scenario exploration. We conclude with key lessons learned and what it takes to move from analytical insight to production-ready supply chain intelligence. **Neo4j Product Vision & Roadmap** *Ivan Zoratti, Vice President - Product Management, Neo4j* An insider look at the latest Neo4j innovations enabling relationship-driven intelligence at scale. Learn about new features and enhancements that make Neo4j essential for developers building interconnected data apps and AI.

**Ninth dbt Meetup in Copenhagen** The next Meetup is just around the corner! This time, we’re trying a new format: instead of three shorter presentations, we’ll feature two sessions — each with more time for deeper insights and discussion. The overarching theme for the evening is AI agents in analytics engineering and how they’re reshaping development with dbt. **Event Details** * **Date:** Wednesday, 11th of March 2026 * **Organizer:** Intellishore * **Venue Host:** Veo, Rovsingsgade 68, 2100 Copenhagen **Agenda & Speakers** **17:30** – Kick off the evening by networking over drinks and snacks **17:45** – Event introduction and welcome **18:00**–**19:30** – 💬 Speaker Sessions 1. **Building a dbt Data Vault That Scales With AI** **Speaker:** Frederik Juhl Pedersen (Senior Analytics Engineer at Veo) Most dbt projects slow down as they grow — naming drifts, reviews pile up, onboarding drags. At Veo, we rebuilt our platform as a 5-layer Data Vault with AutomateDV, strict naming, and deterministic patterns. The payoff: AI agents generate production-ready models from specs, and swapping an ingestion tool only affects one layer. This session shares the key architecture decisions, tradeoffs, and how standardization turned AI into a force multiplier. 2. **Agentic development with dbt Fusion and Databricks** **Speaker:** Nina Anderson (Solution Engineer at dbt Labs) In this talk, we’ll explore agentic development with dbt Fusion, the dbt MCP server, and Databricks, showing how the technologies combine to build, test, and reason over analytics workflows autonomously and safely. **19:30** – 🍕 Let's eat. Enjoy pizzas and great conversations **20:30** – Wrap-up **To attend, please read the Health and Safety Policy and Terms of Participation: [https://www.getdbt.com/legal/health-and-safety-policy](https://www.getdbt.com/legal/health-and-safety-policy)** ➡️ **Join the dbt Slack community**: [https://www.getdbt.com/community/](https://www.getdbt.com/community/) For the best Meetup experience, join the **#local-denmark** channel in dbt Slack: [https://slack.getdbt.com/](https://slack.getdbt.com/)

Welcome to this CopenhagenR spring get-together, which will be half a relaxed presentation on useful but unorthodox applications of R, and half an opportunity to connect and chat with fellow R users over coffee and cake, or a beer! **When?** Thursday, 12 March 2026 * **17:30** – Doors open * **18:00** – *Useful applications of R*, presentation by R.M., begins * **18:30** – Connect and chat with fellow R users. There will be coffee, beer, cake, and snacks * **20:00** – No more cake **Where?** PROSA København, room PASCAL Vester Farimagsgade 37A 1606 København **What?** Join us for a CopenhagenR meetup, whether you're new to R or a seasoned pro! This CopenhagenR spring get-together includes a presentation on *Useful applications of R* by **R.M.** **Presentation: Useful applications of R** With R jobs being so difficult to obtain and so poorly compensated, I mostly apply R to the much more useful pursuit of making my life pleasant and easy. I present some short, practical uses of R, such as studying patterns in neti pot usage so I can breathe more easily, understanding my employer-provided private health insurance plan so I can figure out how much of a scam it is, and correcting predictably erroneous payslips so I can pay my taxes.

In this talk, we will explore how to integrate AI into real-world C# projects, using Microsoft's latest AI Framework called Microsoft Agent Framework. We will start with a zero-to-first prompt walkthrough on how to get started and then move to chat, tools, structured output, and working with RAG. The event will be held at Twoday in Nordhavn.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
