Agenda
| 2. October 2025 | ||
| 8:00 – 9:00 | Registration and Breakfast | |
| 9:00 – 9:05 | Opening Moderator: Martin Szugat |
|
| 9:05 – 9:45 | Opening Keynote Rethinking AI: Are We Climbing the Right Hill? OpenAI took an amazing idea – Transformers – and sold it like a dream: ask AI. Now every company has AI-something to sell, and every country is gearing up for the AI race, turning international research into a form of treason. But what if this madness could be our best chance to put aside the over-excitement about connectionism – without throwing away its amazing results – and think about the next class of problems worth solving? It’s time to rethink AI deeply – while we have the money – and start looking for damn good answers, not just good enough. Speaker: Allessandro Confetti |
|

| 10:45 – 11:15 | Accelerating Marketing Delivery: Axel Springer’s Journey to a Unified Next-Gen Automation Platform Nils, Senior Data Engineer, and Justin, Senior Data Scientist, guide you through this Case Study featuring Axel Springer, known for media ventures like the Polish Onet. They illustrate how initially isolated predictive use cases evolved into a next-gen marketing automation platform that accelerates campaign delivery and drives subscriber growth. Justin explains the analytics behind the first ML use cases for better customer targeting, while Nils details critical data integrations that transformed these insights into a unified Customer Data Chip and seamless automation architecture. This session demonstrates the power of data products and serves as a blueprint for marketing enablement. Speakers: Nils Paetsch & Justin Neumann |
From Chatbot POC to Full-Scale Enterprise AI Solution Creating a basic chatbot has become quite easy in today’s world. With just a few lines of code—often supported by Large Language Models (LLMs)—you can have a generic AI chatbot running on your local machine in just a few hours. But what does it really take to turn a proof of concept (PoC) chatbot into a fully functional solution? How do we transform a simple Python script into a robust application that serves hundreds of users with specific knowledge? How do we ensure our solution works properly every time, and how do we evaluate the outputs? In this session, we will guide you through the development journey of a highly specialized chatbot project that today is in use by more than 1,000 experts within the organization. You will see how we can turn a small initiative into a comprehensive solution. We will look at this process from various angles, including data science and AI engineering, data engineering, DevOps considerations, and the business perspective. Join us as we explore the steps involved in scaling AI solution from concept to deployment. Experience a project that „was” and „is” – a real-life success story with its challenges and considerations – not a theoretical idea that only „may happen.” Speaker: Aleksandra Krystecka & Bartłomiej Kużdżał |
| 11:15 – 11:45 | From Hypotheses to Conversions: Journey to First ML Models at Snaptrip Explore Snaptrip’s path to their first ML Models. How we combined techniques like siamese networks, NLP and ensemble of multiple models in order to achieve conversion improvement on their website. We will describe how we tackled data drift in resource limited environment. You will walk away with description and real tips of practical ways to manage many experiments, and achieving balance between simple and complex approaches. Speaker: Marcin Szymaniuk |
|
| 11:45 – 11:50 | Short Break | |
| 11:50 – 12:15 | From Eye-Catching to Effective: Personalization That Actually Works in the Mol MOVE Loyalty Program at MOL Group What happens when a data team faces a choice between cutting-edge and commercially effective? Working within Mol MOVE, a fuel retailer loyalty program covering 10 CEE countries, we tested both and share our key learnings from those two projects in this session: 1) a hyperpersonalization project, where we conducted microsegmentation, used GenAI to create data-driven personas, and use them to write personalized message to these microsegments 2) a discount optimization project, where we used a traditional AI approach to determine what would be the optimal discount level for every customer in that specific segment. Speaker: Peter Szabolcs |
On Building Better Retrieval Retrieval Augmented Generation is only as good as your retrieval pipeline. While semantic search provides a solid foundation for natural language interactions, many applications hit quality walls that require more sophisticated approaches. This talk covers four key strategies: combining lexical and semantic search through hybrid approaches, integrating business logic via score boosting, leveraging multivector representations for fine-grained matching, and implementing performance optimizations that scale. We’ll explore when each technique shines and how to build retrieval systems that actually serve your users’ needs. Speaker: Kacper Łukawski |
| 12:15 – 12:40 | Causal AI at Scale: Personalization of Push Notifications for Millions of PAYBACK Users In high-scale mobile engagement, sending too many push notifications can alienate users, while too few can limit ROI. We built a causal AI system leveraging GCP to predict the optimal notification frequency for each user based on their behavior and characteristics. By estimating heterogeneous treatment effects through causal forests and validating through A/B testing, we developed a personalized frequency model that maximizes user interest and minimizes fatigue. This talk shares our journey from business constraint to scalable AI-driven solution that now serves millions of users daily Speakers: Dr.Alexander Khachikyan & Arkadiusz Slowik |

| 16:00 – 16:30 | From Reactive to Autonomous: Building Agentic AI at Feedly Most AI products today are sophisticated tools; powerful, but passive. At Feedly, we’re transforming threat intelligence from a reactive discipline to a proactive partnership with AI. This talk traces our journey from RSS feeds to agentic AI workflows, sharing real lessons from building and deploying AI features used by thousands of security teams. I’ll demonstrate how we evolved from keyword matching to semantic AI Feeds, then added generative AI capabilities that analyze, summarize, and create intelligence reports. More importantly, I’ll share our vision for the next frontier: agentic AI that acts as a trusted security colleague; continuously hunting threats, understanding organizational context, and taking autonomous actions. Speaker: Farah Ayadi |
Advanced Prompt Engineering and Beyond: Ingredients Needed for Working LLM Based Products We start with examples of advanced prompt engineering. Then we will show limitations of various approaches and iterate through retrieval techniques and verification. We’ll dive into Hyde and Colbertv2 for ReRank and better retrieval, and Chain of Thought for reasoning. Learn how LLMs can act as judges, balancing fairness and precision. We will also explore when it makes sense to use PEFT. We’ll tackle challenges like sneaky user behavior and testing non-deterministic outputs. Speaker: Marcin Szymaniuk |
| 16:30 – 17:00 | Improving Global Container Repositioning with AIML Forecasting – 10 Years of Insights at Hapag-LLoyd Description: The repositioning of empty containers is a critical challenge for global ocean container carriers. Despite port disruptions, Suez canal closures, adverse weather containers need to be readily available for Christmas shipments of consumer products in China, cherry harvest in Chile, or Salmon season in Norway. Central to the optimization is the accurate forecasting of container demands and their surplus. This session will dive into the logistical complexities of empty container repositioning at Hapag.-Lloyd, one of the worlds largest container sipping companies, and highlight the transformative impact of AI forecasting models by software partner iqast in providing precise demand forecasts on a global scale.
