**PyBerlin: March event** **Sponsor**: Spiced Academy **Location:** Spiced Academy, Ritterstrasse 12-14, 10969 Berlin, Germany **Agenda:** 6:30 pm – Doors open: snacks, drinks, networking 6:55 pm - Welcome from PyBerlin 7:00 pm - Welcome from the sponsor - Spiced Academy **7:10 pm** – **What Actually Changes Customer Behavior? Causal Thinking Across Attribution, Segmentation, and Growth // Dr. Maryam Ramezani-Bartsch** Customer data is often used to explain what happened: attribution assigns credit, segmentation groups users, and dashboards track performance. Yet marketers and business leaders still struggle with a more fundamental question: what actually changed because of our actions? This talk introduces causal thinking as a practical way to interpret customer data across attribution, segmentation, and growth. It shows why correlation-based metrics can be misleading and how counterfactuals and incrementality help teams ask better questions when they look at results. A concrete email campaign example illustrates how causal uplift modeling separates customers who would have purchased anyway from those whose behavior truly changed. The goal is to help data scientists, marketers, and decision-makers move from reading metrics to reasoning about incremental impact and to make better decisions because of it. Speaker's bio: Dr. Maryam Ramezani-bartsch is a data and analytic leader with over 20 years of global experience building and scaling customer analytics and data science teams. She has led the development of customer data, marketing measurement and targeting capabilities for global brands such as adidas, Sky, Delivery Hero, and Zalando, helping embed customer-centric, data-driven decision making across organizations. Her work focuses on building customer data models, causal analytics, experimentation, and developing teams that turn insights into sustained business impact. **7:40 pm - Python 3.14 & 3.15 news! // Hugo van Kemenade** The release manager will share some of the exciting things in the newest versions of your favourite programming languages. **7:50 pm - break** **8:10 pm** – **Your Next On-Call Engineer could run Locally //** **Anthony Alaribe** What if your next on-call engineer wasn't a person, but a Python agent running on your machine? Inspired by the explosion of local agents like OpenClaw, this talk explores what happens when we point agentic workflows at the systems we monitor. We'll walk through the checklist most engineers actually run during on-call: checking dashboards, tailing logs, correlating errors with recent deploys, and then explore how to build a custom Python agent that automates these checks using tools like LangGraph, OpenTelemetry, and the Anthropic SDK. You'll leave with a working starting point and a new way to think about what agentic AI can do beyond chatbots. Speaker's bio: Anthony has spent over a decade building software at companies like Opera, and DeliveryHero. He has faced his fair share of dealing with unreliability software and breaking changes in APIs, including losing over $2m in orders to such an incident, amongst other war stories. Say hi when you him. He loves conversations about AI, databases, and programming languages. **8:40 pm – What makes XGBoost so powerful // Rakibur Rahman** XGBoost (Extreme Gradient Boosting) is one of the most influential machine learning algorithms of the last decade, originally developed by Tianqi Chen. It has become the default choice for structured (tabular) data problems, widely used in both industry and data science competitions on platforms like Kaggle. This talk explains why XGBoost works so well, from both a mathematical and practical engineering perspective. Speakers bio: Rakibur Rahman, PhD is Senior Coach of Data Science & AI at Neuefische/Spiced Academy, Berlin, with 20+ years of analytical problem solving and data analysis experience. With a background in Theoretical Physics, he is keen to apply cutting-edge machine learning algorithms and AI tools for driving positive business impact. Endowed with the ability to present complex ideas in simple pedagogical form, he delivered 50+ professional talks at the international level. His global experience includes working/studying in the USA, Germany, Italy, Belgium and Bangladesh. 9:10 pm - closing This event will be only in-person.

We will have plenty of events in different formats in the future. Looking forward seeing you all!

