The world needs leaders. Leaders head families, coach teams, run businesses, and mentor others. These leaders must not only accomplish but must also communicate. By regularly giving speeches, gaining feedback, leading teams, and guiding others to achieve their goals in a supportive atmosphere, leaders emerge from the Toastmasters program.

Through our community of learners, they find their path to leadership.

We don’t shy away from the 'M' word at our table. Normalizing conversations about money is how we empower our circle — whether that’s exploring how to make your wealth work for you while you sleep, navigating the hurdles of investing, or sharing the financial challenges unique to women. These topics deserve a safe, casual space. Because real empowerment isn’t just a mindset; it’s about having the tools to fund your freedom. We’re here to bypass surface-level networking and dive into the things the corporate world often ignores. COME JOIN US IF YOU'RE * **Building your Budapest circle**, weather you're a local or a newcomer (expat), ready to make this city feel like home. * **Hungry for high-fidelity connections** that go deeper than a business card. * **Eager to swap stories** with women who see the world differently than you do. * **Looking for your people** and a supportive space where you can be inspired and offer a hand to others. THIS IS HOW IT WORKS **We discover the city’s hidden gems together.** Once you register, you’ll receive the secret location for our gathering. **You’ll be greeted with a warm welcome hug** **and your first coffee (or tea) is on us**. We keep our groups intimate to ensure real conversation. With the help of a facilitator and our custom cards, we open the door to insights you won't find anywhere else. **No pressure, just presence.** You can stay quiet and listen, or share your wisdom with the group. You only share what you’re comfortable with. When the gathering ends, the connection continues, and you’ll be invited to our private community to keep the chemistry going. WHY WE ARE DIFFERENT We know the algorithm loves loud, party-style events, but we believe in the power of the intimate and the intentional. We are here for the women who want to be seen, heard, and truly connected. 👉 Take your seat at our table.[ Register here](https://luma.com/mwb10eo1) \-\-\- *This group is part of the Women's Coffee Network.

This one-day hackathon brings together developers, AI enthusiasts, and innovators to build practical solutions using agentic AI - systems that can autonomously work toward defined goals. Participants will collaborate in teams to design and prototype real-world AI applications and present their projects to a professional technical jury from the industry. The event connects university students with the tech ecosystem through hands-on challenges, mentorship, and technical talks. Participants will work in teams of up to 5 members, so make sure your team includes a mix of skills such as development, data science, AI, product thinking, and presentation. The hackathon is open to both Hungarian and international participants, creating a diverse and collaborative environment. 📅 Date: April 11, 2026 ⏰ Time: 10:00–21:00 CET 📍 Location: Budapest (TBA) 🌐 Language: English 👥 Expected attendance: 100–150 participants Come build, learn, and compete with some of the most active tech communities in Hungary. 🚀 Az eseményről Csatlakozz az első közös GDG Agentic AI Hackathonhoz Magyarországon, amely egyesíti a GDG Budapest, a GDG on Campus ELTE, a GDG on Campus BME és a GDG on Campus UniDeb közösségeit.

A résztvevők csapatokban dolgoznak majd valós AI-alkalmazások tervezésén és prototípusának elkészítésén, majd bemutatják projektjeiket egy szakmai zsűrinek az iparágból.

We are back. And yes, we're keeping the Friday tradition alive! For this event, we’re cutting through the noise. In a world where everyone is shouting for attention, being "good" isn't enough anymore, you have to be **unforgettable**. This time, we’re dissecting the art of becoming truly memorable, both on stage and on the screen. This isn’t about cheap marketing hacks or shallow virality. It’s about understanding the core mechanics of how to make your ideas stick, how to resonate deeply with your audience, and how to scale a brand that commands the room. **The Agenda & What You'll Learn:** Two expert angles, one goal: Make sure you never blend into the background again. **17:45:** Arrive, grab a drink, and connect. **18:10 – 18:15: Event Kickoff & Intro.** Setting the stage for a night of high-impact learning. **18:15 – 18:30: How to be a Memorable Presenter (by Alex MacIntosh).** Ever wonder why some talks echo in your mind for days, while others fade before the speaker even leaves the stage? In this hyper-focused session, Alex breaks down the exact anatomy of "sticky ideas" and how to weaponize them in your presentations. You’ll discover the psychological hooks that guarantee your audience leans in, pays attention, and actually acts on your core message. Walk away with an actionable framework to ensure your next pitch is unforgettable. **18:30 – 18:45: How to Build a Memorable Online Presence (by Chris Parker).** "Build it and they will come" is a lie in today's crowded digital landscape. Chris Parker-entrepreneur, Kajabi expert, and digital growth strategist-will reveal how to cut through the noise and scale a premium digital brand. He'll share his proven approach to identifying the bottlenecks holding your business back and how to deeply tune into your brand to create massive growth. You'll learn how to position your expertise so you can work smarter, not harder, and transform quiet followers into high-paying clients. **18:50 – 20:00:** Genuine networking & conversations with quality food and drinks. **20:00 onwards:** We are heading to a nearby bar. We expect the conversation to go late. **Who Is This For?** This is for freelancers, digital nomads, and founders in Budapest who want to disaster-proof their work and amplify their impact. Join a community of curious, open-minded people for an honest conversation. No corporate fluff, just genuine connections and actionable takeaways on how to stand out. **Location:** We'll be hosting at the fantastic KLUSTER Coworking space. **The Legal Bit:** During the event, we'll be taking some photos. By attending, you consent to this. Thanks for reading, see you on the 10th! Bence & Nándi

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
