Building a **SaaS** is a battlefield on its own, now imagine doing it in Greece. On the **7th of April,** **Konstantinos Livieratos** will be sharing the behind-the-scenes story on how **fundamenta** was built, a platform aiming to reshape market intelligence in the Greek market! Expect GDPR challenges, competitors copy-pasting their work into ChatGPT like it's an Olympic sport (they'd probably win 🥇) and several Greek bureaucracy moments enough to test any founder's sanity... It's a story about pushing meaningful change into a market that wasn't fully ready for it, the unexpected hurdles along the way, and why creating a market-local **SaaS** can be far tougher than going global. 📍 You will find us at our host **Starttech Ventures**, downtown Athens: **Lykourgou 1**, 2nd floor ***Starttech Ventures*** *is a venture studio based in Athens, building B2B SaaS companies for global markets since 2000. We co-found companies with entrepreneurs, grounded in a philosophy of trust-based, long-term value creation. Our approach draws on Lean Startup and product-led growth principles to systematically take ventures from first hypothesis to profitable, resilient scaleup. What started as a student-led company in Heraklion, Crete has grown into one of Europe's earliest venture builders, with companies like Epignosis (the team behind TalentLMS), Yodeck, and AbZorba Games proving that it is possible to build globally successful companies from Greece, prioritizing customers over investors and real value over paper value.* #foobario #fundamenta #StarttechVentures #SaaS #meetup #SoftwareEngineering

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.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.

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

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)
