pan.talk – Wie die KI jassen lernt
**Und was Unternehmen daraus über Sichtbarkeit, Kontrolle und Vertrauen in der KI-Welt lernen.**
«Stöck, Wyys, Stich.» In der Schweiz weiss jeder sofort, was gespielt wird. Die grossen KI-Modelle kennen unser Kulturgut jedoch nur oberflächlich. Wo das Trainingsmaterial dünn ist, erfinden sie die Regeln mit voller Überzeugung.
Dasselbe Problem hat fast jede Firma mit ihrem internen Fach- und Produktwissen. Remo Prinz zeigt, wie man durch strukturierte Daten Teil des KI-Training Korpus wird, verlässlich zitiert wird und dieses Fundament über ein autorisiertes Model Context Protocol (MCP) zu einer kontrollierten, vertrauenswürdigen Live-Quelle ausbaut. Ist es ausserdem möglich, ein Modell zu trainieren, das nicht nur perfekt jasst, sondern als geduldiger Mentor jeden Zug erklären kann?
Ein Abend über Tradition, strukturierte Daten – und die Frage, wie Organisationen in der KI-Welt zur Quelle werden, der die Maschinen vertrauen.
Trust, but Sandbox
**Trust, but Sandbox**
Agents are becoming more autonomous, are expected to work more independently, and are being granted greater privileges. They install tools as and when they need them. And they can access all files on the system, use the browser with existing cookies, and much more. How can we allow the agent to work while still maintaining control?
The talk will present three methods for isolating coding agents and compare their advantages and disadvantages. First, I’ll outline the capabilities of a local agent and the risks that come with them. In a live demo, I’ll show just how simple sandboxing can be and how great it feels to switch to ‘YOLO mode’ without a second thought and let the agent work on his tasks. Finally, we’ll take a look at some practical features that a separate environment for agents can offer.
**Michael Krämer** is working in software development for over 20 year and works as a Software Architect at INNOQ. He is very commited to work out component designs with clearly defined responsibilities and to find appropriate solutions for requirements. Besides that he is engaged in Machine Learning, the integration of ML models in production environments and works as a trainer for Software Architecture.
KIDS Summer Art Camp
This special holiday program is perfect for children who love being creative and want to try out different techniques. Inspired by the "All You Can Eat" principle, you can create as much as you like within your booked time.
What can you create?
During the summer holidays, you'll have a wide range of creative activities to choose from. You can focus on one technique or try several.
Manga Drawing (1.5 hrs) \*starts at 1:00 pm\*
Learn step-by-step how to draw manga characters. You'll learn the basics of manga faces, eyes, and proportions, and you can create your own character.
Pottery (2 hrs)
Shape a small bowl, mini vase, or figurine with your hands! I'll show you how!
Acrylic Painting (2 hrs)
Paint your own picture with acrylic paints on canvas. Whether it's cute animals, food illustrations, or summer scenes – let your imagination run wild!
Coloring (0.5 hrs)
Perfect for relaxing between other projects. Choose a template or create your own design and experiment with colors.
Decoding (0.5 - 1 hr)
In this popular technique, you decorate objects with a creamy paste and cute decorative elements. For example, cases, mirrors, or small boxes. The finished piece needs to dry overnight in the studio and can be picked up the next day. (max 3)
Punch Needle (1 - 2 hr)
Using yarn and a special needle, you create textured patterns and small textile artworks. This technique is easy to learn and especially fun.
Crochet Tote Bag (1 hr)
Using simple crochet techniques, you can make a small bag or accessory from yarn.
Design Jewelry & Keychains (0.5 - 1 hr)
Create your own bracelets, pendants, or small gifts.
Hand Lettering & Greeting Card Design (1 - 1.5 hr)
Learn beautiful lettering and design personalized cards – perfect for birthdays or short messages.
Nail Design (1 hr)
You can also get creative with your nails. For hygiene reasons, please bring your own nail file and nail polish.
Just like with "All You Can Eat," there's only one important rule at All You Can Create:
👉 You must complete your project.
If a project appears incomplete, an additional fee of 10 CHF will be charged. This rule helps ensure that the creative space is used fairly for everyone and motivates participants to consciously complete their projects.

