Only 1% of Venture Capital reaches all-female teams. Nina Wöss is on a mission to change that. ### Gender-diverse and and all-female startups receive just 9% of all venture capital according to the latest Female Founders Monitor 2025 published by Start-Up Verband Germany and Bertelsmann Stiftung in 2025. These numbers have not changed much in the last 10 years. New ideas are needed to change a system that is not leveraging all its potential. Creating new specialized venture funds is one solution. In this session, Nina Wöss—Managing Partner of the VC Fund F tells us what motivated her to found a venture capital fund specializing in gender-diverse founders only. Fund F writes cheques of up to EUR 600k, acts as lead investor, and brings an active follow-on policy—backed by a team of entrepreneurs, investors, and operators who provide hands-on support and connections to their portfolio companies. Nina will also pull back the curtain on how VCs actually think and what they look for. She previously founded the Female Founders Community with 83.000 members all over Europe and is a leading figure in Austria’s VC Scene. #### 💡 What you will learn * What **VC funds in general and Fund F** in particular **looks for in early-stage startups** and how to get on their radar * Why **gender-diverse teams outperform** all-male teams * **Concrete steps** you can take today to **strengthen your fundraising position** This event is brought to you by **SIBB Incubator**, who supports founders building the future of cybersecurity, trustworthy AI, and deep tech. #### 🧑🏻‍🏫 Speaker **Nina Wöss - *Managing Partner, Fund F*** * **Founder** and **Managing Partner** of **Fund F**, Austria's first VC fund specifically for female and gender-diverse founding teams * **Co-founder** of **Female Founders Global** (since 2016), one of Europe's largest communities for female entrepreneurs * **Former Principal** at **Speedinvest** * **Former COO** at **AVCO** (Austrian Private Equity & Venture Capital Organisation) * MSc in **Strategic Management**, WU Vienna * **Active in the startup ecosystem** since 2012 ***Moderated by: Etta Dannemann in her role as head coach.*** Etta Dannemann moderates the event in her role as Startup Coach at the SIBB Incubator. As a solopreneur, trainer, and architect by education, she loves creating new things — but even more, supporting others as they build and grow. Etta is passionate about empowering women in tech, helping them turn their ideas into action and leave their unique mark on the world. #### 🎯 Who is this event for * **Gender diverse teams** and **female founders** who are preparing a **funding round** * Anyone who wants to **understand** **how VCs think** * **Startup ecosystem** professionals, accelerator participants, and/or incubator members We look forward to seeing you!

This talk walks through a practical demo of automating the full SRE lifecycle: from incident investigation to deployment validation, using Grafana MCP and the GitLab Agent Platform, and where humans still need to stay in the loop. *Serhii Vasylenko* **The Pipeline Was Green — AI Agents and CI Trust** We’ve spent years building CI/CD pipelines that tell us when code is "technically correct," but are they capable of telling an autonomous AI agent if a change is safe to apply? This talk explores a real-world incident where an AI-powered automation -- pairing Renovate with Claude Code -- successfully executed a "green" pipeline that broke a critical QA cluster for three days, how the team reacted, and how we evolved our vision toward the future of human-agentic collaboration with code. *Frithjof Hoffmann* **Managing Uninvited Guests: Securing Open Source Dependencies** Open source software is the ultimate neighborhood party, but what happens when an uninvited guest slips through the door? This talk digs into the messy reality of dependency hell and its role in software supply chain security: from typosquatting attacks to maintainer account takeovers, and the abandoned projects with known CVEs quietly living in your codebase rent-free.

**👋 Hello Strangers! —** For all players and chess-curious folks out there who want to chill, make friends, and enjoy some chess: We are hosting a daily meetup in Mitte / Prenzlauerberg for all experience levels. It doesn't matter if you just watched the Queen's Gambit or if you have been playing regularly for a while. **Join us** — Daily from 7-11pm **Expected Behavior** — [Conduct](https://strangerchess.com/conduct/) **Pics** · [Instagram](https://www.instagram.com/strangerchess/) / **Chat** · [Telegram](https://t.me/strangerchess) / **Web** · [Strangerchess.com](https://strangerchess.com/) (No need to bring anything, boards, clocks, etc. are provided)

In this course, we will build on and review the topics from Casino III–V. To join, you should already be familiar with figures such as: **enchufla variations, desplazamientos (saloneo / paseos), Coca-Cola, vacílala**, and similar material. We will continue adding **footwork and arm styling (functional styling)** to enrich your dancing while keeping your movements clear, connected, and functional. ✨ In addition, we will explore how to enrich your dancing with elements from other Cuban dances. You will learn to use your body more consciously and to interpret the music through movement, rhythm, and personal expression — rather than simply connecting one figure after another. Cuban Salsa (Timba) is deeply connected to other Cuban dance and music traditions, such as **Rumba Guaguancó**. We want to show you how to integrate this richness into your dancing and express the music in a more authentic and musical way. 🎶✨ As always, we stay true to our philosophy: 💛 *It’s not the number of figures that makes you a “good dancer” — it’s your communication with your partner and with the music.* If you need more information or are unsure whether this level is right for you, feel free to contact us 😊 📧 [info@puntocubanoberlin.com](mailto:info@puntocubanoberlin.com) 📞 +49 155 100 966 28 **💛 What to Expect from a Free Trial Class** **If you choose to join a free trial class, please note that you will be joining an ongoing course.** **The purpose of the trial class is twofold: it gives you the opportunity to get an impression of us as teachers, our teaching style, and the level of the course, while also giving us the opportunity to get to know you as a dancer.** **We believe that one of the advantages of joining a dance school is being able to trust the teachers' experience and criteria.** **During the trial class, we not only help you decide whether the course feels right for you, but we also assess whether it is the best fit for your current level and learning journey.** **Our goal is not simply to place you in a class, but to help you find your happy place within our dance community — the environment where you can learn most comfortably, progress steadily, and enjoy dancing the most.** **The final decision regarding the level is therefore ultimately ours. If we notice that you are struggling significantly with the material, we may ask you to observe the remainder of the class and recommend a different level instead.** **This is not meant to embarrass you or make you feel uncomfortable. Quite the opposite: it allows us to stay true to our values regarding technique, learning quality, and the comfort of the students who have been learning and progressing in the course over time.** **In the long run, you'll probably be grateful for being placed in the level that supports your growth and enjoyment the most. 😊** **We are very much looking forward to meeting you and dancing with you!** **Yago, Helen, Pamela, Marion, Leo & Sylvaan**

Participants learn essential music theory concepts, how to choose effective samples & how to design original sounds. The focus is on building a strong sonic and musical foundation for ideas & tracks. **Module 2: Beat & Groove Programming** Development of rhythm, drum patterns, and groove-based elements. This module focuses on timing, swing, layering, and creating dynamic, modern beats that support vocals, songwriting & production ideas. **Module 3: Vision, Songwriting & Recording** This module focuses on artistic direction and expression.

**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.

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

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.

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.
