In the previous meetup, we discussed a difficult question: **Will AI replace Scrum Masters and Agile Coaches?** This session builds on that conversation. Instead of focusing on what might disappear, we’ll focus on: **What will become more valuable.** 🧠 **What you’ll learn** We’ll explore the shift from: * Why facilitation and process knowledge are no longer enough * The shift from team-level focus to system-level thinking * How organizational design becomes a key capability * What skills will make you stand out in the coming years Grounded in Org Topologies™, we’ll look at: * Why many roles operate in **output-driven, incomplete setups** * The shift toward **outcome-oriented, complete mandates** * Why organizational design becomes a **core capability** * How AI amplifies this shift rather than causing it 🔑 **Core idea** The future is not about becoming a better Scrum Master. It’s about becoming someone who can: * see the organization as a system * identify structural constraints * redesign how work, learning, and decision-making happen 🎤 **Format** * \~30 min talk * \~30 min Q&A and discussion * \~30+ min Networking 👥 **Who this is for** * Scrum Masters & Agile Coaches seeking their next evolution * People struggling to create impact in their current setup * Leaders interested in system-level change * Anyone thinking about their next career step 💡 **Why join** Many people feel that “something is changing.” This session helps you **name the shift** — and position yourself within it. Btw: This meetup prepares the ground for a special session with the author of *10xOrg* in June.

Welcome to the PyData Berlin May meetup! We would like to welcome you all starting from 18:00. There will be food and drinks. The talks begin around 18.30 and the doors will close at 18:45. **Make sure to arrive on time!** Please provide your first and last name for the registration because this is required for the venue's entry policy. If you cannot attend, please cancel your spot so others are able to join as the space is limited. **Host**: **GetYourGuide** is excited to welcome you to this month's version of PyData. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* The Lineup for the evening **Talk 1: Text2SQL in the Wild — Agentic Workflows & Semantic Models on Customer Data** **Abstract**: Translating a business user's natural language question into a reliable SQL query has huge value for business analysts, but doing it accurately at scale, on messy enterprise data, for complex queries, is incredibly difficult. This talk walks through a production Text2SQL system built on four pillars: semantic models built on customer data, RAG-based semantic search, an agentic verification and correction loop for building the SQL, and an evaluation framework for the entire process. Raw schema information is not enough for text2sql to work. Rather, thorough documentation including business metrics, synonyms, and qualified example queries, are required. We'll cover how to automate this documentation pipeline by mining query logs, generating descriptions with LLMs, and organizing everything into a knowledge graph and vector search index. From there, we'll dive into the agentic flow that takes a user question and iteratively generates, validates, and fixes SQL against a live database. The agentic framework analyses syntax errors and execution results to help it fix the SQL. Participants will leave with practical takeaways on RAG architecture for structured data, agentic retry patterns, and how to think about evaluation for Text2SQL systems in production. **Speaker**: Oren Matar **Bio**: Oren Matar is a principal data scientist and algorithms developer, with a background in social sciences and Bayesian methods. He specializes in NLP and time series forecasting, as well as agentic methods for data retrieval and processing. **Talk 2: Interpreting and Communicating Statistical Models** **Abstract**: Extracting actionable insights from complex statistical models remains a challenge, as raw coefficients are often uninterpretable due to nonlinearity, interactions, or hierarchical structures. This talk introduces a unified framework for model interpretation based on the principles of the Marginal Effects project ([https://marginaleffects.com/](https://marginaleffects.com/)). We move away from internal model parameters toward quantities of interest, such as marginal effects and adjusted predictions that translate statistical output into the "natural language" of the data. We will demonstrate these concepts in Python using the Bambi interpret module, showcasing a seamless workflow for interpreting Bayesian models built on PyMC. The audience will learn how to use the four primary interpretative pillars: Predictions, Comparisons, Slopes, and Marginal Means to compute average marginal effects and visualize conditional relationships. By the end of this session, you will be equipped to turn sophisticated GLMs and multi-level models into clear, rigorous narratives that are easily communicated to stakeholders. **Speaker**: Juan Orduz **Bio**: Juan is a Mathematician (Ph.D. Humboldt Universität zu Berlin) and Principal Data Scientist at PyMC Labs. He is interested in interdisciplinary applications of mathematical methods. In particular, time series analysis, Bayesian methods, and causal inference. **Lightning talks** There will be slots for 2-3 Lightning Talks (3-5 Minutes for each) between the two main talks. Kindly let us know if you would like to present something :) \*\*\* NumFOCUS **Code of Conduct** THE SHORT VERSION Be kind to others. Do not insult or put down others. Behave professionally.