Mit dem Titel "Philosophie 2.0" wird nicht zu viel versprochen. Nicht alles was mit 'Philosophie' bezeichnet wird, hat damit auch zu tun. Das gilt allgemein. Wörter werden zu oft nicht präzise gebraucht, aber wenn man alles mit beliebigen Wörtern bezeichnen würde, könnte man nichts mehr genau verstehen, könnte nichts mehr genau begreifen. Also blieben die Irrtümer bestehen. Das hätte mit Philosophie aber definitiv nichts mehr zu tun. Was also ist das Gegenteil belanglos-vieldeutigen Wörterverdehens mit hochassoziativen Sprüngen bei denen allerlei übersehen wird und ergo das Wesentliche nicht mehr als solches klar erkannt werden kann? Maximal exakte Begriffsklärung. Und das geht! Das geht über einen systematischen Aufbau aller Kategorien - gestützt über einen Algorithmus, welcher Kategorienfehler automatisch vermeidet und mithilft, das Ganze im Blick zu behalten. Dass dies für uns Personen gar nicht so einfach ist, sieht man daran, dass jede Person (auch Du) irgendwann irgendwelchen Irrtümern aufgesessen ist. Jede Person, die sich also für irgendetwas ernsthaft (nicht wegen blanglosem Amüsement, oder wegen ideologischer Rechthaberei) interessiert und ergo dafür offen ist seine Auffassungen weiterzuentwickeln, ist bei dieser Veranstaltung goldrichtig. Ablauf: Bei unserer Diskussion geht es dabei nicht um irgendein festes Thema, sondern jeder schreibt ein Wort in seinem Interessengebiet auf einen Zettel und wir ziehen diese paarweise für je eine Runde. Die beiden Wörter haben gemeinsame Kategorien, aber es gibt auch Unterschiede. Wer diese nicht alle kennt, kann nicht behaupten, dass er tatsächlich begriffen hat, wovon er meint, dass es ihn interessiere; dass er definitiv wüsste wovon er spricht. Dieses Problem hatte schon Sokrates erkannt. Nur haben wir jetzt einen Algorithmus, welcher zu absoluter Genauigkeit verhilft um diese Irrtümer loszuwerden. Daher 'Philosophie 2.0'. Siehe dem Bild oben werfen wir die Bedeutung (die Menge aller Kategorien einer Begrifflichkeit) per Beamer an die Wand. Wir sind nicht in der Schule, d.h. es gibt keinen Zeitdruck, keine Noten, keinen Wettbewerb und keine Profilierungsmotive, sondern jeder hat alle Zeit der Welt um über die schematisch dargestellte Bedeutung nachzudenken - und diese zu hinterfragen. Die grafisch dargestellten Bedeutungen des Algorithmus sind nicht perfekt. Es geht nicht darum irgendetwas zu akzeptieren, sondern andersherum: die Bedeutung anzugreifen und zu verbessern. Jeder kann sie ändern! Die Diskussion ist also eröffnet. Jeder muss Gründe angeben. "Kann ein Walfisch ein Wellensittich sein?" \~> Natürlich nicht, denn Säugetiere sind keine Vögel. "Kann ein Fenster ein Getränk sein?" \~> Jeder weis, das ist unmöglich, denn Festkörper sind keine Flüssigkeiten. "Kann eine Demokratie eine Republik sein?" "Kann eine Vermutung eine Meinung sein?" "Ist etwas zu begreifen das Selbe wie etwas zu verstehen?" Nichts regt dermaßen zum nachdenken an wie die Bedeutung der Begrifflichkeiten algorithmisch stabilisiert zu systematisieren. Und wenn wir uns nicht einig werden? Die Diskussion läuft auch nach der Veranstaltung weiter. Jeder kann online von zuhause die Diskussion fortführen - mit dem selben mitdenkenden Algorithmus. Man könnte sagen, es sei ein neues Gesellschaftsspiel - ohne Wettkampf, sondern in kollektiver Bereicherung an Klarheit, von der alle gigantisch profitieren, obschon jeder nur einen sehr kleinen Teil beiträgt. Das "Spiel" funktioniert auch mehrsprachig, denn der platonische Raum der Begrifflichkeiten ist der eindeutige Raum, auf den das Vokabular einer Sprache nur referiert. Man kann auch von Zuhause aus online mitmachen. Den Zugang können wir dann über die Kommentare hier organisieren. Bring deinen Laptop mit, dann wird es einfacher... Dieses Spiel macht klug: Schach trainiert zwar das Konzentrationsvermögen, hat aber mit der Wirklichkeit nichts zu tun. Dieses Spiel hingegen schon, denn genau mitdenken zu können setzt voraus genau zu unterscheiden. Wer die Bedeutung der Wörter sauber ausdifferenziert wird immer klüger. Mach mit!

