Most brands track whether they appear in ChatGPT, Gemini, and AI Overviews. But mentions and citations only tell half the story. In this session, Raoul Schreck, our CEO at Buzzmatic will show you how to systematically analyze what AI actually says about your brand: which attributes it assigns to you, which USPs it credits to your competitors, and where your communicative blind spots are. Using a real client case and a concrete 4-layer framework, you’ll learn how to move beyond visibility tracking and uncover the narratives AI systems are building around your brand — and what to do about them the next morning. Book your ticket now to secure your spot at the Rise & Rank SEO and AI breakfast!

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.

**You are doing the work. But are the right people seeing the value of it?** **In a difficult economy, being good at what you do is not enough. People are making decisions all the time: who gets trusted, promoted, referred, hired, renewed, funded, or invited into the next room.** **If your value is not clear in those moments, the cost is real.** **You get passed over. Your ideas get credited to someone else. Clients question your rate. Managers miss your contribution. You leave important conversations with vague promises instead of a clear next step.** **This workshop helps you make your value visible without sounding defensive, arrogant, or aggressive.** **Small group of max 20. You need working English to participate.** **This is for you if** * You deliver results but the recognition goes to someone else * You are doing more than people realise, but struggle to say it clearly * You over-explain, soften, or freeze in important conversations * You want to be taken seriously by managers, clients, partners, stakeholders, or decision-makers * You are preparing for a review, pitch, interview, promotion, raise, rate, or business conversation **What you leave with** * A framework to make your value clear * Your own real situation prepared and ready to use * Scripts for stating your contribution * Responses for pushback, dismissal, or vague answers * Practice saying it out loud in a small group * A follow-up email with the scripts and tools from the session **About the host:** Sumita Kar is the founder of Take a Brava Leap (TABL), based in Berlin. She spent 13 years building her career across global teams, moving from associate level to Vice President across customer success, cross-cultural leadership, C-level client management, high-stakes escalations, negotiations, and commercial execution.

She has navigated these rooms as an international woman where she was often the only one. She built this session so you don't have to figure it out the way she did.

Join us for the **Berlin DevOps Summer Meetup**: our last edition before the summer break! We're excited to be hosted by **Parloa** for an evening of interesting talks, discussions, and networking. There will be food and drinks provided, and plenty of time to connect with fellow DevOps enthusiasts. **📌 Please register at least 24 hours before the event.** We need to share the attendee list with the Parloa office in advance, and **spots are limited**. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Agenda** 18:30 Open Doors, Networking with Food and Drinks 19:00 Welcome words by Parloa and BLN DevOps team 19:25 **Running K8s with AI: Automating** **the SRE Lifecycle with Grafana MCP and GitLab** 19:50 **The Pipeline Was Green — AI Agents and CI Trust** 20:15 Short Break 20:30 **Managing Uninvited Guests: Securing Open Source Dependencies** 20:55 Networking 21:30 Closing ➡️ Interested in hosting an event?

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.

Monthly working lunch for Columbus business owners. One specific topic, one to three actions you can run this week. You can be the best at what you do and still be invisible. If local buyers cannot find you, the phone does not ring. Marketing Monday Lunch + Learn is a monthly working lunch for Columbus business owners focused on building relationships, local networking, and local marketing. Every kind of local business welcome. No pitch round, no pressure, no upsell. **This month** Most local businesses pick one or two places to be visible and call it good. The result is inconsistent calls and a feeling that marketing is not working. We will walk through the three places every local business needs to show up, plus the fourth place most owners ignore that quietly produces the warmest leads. **What to expect** Doors open at noon. Order lunch and drinks at the cafe counter or bring your own. You get real conversation with other local owners and a focused marketing lesson. You leave knowing people and with one to three actions to run that week. The room is reserved through 1:30 PM. **Who this is for** Any local business owner who wants clearer marketing direction and real local relationships. Service businesses, retail, home services, professional services, online owners building local presence, anyone serious about being part of the Columbus business community. **Not the right fit if** You are here to pitch the room or recruit for an MLM. **Details** * Second Monday of every month * 12:00 to 1:30 PM * Good Cafe Easton, 4400 Easton Commons, Ste 150, Columbus, OH 43219 * Order lunch and drinks at the counter when you arrive * Free to attend, RSVP required, space is limited **About the host** Rita Suzanne is a local marketing strategist and the founder of Local Marketing Method. She runs Visibility is Profitability, the membership where local business owners build the system that keeps their phone ringing. Learn more at learnlocalmarketing.com.

**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 have referrals for you! All visitors are welcome. Any questions contact [pmarchio@farmersagent.com](mailto:pmarchio@farmersagent.com)

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.

Thanks to the team at Nationwide of supporting the group.

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.
