When you’re living an untethered life, traveling, or just navigating a busy routine, finding a true sense of belonging can take a backseat. That’s why Gals That Brunch exists. We don't believe in stiff networking or forced interactions. We create warm, inclusive, low-pressure spaces where no woman is left sitting on the sidelines. For this gathering, we are heading to Triptolemou 26 in Gazi. Located just a short stroll from the Kerameikos metro and the iconic Technopolis chimneys, this spot captures the artistic, industrial heart of Athens. With its bright urban layout and cozy atmosphere, it is the perfect sanctuary to pause, recharge, and match faces to new, lasting friendships. What to Expect: Great Food & Fuel: Outstanding specialty coffee, fresh juices, and a fantastic brunch menu featuring everything from perfectly poached eggs to sweet, indulgent weekend treats. Instant Inclusivity: If you are nervous about showing up alone, please don't be! Around 90% of our attendees sign up by themselves. Our hosts will greet you at the door, introduce you to the group immediately, and make sure you feel right at home. A Diverse Table: Open to all women in Athens—locals, expats, digital nomads, and global travelers.

Shut Up & Write!® [PIRAEUS / Athens]
Shut Up & Write!® [PIRAEUS / Athens]
Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. SCHEDULE: 11:00 - quick intros. 11:15 - timer starts: write for 1 hour. 12:15 - (the end) chat / take off / keep writing / socialising. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing. BEING LATE IS OKAY: just show up and get settled, then check-in with me after the session. If you were on time, please be willing to make room for the friendly latecomer. Happy writing and I look forward to seeing you at To Theatron! What Should I Bring? Whatever you need to be able to write! Bring earbuds/earplugs if you want to block the cafe’s overhead music or the occasional conversation by other patrons. Ideally come with your laptop fully charged in case there are not enough plugs for everyone. Other Important Details: -Theatron is close to the newly-opened metro station Dimotiko Theatro. The tram also stops right outside, and there are several bus stops nearby. -There is a parking service nearby on Kountouriotou 137 if you are unable to find a parking space. -Please thank our hosts by purchasing something.

Data & Analytics Wednesday - Learning from Everyday Data
Data & Analytics Wednesday - Learning from Everyday Data
**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

Stop Guessing: How to Measure and Improve LLM Outputs
Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