Ihr lernt Euch kennen und habt Spaß. 4. Wer mag, trifft sich wieder. . Du wirst überrascht sein, wie vertraut Du mit vielen nach 3 Stunden sein wirst - so, als ob Ihr Euch schon lange kennt. . **🔱 4 Jahre Arbeit - 1 Workshop** Vier Jahre habe ich geforscht und ausprobiert, wie Menschen Freunde werden & was die Magie der Freundschaft ausmacht. Das Ergebnis ist dieser Abend. . Praxisnahe, schnell umsetzbare Tipps, die Du schnell in den Alltag umsetzen kannst. Kleine Happen zur Theorie. - Und vor allem: Kennenlernen & Spaß haben. Wir probieren einfach miteinander aus. . Eine Teilnehmerin sagte mal zu mir: * "Georg, das ist so eine angenehme Atmosphäre. Danke, dass Du das machst." . Was soll ich sagen? Stimmt. Das ist mein Anliegen 🤗. . . **🎁 Diese Methoden kannst Du in Deinen Alltag mitnehmen.** Ab sofort kannst Du Menschen besser und persönlicher kennenlernen – und damit tiefe Verbindungen und bessere Freundschaften aufbauen. . . **⏰ Die Türen sind offen ab 18:45 Uhr.** * Deinen Mantel aufhängen, WC, eine Runde schwatzen und los geht's... . **❓ Darf ich wiederkommen?** Es gibt nur wenige Veranstaltungen, bei denen man wirklich miteinander ins Gespräch kommt.

Da sind wir. 🤗 . **👱🏽‍♂️ Warum moderierst Du als Mann diesen Workshop?** . Hi, ich bin Georg. Ich weiß, ich bin ein Mann. Warum moderiere ich dann diesen Workshop? . Abenteuer Freundschaft ist mein Beruf. Am Anfang war ich auf Männer-Freundschaften spezialisiert. Überraschenderweise waren 60 Prozent der Newsletter-Empfängerinnen Frauen. Frauen scheinen die Wichtigkeit guter Freundschaften viel mehr zu spüren. . Deshalb habe ich letztes Jahr angefangen, Workshops für Frauen anzubieten. Soziale Träger, das Rathaus Schöneberg und das Frauenzentrum Begine haben mich bereits für Freundinnen-Workshops gebucht. Im Frauenzentrum moderiert eine Bekannte die Workshops.... denn da darf ich noch nicht mal rein :). . Unseren Workshop werde ich zurückhaltend moderieren. Ich weiß mit der Situation umzugehen. Das ist Euer Raum. . Für die Männer gibt es alle zwei Wochen am Dienstag einen Männer-Workshop, der regelmäßig gut besucht ist. . . **Mehr über Abenteuer Freundschaft & mich:** 🌎 [www.abenteuer-freundschaft.de](http://%5Bhttps://www.abenteuer-freundschaft.de/%5D(https://www.abenteuer-freundschaft.de/) "\[https://www.abenteuer-freundschaft.de\](https://www.abenteuer-freundschaft.de)") . . **👋🏽 Get in touch & stay in touch:** . **✈ Telegram-Kanal: [t.me/abenteuer_freundschaft](http://t.me/abenteuer_freundschaft)** für Events, Workshops & Neuste Erkenntnisse aus der Freundschaftsforschung (Überschriften) . **✉ Freundschafts-Newsletter:** [https://abenteuer-freundschaft.de/newsletter](https://abenteuer-freundschaft.de/newsletter) Alle 4 Wochen das Neuste aus der Freundschaftsforschung; oft seltener, denn ich schreibe nur dann, wenn es wirklich etwas zu berichten gibt. . **🔥 6 Zutaten großartiger Freundschaften** Seit 2020 forsche ich, was großartige Freundschaften wirklich ausmacht.