Let’s be honest: the traditional cultural sector often forces us to choose between our creative integrity and our financial survival. The myth of the "starving artist" or the "solitary genius" is a trap that keeps cultural workers in a constant state of precarity. But what if we could design our projects differently? What if we could build cultural businesses based on solidarity, cooperation, and radical sustainability? Join us on May 27th for an interactive, hands-on workshop co-hosted by ODBK and Travelling U. We will explore how to dismantle extractivist practices and design alternative business models that actually serve the creators. **What you will learn in this session:** * Beyond the Canvas: How to view system design and business models as part of your artistic medium. * Alternative Frameworks: An introduction to cooperative structures and the solidarity economy. * Redefining Value: How to measure the success of your cultural project using metrics of care, rather than just capitalist extraction. * Real-World Pathways: Tangible examples of cultural workers who have successfully subverted the system to gain economic sovereignty. **Who is this for?** Artists, cultural managers, creative freelancers, and social entrepreneurs in Berlin who are tired of the traditional hustle culture and want to explore sustainable, collective ways to structure their work. **About the Facilitator:** Oihane Amurrio is an artist, educator, and cultural entrepreneur based in Berlin. She specialises in designing alternative pedagogical models in the cultural sector and is the lead designer of the *Cooperative Cultural Entrepreneurship (CCE)* program at Travelling U.

**Move Capital. Move Talent. Move Africa.** Africa is the youngest continent on earth. By 2050, 1 in 5 people globally will be African. Yet African startups still receive less than 1% of global VC funding. What is the real problem? Is it time to tap into the estimated $95–100 billion USD in remittances sent by the diaspora? This Africa Day, in partnership with the Westerwelle Foundation, which has just published The German–Africa Investment Report, we will go deep into the gaps to explore : 📈 How Africa’s startup ecosystem is growing 🌍 Which New markets are rising, and how to pay attention to them 💡 Which segments pose the greatest returns outside of FinTech 🤝 How to take the best next step as an investor, proven by research. The event welcomes: Founders, Investors, Operators, the diaspora, and Institutional partners looking to make their moves into the African Market with intention. To our network members and partners who have been looking to make the move from remittances → to investment, from fragmented effort → to ecosystem building. This event is for you. Culminating from this event will be our delegation trip to #Nigeria and #Ghana in September in Collaboration with GITEX Nigeria and South Africa, and Namibia in November. Move Africa. #AfricaDay #AfricaRising #AfricanDiaspora #InvestInAfrica #AfricanInnovation #investment #funding # VC #Angelinvesting #African Excellence #Excellence #Leadership #FutureOfAfricaEvening Programme **SCHEDULE** 18:30 Arrival Networking reception Guests arrive. No job titles on badges — just names and country of origin. The room begins to know itself before the panel starts. 19:00 Opening Welcome & the diagnosis — 10 mins The host frames the evening in plain language. Not a speech — a provocation. Four sentences stating the diagnosis. Then the panel takes the stage. 19:10 Panel · 50 mins The conversation — moderated, flowing, unscripted Four panellists. One moderator. The conversation moves through the diagnosis naturally — from the wealth gap, to the talent drain, to the trust deficit, to the intention trap. No fixed questions. The moderator's job is to keep the room honest and the conversation moving toward one inevitable question: so what do we do about it tonight? 20:00 Panel · Open floor The room joins the conversation — 20 mins Not a Q&A. The moderator selects three or four people in the room — pre-identified — to add their perspective. Brief, pointed contributions that deepen the diagnosis rather than repeat it. The panel responds. The room feels heard. 20:20 Break Drinks — 20 mins The panel comes off stage and into the room. Guests speak directly with panellists. The conversation continues informally — which means it deepens.