Design by Instinct. Then Prove It with Data.
**If your design feels right, how do you prove that it works?**
Creatives are taught to trust their instincts, and rightly so. But intuition alone can leave your best work undefended in the room, and it cannot tell you whether a design actually changed anything. What looks better in a critique still needs to prove that it creates value in the real world.
So, the real challenge is knowing what works, not just what looks good.
In this keynote, **Mario Stipetic**, product designer, engineer, and product manager based in Zürich, introduces data-driven design as a practical way to use evidence without killing creativity.
With over 14 years of experience designing and building SaaS web and mobile products end to end, including as Head of Product Design at a US-based fintech, Mario works at the intersection of design, product, and engineering.
Join us on **June 30** as Mario shows, through real before-and-after case studies, how simple data can help teams test ideas, iterate faster, and build products people keep coming back to.
**💡 What will you learn?**
* Why creativity and data work best together, and how measurement helps you defend your design decisions
* How simple methods like a 1–5 survey, a funnel, or a fake button can give you real proof without a big team or budget
* How to set a clear hypothesis and one metric before you design, then measure before vs after
* How to read what the data is telling you and turn it into sharper copy, visuals, flows, and product decisions

AI and the Teams That Make It Work
Two complementary takes on what actually decides whether AI delivers value in an organization. One on why role-based structures are the real enabler, the other on what happens to teams when AI starts resolving the tickets.
Here's what's planned for the evening:
17:30 - 18:00 - Arrival and first drinks
18:00 - 18:45 - AI Value Creation Starts Beyond Technology by Ralf Günthner
18:45 - 19:30 - When the Bot Takes the Ticket: Keeping Teams Effective as AI Rewrites the Rules by Dagmar Muth
19:30 - 20:30 - Networking, Open Space & More drinks\*
**AI Value Creation Starts Beyond Technology**
Many companies are currently investing heavily in AI agents, copilots, and automation, yet the expected gains in productivity and innovation often fail to materialize. The reason is rarely technological, but structural: classic hierarchical organizational models are not designed to collaborate effectively with learning, adaptive systems.
This keynote explains why role-based work is the decisive enabler for successful AI adoption. In role-based organizations, responsibilities are clearly defined, decision rights are decentralized, and collaboration is dynamically organized, exactly the conditions under which AI agents can deliver maximum value.
Drawing on current research (including McKinsey, MIT CISR, and Harvard Business School) and practical examples from industry, mechanical engineering, and chemicals, the keynote shows how companies can combine AI agents with role-based structures to:
* drastically shorten implementation timelines
* increase acceptance and trust in AI
* enable continuous optimization instead of one-off pilot projects
* significantly improve the ROI of AI investments
The core message: AI does not transform organizations, organizations determine whether AI creates impact. Those who invest today in role-based ways of working, shared leadership, and decentralized decision logic build the operational foundation to not only introduce AI, but scale it strategically.
**Ralf Günthner**
Ralf Günthner is a transformation expert, entrepreneur, and lecturer with over 25 years of experience in digital transformation, AI, IoT, and organizational development. In his keynotes, he shows why AI value creation does not emerge from algorithms, platforms, or tools, but from leadership, culture, decision-making logic, and effective collaboration.
He combines deep technology expertise with systems thinking, neuroscience, and hands-on transformation work. As Co-CEO of Team-Factory GmbH, he supports companies in anchoring AI strategically, creating orientation, and delivering sustainable impact, beyond hype and technology fixation.
**When the Bot Takes the Ticket: Keeping Teams Effective as AI Rewrites the Rules**
AI agents are starting to resolve incidents, write code, and close tickets. That's great for throughput, but what happens to the humans in the team? Motivation, ownership, skill development, and psychological safety don't disappear as team development topics just because productivity metrics go up.
In this talk, Dagmar Muth draws on her work with engineering and product teams navigating AI-driven transformation. She shares what it takes to make AI integration work for the whole team: how to preserve ownership and purpose, keep accountability clear, and build the patterns that distinguish teams that thrive from those that merely adapt.
You'll leave with a clear mental model for thinking about team health in AI-augmented setups and concrete questions to bring back to your own team or organization.
**Dagmar Muth**
Dagmar Muth is a systemic organizational developer and agile coach with 20 years of experience guiding teams and companies through transformation. As a co-worker of pragmatic solutions ag in Zürich, she supports organizations in finding the right setup, processes, and culture to sustain performance from vision to go-live, increasingly in contexts shaped by AI. She works with cross-functional tech and product teams, coaches leaders, and lectures on agile project management at SIB. Her particular focus right now: how organizations integrate AI without losing what makes their teams actually work.