**🚨🚨🚨 ATTENTION: we moved to luma. please RVSP [HERE](https://luma.com/12min.me_Berlin)🚨🚨🚨** # ​[12min.me](https://12min.me/) START UP is a brand new morning format for bold ideas and fresh perspectives ​Berlin Startup Community, we’re launching something new. Together with betahaus, we’re bringing the [12min.me](http://12min.me/) spirit into the morning. ​[12min.me](http://12min.me/) STARTUP is a three-part breakfast series, embedded in the well-known betabreakfast format. Instead of three speakers in one evening, we do things differently. ​One morning. One speaker. One focused impulse. ​12 minutes. One voice. Zero fluff. ​Join us for the first edition of [12min.me](http://12min.me/) STARTUP, a compact morning session for founders, operators, creatives and everyone building things that matter. ​**✔️ What to expect** * ​One inspiring startup-related talk * ​12 minutes of sharp insight * ​Curated exchange over breakfast * ​The familiar [12min.me](http://12min.me/) energy, just earlier in the day# ​🚀 **The formula stays the same** * ​12 minutes talk * ​12 minutes of Q&A * ​12 minutes of networking ​The familiar [12min.me](http://12min.me/) energy, just earlier in the day ​**🎤 Our speakers** **Speaker 1 @March 5** **[Jonathan Hegel](https://www.linkedin.com/in/jonathan-beisiegel) from [FW Systems](https://www.linkedin.com/company/frachtwerk/)** Jonathan is the CEO of FW Systems, a specialized system house for open source solutions and IT services with a fixed-price model. After years in traditional IT, where he regularly had to work night shifts due to emergencies, he decided to do things better—for customers and for IT professionals. Today, he help SMEs transform their IT from a constant work in progress to a reliable infrastructure they can depend on. **Jonathan\`s talk: "How we are completely rethinking system administration as a service for your company"** Companies cannot possibly do everything themselves. So things like accounting, logistics, and IT are outsourced to external service providers. In the IT sector, system houses have been doing very well for themselves in recent decades! Every little thing is charged for, and if there are any errors, the customer is expected to open a ticket. We are rethinking this! We are applying the “as-a-service” concept from Airbnb, Uber, and Everstox to system administration and taking responsibility. Jonathan will show how this works in his talk. ​ **Speaker 2 @March 12** **[Anne Biedermann](https://www.linkedin.com/in/anne-biedermann/), independent wealth partner for women** Anne has extensive experience across venture capital, single-family-office & HNWI investing, and early-stage operations. She works with investors who are building, inheriting, or stewarding wealth on how to allocate capital with clarity — particularly where venture capital intersects with long-term wealth strategy. Anne also invests personally, giving her a practitioner’s perspective on capital allocation decisions. **Anna\`s talk: "Not All Capital Is the Same: Decoding Investor Behavior"** Founders often assume all investors evaluate risk, timelines, and returns the same way and that assumption is costly. This session breaks down how funds, family offices, and individual investors actually make decisions, where founder–investor misalignment typically begins, and how founders can better position themselves for the right kind of capital, not just any capital. **Speaker 3 @March 19** **[Immo Ait Stapelfeld](https://www.linkedin.com/in/immoaitstapelfeld/), Co-Founder & CEO at [913.ai](https://913.ai)** **"From Legal Complexity to Practical AI. How We Help Regulated Industries Use AI Without Losing Control"** This presentation tells the story of Immo’s transition from a trained lawyer working in mass proceedings to an entrepreneur building AI products for regulated industries.

Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease. This walk is a simple reset. We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment. No apps. No performance. Just a clear space to slow down and notice what is happening. If you want to slow down without withdrawing from life, join a Chitta Walk. ✨ **What to expect (approx. 90 minutes):** * A short arrival and orientation * A guided silent walk (phones off, no conversation) * One concise science-based impulse on attention or stress * Optional reflection in pairs or small groups * A simple takeaway or experiment for daily life 🚶**Who this is for:** * Professionals, creatives, and people in transition. * People who feel mentally busy and want more clarity and balance. * Those curious about mindfulness, but grounded and practical. * Anyone comfortable with silence and gentle self observation. 🔔 **Practical notes:** * Duration: 60-90 minutes * Wear comfortable shoes and weather-appropriate clothing * No prior experience needed * Group size is limited to keep the space quiet and focused 🧭 **Facilitator:** My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction. 🤔 **Why Chitta Walks?** Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense. Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world. The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. 🌿 **Possible effects:** A calmer nervous system. Clearer attention. A felt sense of being more present in your body. Subtle insights into how your mind reacts under everyday conditions. A quieter, more grounded way of moving through the city. **Come as you are. Walk. Notice. Leave with a little more space inside.**

A small NEXUS gathering built around movement rather than discussion alone. This is for high-bandwidth Mavericks who spend most of their time in conceptual thought and need some physical counterweight. Why bouldering? Because it’s deliberate: short problems, full focus, and immediate feedback. You’re on the wall, solving something tangible. The mental noise drops instantly! Conversations happen naturally in between climbs. No pressure, you move at your own pace. Some exchanges stay light. Others go deep. Both are fine. This is not about athletic achievement. It’s about presence, recalibration, and being around people who don’t require you to shrink or translate yourself. Come as you are. Try some bouldering problems. Rest when needed, and engage where it makes sense. **Bring comfortable clothes and climbing shoes if you have them (rentals are available at the gym).** *Registration equals commitment. If you sign up, you show up. Read the group description first and decide consciously.
