**ESMT Insight Hour with Paul M. Achleitner** **Schedule:** 5:30 p.m. - Registration opens 6:00 p.m. - Welcome from host, ESMT Berlin 6:05 p.m. - Talk of Paul M. Achleitner 6:30 p.m. - Discussion and Q&A 7:00 p.m. - Networking, drinks and nibbles will be provided 8:30 p.m. - Close Experience used to accumulate slowly. Today, decisions travel instantly, legitimacy can evaporate overnight, and leaders operate under permanent public scrutiny. So how do you lead and stay legitimate in a world that no longer feels stable? In this ESMT Insight Hour, **[Paul M. Achleitner](https://www.linkedin.com/in/paul-achleitner/)** joins us for a moderated conversation on leadership, corporate legitimacy, and performance in times of geopolitical disruption, digital transparency, and shifting societal expectations. Drawing on more than four decades across Goldman Sachs, Allianz, Deutsche Bank, and multiple supervisory boards, and reflecting the themes of his recent book, *Accelerate Your Experience: Principles for Success in a Fluid World*, Achleitner proposes three interconnected dimensions of modern management: * **Legitimacy** – why companies must earn their place in society beyond financial performance * **Performance** – how sustained value creation requires focus, discipline, and strategic clarity * **Leadership** – what integrity, intellectual humility, and judgment mean in an era of permanent visibility Rather than offering prescriptions, he distills experience into principles on stakeholder dynamics, public attention, geopolitical disruption, AI, crisis management, and the realities of “muddling through.” The conversation will explore: * Why legitimacy has become the decisive constraint for corporations * How leaders balance long-term value creation with short-term scrutiny * What performance really means when underperformance becomes normalized * The evolving role of boards in turbulent environments * Whether experience can, in fact, be “accelerated” Join us for an hour of reflection on leadership under pressure and on what it takes to remain effective, credible, and resilient.

AI features are being shipped at a rapid speed, products are being "enhanced" with machine intelligence overnight, and the pressure to move fast has never been higher. But in the rush to innovate, some critical questions are getting buried: *Who's accountable when AI gets it wrong? How much should we hand over to automation and what do we silently lose when we do? And what are the risks we're not even seeing yet?* These aren't hypothetical concerns. They're live, urgent, and sitting inside the products we're building right now. **It's time to have the conversation that some teams are avoiding.** UXDX Berlin is back! Join us at the GetYourGuide office in Prenzlauer Berg, where we will tackle the theme that every designer, researcher, and engineer needs to reckon with: **"Designing Responsible AI: Trust, Autonomy & Hidden Risk"** **Why This Event Matters** The tools are powerful. The timelines are short. The consequences for users, for society, for trust in technology are long. If you're building products with AI, this isn't an optional conversation. It's the one you need to be in the room for. **Come ready to think. Come ready to question. Come ready to build better.** Thank you [GetYourGuide](https://www.getyourguide.com/) for supporting the event!