Zielstrebig zur Schweizerischen Antwort auf Miro mit Collaboard
**In diesem Beitrag schildert der Collaboard-Geschäftsführer Michael Görög die Aufholjagd seines kleinen Teams gegen etablierte internationale Wettbewerber, die teils Jahre Vorsprung hatten. Und wie daraus eine starke, souveräne und sichere Alternative zu Mural und Miro wird, die beim Gebrauch auch noch Spass macht.**
Collaboard begann mit dem Aufstieg agiler Arbeitsformen und aus dem Wunsch, interaktiv an elektronische Whiteboards zu arbeiten. Der ursprüngliche Fokus lag daher auf einer Whiteboard-Software für interaktive Displays, um Meetings und Workshops im physischen Raum digitaler und interaktiver zu gestalten.
Aber mit der Pandemie veränderte der Markt sich radikal. Über Nacht brach der ursprüngliche Product-Market-Fit von Collaboard in sich zusammen: Statt digital unterstützter Zusammenarbeit im gemeinsamen Büro oder Sitzungszimmer war jetzt Remote-Work angesagt.
Das Collaboard-Team stand damit vor der radikalen Herausforderung, innert kürzester Zeit aus der elektronischen Whiteboard-Software ein digitales Whiteboard für Remote-Zusammenarbeit zu entwickeln.

[Michael Görög](https://www.linkedin.com/in/michael-gorog/) ist Co-Founder von [Collaboard](https://www.collaboard.app), einer in der Schweiz entwickelten Online-Whiteboard-Lösung für visuelle Zusammenarbeit. Mit über 16 Jahren Erfahrung in der Softwarebranche treibt er Innovationen im Bereich visueller Teamarbeit voran. Sein besonderer Fokus liegt dabei auf Sicherheit, Datenschutz und dem Einsatz moderner Technologien wie KI.

Zürich Poolside Chats : UX · Product · Research
### **Poolside Chats: Design, Research, Engineering & UX**
Join us for a relaxed summer gathering at one of Zurich’s local Badis.
This is a casual community meetup for designers, researchers developers, product managers, and other curious builders who enjoy thoughtful conversations, sharing ideas, and spending time outdoors.
We’ll gather by the pool to discuss topics such as:
* Passion projects
* Design, technology, and product thinking
* Ethical and responsible uses of AI
* Creativity, learning, and experimentation
* Personal philosophies and ways of working
* Interesting questions about the future
The format is intentionally informal. Feel free to join a conversation, listen, ask questions, or share something you’ve been exploring.
Need a break? Take a swim, cool off, and come back with a fresh perspective or a new idea to discuss.
This is not a recruiting event, job fair, or transactional networking meetup. While meaningful professional relationships may naturally develop over time, the purpose of the gathering is not to find clients, hire employees, or look for your next job. Instead, the goal is to create a welcoming space for genuine conversation, intellectual curiosity, and human connection.
Bring your curiosity, a towel, and whatever ideas have been occupying your mind lately.
\*Come to exchange ideas, not business cards.\*

How to Take Control of YOUR Mental Health
It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind.
Find out what the reactive mind is, and in the process find yourself.
Here is the secret of being positive and free:
Thinking positively is not enough.
You also have to get rid of the negative thinking.
Your mind is like a garden.
You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden.
A positive thought is like a flower in your mental garden, and a negative thought is like a weed.
You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there.
So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out!
The Meetup event will be led by a consultant who had helped many people live happier in life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Dianetics & Scientology life improvement center.
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.
The Non-competitive Tennis Partner Program
We connect you with up to 30 Men or Women tennis partners close to your PLAYING REGION and skill level. This program is less competitive, no champions crowned, no league standings just dedicated tennis partners who want to meet up with you on the courts. Players will meet up to play a tennis match or just to hit around. Just go through the [Join Page](https://www.tenniscolumbus.com/partner-program) to enter this program.

**New to electronics or curious about tinkering?**
You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building.
While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.
