**We are back. And by popular demand: We are finally doing this on a Friday!** For Event #4, we’re flipping the script. Forget the best practices. This time, we're focusing on **worst practices.** We’ll dissect real business failures through three lenses: legal, psychological, and marketing. Decisions that looked smart on paper, passed approval, and still detonated. We’ll revisit familiar disasters like **Theranos** and **Fyre Festival**, then go deeper into lesser-known, more uncomfortable cases and even scandals including global brand implosions and local examples like **Shrooly**. **This isn’t about laughing at failure.** It’s about understanding how smart teams convince themselves bad ideas are good ones, and learning how to spot the moment everything starts going wrong. **The Agenda & What You'll Learn** Three angles, one goal: Make sure you don't end up on this list next year. * **17:45:** Arrive, grab a drink (it's Friday!), and connect. * **18:00 – 18:15: How NOT to run your business (legal angle).** We look at the structural red flags that sink ships. From the valuation hallucinations of **WeWork** to the **Honey scam** and local hardware flops like **Shrooly**. We’ll cover how to mismanage cash, ignore the law, and implode your company from the inside out. * **18:15 – 18:30: How NOT to gain customers (marketing angle).** “There’s no such thing as bad publicity” is how this always starts. Then the backlash hits. We’ll break down campaigns that went viral for all the wrong reasons - from **Pepsi and Bumble** to **Bud Light and Apple** \- unpacking how rebrands\, stunts\, and culture\-driven ads cross the line from attention to alienation\, and how brands lose their audience because of some 'viral' ideas\. * **18:30 – 18:35:** **🎁** A super secret surprise * **18:35 – 18:50: How NOT to handle customers (psychological angle).** Users don’t leave when something breaks, instead they leave when something feels off. We’ll explore dark UX patterns, manipulative design, and behavioral shortcuts that quietly cross ethical lines from **friend.com** to platforms that optimized engagement until users turned hostile. This is how loyal users become your loudest critics. * **18:50 – 19:00:** A very special announcement * **19:00 – 20:00:** Genuine networking & conversations with quality food and drinks. * **20:00 onwards:** We are heading to a nearby bar. Since **nobody** has work tomorrow, 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. Join a community of curious, open-minded people for an honest conversation. No corporate fluff, just genuine connections. If you want actionable takeaways on what *not* to do, this is for you. **Location** We'll be hosting at the fantastic **KLUSTER Coworking** space. **The Legal Bit** Our imaginary lawyers (who are currently panicking about this event topic) wanted us to mention that we'll be taking some photos. By attending, you consent to this. Thanks for reading, see you on **the 20th**! Bence & Marguerite & Nándi

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