Hello fellow Symfonians, we are thrilled to announce the next user group meeting of the year, featuring two insightful talks that you **won't want to miss**! This time we are hosted by c-base (Rungestrasse 20 10179 Berlin). Come by and enjoy an evening of learning, networking, and socializing with fellow Symfony and PHP developers. **Agenda:** 18:30: Doors open 19:00: Welcome and Introduction 19:20: **Talk 1: "Maintainable Frontends for Symfony" by Daniela Berger** 19:50: Break & Snack 20:00: **Talk 2: "Why every CMS needs MCP" by Roland Golla** 20:40: Socializing **Talk Details:** **Talk 1: "Maintainable Frontends for Symfony" by Daniela Berger** In many web projects we find more backend devs than frontend devs, sometimes significantly so. This often leads to devs with little frontend experience being asked to do frontend development anyway, and they often end up shaping their frontends in ways that will make their lives unnecessarily hard. One common result are frontends that are functionally unmaintainable because each change - whether it is a new feature or a bugfix - requires implementing an exception to existing code, thus making the code increasingly and unnecessarily complex. This is especially upsetting because with a bit of experience it is possible to implement light-weight frontend components with equally elegant CSS and JavaScript that are easy to extend and to adapt to new requirements without digging oneself into a deeper hole with each PR. And since Symfony is making frontend development steadily more accessible to backend devs with Symfony US / Stimulus, this is a good time to take a closer look at \*how\* to structure these frontends. This talk aims to a) introduce core frontend concepts that backend devs might not be aware of, b) show best frontend practices both on the code level and on the architecture level, c) show a few common mistakes that can be found in inexpertly implemented frontends, and c) introduce tools that will make consistent frontend development easier. **Talk 2: "Why every CMS needs MCP" by Roland Golla** Your content team already works in ChatGPT, Claude, and Gemini. Yet the content still lands in the CMS backend manually, clumsily, slowly. MCP changes that. One sentence in chat becomes a published article. No copy pasting, no formatting, no clicking. And the content ranks. On Google, on ChatGPT, on Perplexity, on whatever comes next. Good content written by AI directly into the CMS goes live faster and gets found. I show you the MCP plugin for Sulu CMS: open source, built on Symfony, ready to deploy. But this is not about implementation. It is about the three questions every content team must ask: Why does every website need MCP? What does good AI content look like? And why is conversational content management better than anything you click together in a backend? MCP makes content creation as easy as chat. If you can write, you can publish. No CMS training, no workflow, no waiting. Live on stage: a complete workflow from idea in chat to published article in Sulu CMS. Everything open source on GitHub. Don't miss these insightful talks, engaging discussions, and networking opportunities. We can't wait to see you at the **April Symfony User Group**!" If you have any questions or accessibility requirements, please reach out to us. Also, if your company wants to be the next host for the User Group, just let us know!

About his keynote: "Data access and reuse are still unsolved, and AI agents are making it worse. This talk goes deeper into that problem: AI agents depend on reliable context (data, features, intermediate state) to make correct decisions. In practice, this context is tied to specific pipelines or infrastructure, leading to brittle systems when moving from prototype to production. I'll show how a plugin-based approach lets teams build deterministic context layers: separating what you compute from how you compute it, so the same feature definitions work on a laptop and in production. The talk includes a live demo where an AI agent discovers and queries data features programmatically. " **Behnaz Derakhshani: *"What If I Started Today?

Recent work on industrial anomaly detection has primarily focused on manufacturing scenarios with highly controlled poses and a limited number of object categories. Existing benchmarks like MVTec-AD (Bergmann et al., 2021) and VisA (Zou et al., 2022) have reached saturation, with state-of-the-art methods achieving up to 99.9% AUROC scores. In contrast to manufacturing, anomaly detection in retail logistics faces new challenges, particularly in the diversity and variability of object pose and appearance. Leading anomaly detection methods fall short when applied to this new setting. To bridge this gap, we introduce a new benchmark that overcomes the current limitations of existing datasets. With over 230,000 images (and more than 29,000 defective instances), it is 40 times larger than MVTec and contains more than 48,000 distinct objects. To validate the difficulty of the problem, we conduct an extensive evaluation of multiple state-of-the-art anomaly detection methods, demonstrating that they do not surpass 56.96% AUROC on our dataset. Further qualitative analysis confirms that existing methods struggle to leverage normal samples under heavy pose and appearance variation. With our large-scale dataset, we set a new benchmark and encourage future research towards solving this challenging problem in retail logistics anomaly detection. The dataset is available for download under [https://www.kaputt-dataset.com](https://www.kaputt-dataset.com). *About the Speaker* [Sebastian Höfer](https://www.linkedin.com/in/sebastian-h%C3%B6fer-891178121/) is an Applied Science Manager at Amazon Fulfillment Technologies & Robotics, leading machine learning and computer vision research for large-scale robotics and warehouse automation. He received his PhD from the Robotics & Biology Lab at TU Berlin, focusing on Sim2Real transfer and robotic perception. His recent work, “Kaputt: A Large-Scale Dataset for Visual Defect Detection” (ICCV 2025) [37], established a major benchmark for industrial anomaly detection, reflecting his expertise at the intersection of academic research and real-world deployment. **Data Foundations for Vision-Language-Action Models** Model architectures get the papers, but data decides whether robots actually work. This talk introduces VLAs from a data-centric perspective: what makes robot datasets fundamentally different from image classification or video understanding, how the field is organizing its data (Open X-Embodiment, LeRobot, RLDS), and what evaluation benchmarks actually measure. We'll examine the unique challenges such as temporal structure, proprioceptive signals, and heterogeneity in embodiment, and discuss why addressing them matters more than the next architectural innovation. *About the Speaker* [Harpreet Sahota](https://www.linkedin.com/in/harpreetsahota204/) is a hacker-in-residence and machine learning engineer with a passion for deep learning and generative AI. He’s got a deep interest in VLMs, Visual Agents, Document AI, and Physical AI. **Most AI Agents Are Broken. Let’s Fix That** AI agents are having a moment, but most of them are little more than fragile prototypes that break under pressure. Together, we’ll explore why so many agentic systems fail in practice, and how to fix that with real engineering principles. In this talk, you’ll learn how to build agents that are modular, observable, and ready for production. If you’re tired of shiny agent demos that don't deliver, this talk is your blueprint for building agents that actually work. *About the Speaker* [Bilge Yücel](https://www.linkedin.com/in/bilge-yucel/) is a Senior Developer Relations Engineer at deepset, helping developers build agentic AI apps with Haystack. Passionate about AI, she makes complex concepts approachable through hands-on tutorials, both online and at real-life events. **Operationalizing Computer Vision for Overhead Lines: Beyond the Demo** At first glance, visual inspection of high-voltage power lines seems straightforward: collect imagery, run one or two AI models, and report the findings. In practice, moving beyond a proof of concept reveals a range of issues that can make or break a campaign. Common concerns include data quality and coverage, scarcity of the most relevant cases and abundance everywhere else, variations in pylon geometry and asset types across regions, calibration and GIS alignment challenges, and a long tail of edge cases that emerge in real-world operations. This talk introduces Siemens Energy’s end-to-end overhead line inspection solution and shares key learnings from inspecting more than 10,000 km of power lines for real customers across several continents. We will show how raw 2D/3D data is transformed into structured information, delivering insights into asset inventory as well as defects, and supporting maintenance and planning decisions for critical infrastructure. The focus is on the combination of algorithmic building blocks and scalable processing, designed for robustness and consistency at scale, where even low error rates can become operationally significant. *About the Speaker* [Stefan Wakolbinger](https://www.linkedin.com/in/stefan-wakolbinger-aa0ba874/) is the Development Team Lead for AI & Analytics at SIEAERO, Siemens Energy's digital powerline inspection service. He leads the development of cutting-edge AI and analytics solutions that transform aerial powerline inspection through multi-sensor technology.

Raw, unstructured, and full of noise. The first step was making them worth keeping: trimming duplicates, removing what no one ever read, and transforming what remained into structured, queryable signals. That foundation changed everything. Once logs became first-class — with clean attributes, consistent structure, and a clear purpose for every line — the rest of the observability stack followed naturally. Monitors built on log queries. Dashboards that actually meant something on incidents. Metrics generated directly from log attributes, giving us long-term retention without the cost of keeping everything raw. **📅 19:45 - Best Practices for Alerting with Datadog (30 min.)** **🎙️**Speaker: Santiago Gomez Saez, Datadog ambassador & Principal Cloud Architect @ **[dxone](https://www.dx.one.gmbh/)** Operational excellence is the main objective of SRE teams.

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
