Donderdag 21 mei 2026 is het weer tijd voor onze Techday: hét vaste moment waarop we kennis delen, elkaar inspireren en nieuwe ideeën direct in de praktijk brengen. Deze editie pakken we het aan als een conferentie in het klein. Drie sprekers, drie verhalen, één middag – drie verhalen voor de prijs van één. Wat kun je verwachten? **Dirk neemt een kijkje onder de motorkap van AI** AI voelt voor veel mensen als magie. In deze talk probeer ik de magie weg te nemen door een kijkje te nemen onder de motorkap. Een essentieel bouwblok van moderne AI is een neuraal netwerk. Als je begrijpt hoe een neuraal netwerk werkt, is het een stuk makkelijker om te begrijpen hoe en waarom een LLM werkt. De beste manier om iets te begrijpen is door het te bouwen, vanaf scratch. Dus dat gaan we in deze talk doen. Door dat te doen leren we over artificial neurons, activation functions, backpropagation en meer. **George vertelt hoe AI Cyberaanvallen verandert** George Schizas (extern), voormalig IT Manager, nu werkzaam als CISO, vertelt over zijn ervaringen in de Cloud Cyber Security en hoe hackers met behulp van AI nieuwe aanvalsmethoden kunnen gebruiken om kwetsbaarheden op te sporen en te exploiteren. Hij geeft voorbeelden van manieren om in Kubernetes omgevingen in te breken en noemt manieren om dit tegen te gaan. **Roland duikt in de wereld van de fraude fabriek** Als ontwikkelaar kom je dagelijks in contact met technologie en de laatste jaren natuurlijk ook vaak met AI. JIJ snapt heel goed wat de voordelen en de gevaren zijn, maar hoe leg je complexe onderwerpen als AI gegenereerde afbeeldingen, Voice Phishing en Hallucinaties uit aan je ouders, de buurvrouw, of je kinderen? Ik neem jullie mee in een realistische situatie waarin Anna en haar familie opgelicht wordt met behulp van verschillende technieken en hoe dit oplichters-landschap met behulp van AI verandert. **Wanneer:** Donderdag 21 mei 2026 **Wat:** Techday – conferentie-editie “AI kansen en valkuilen” **Voor wie:** Iedereen (!) die nieuwsgierig is en wil leren **Agenda** 14:45 - 15:00 - Inloop 15:00 - 16:00 - Neurale netwerken 16:15 - 17:15 - AI risico’s en kansen 17:15 - 18:00 - Eten 18:00 - 18:45 - Fraude fabriek We zien je graag op de Techday!

She knows the challenges that UX teams face in demonstrating their added value from her 10+ years of experience at the tech start-up Blendle, cybersecurity scale-up Zivver, and low-code SaaS Mendix. She now helps teams with gaining a competitive edge through inclusive research and co-creation “from a to y”. Her talk will point you to the importance of user experiences that are not reflected in the training data of LLMs and the “curb cut”-effects to be gained which no synthetic persona will provide. **Speaker 3: Bo Kusters** Service Designer at the Dutch Tax Administration. With millions of users, the team often sees the same generic functional and emotional needs recurring in their user research. To avoid reinventing the wheel every time, they developed an interactive, tarot-style card game. With this clever deck, they make complex user insights tangible, allowing internal teams to apply this data directly in their daily work. Learn during this session how to successfully translate abstract research data into a practical design tool that actually works for your team. **Event details** **When:** May 21 \| 18:30 – 22:00 **Where:** Acato, Oudegracht 231, Utrecht **Cost:** Free \(Includes snacks & drinks sponsored by Visma \| ProActive\) **Capacity:** 50 spots Stay tuned for more updates!

In a world where new frameworks, tools, and trends seem to appear every week, it’s easy to forget where true technical strength and innovation come from: the fundamentals. At Back to the Future of Code, we invite developers to **explore the foundational building blocks behind modern software**. Three speakers will each offer a different perspective on these fundamentals and highlight why they’re still at the heart of great engineering. Talks: 🎤 **Frontend Framework Dependency: Are we skipping the hard part** → Ramona Domen (Software Engineer and Impact Leader) Ramona shows how modern frontend frameworks still depend on HTML, CSS, and JavaScript. And why mastering these foundations makes you a more deliberate and powerful engineer. 🎤 **Why Great Engineers Don’t Just Write Code** → Sarah Gruneisen (Engineering Leader & Leadership Coach ) Sarah’s talk highlights how many engineers, especially women, have their strategic and technical strengths overlooked in favor of their “people skills”. She reveals how those very skills drive real technical impact and invites us to broaden our definition of engineering excellence. 🎤 **Women in Tech: Bug or Feature?** → Maaike Wachters (Software Engineer) Maaike uncovers the hidden history of female tech pioneers whose groundbreaking ideas laid the foundation for the way we code and innovate today. **Program** * 17:15 – 18:00 Walk in and dinner (vegetarian options) * 18:00 Intro WeCode and KVK * 18:20 Talks and Q&A (in English) * 20:00 – 21:00 Snacks and drinks **Who should attend?** This event is especially designed to spotlight and elevate women’s voices in tech by giving them a place on the stage. Everyone is welcome to join. **How to get there** KVK is located at Sint Jacobsstraat 300, 3511BT Utrecht. (KVK has two buildings on the same street, so look out for number 300) * By car: Paid parking is available at Q-Park La Vie or Paardenveld. * By train: The nearest train station is Utrecht Centraal, about a 10-minute walk. * By bus: Take lines 1, 3, 6, 7 or 27 to bus stop Sint Jacobsstraat. * By bike: There are bike racks available close to the location.

Hi all, We’re back at Mick O’Connells and ready for another strong evening! We’ve got our own space again. Walk in, turn right at the bar, head past the dart boards, and you’ll find us in the side room. We've introduced a simple rotating format that gives you the chance to actually speak with everyone in the room. Short, focused conversations, good energy, and a lot more fun than it sounds. We’ll throw in a few conversation topics to get things going, but how you use the evening is entirely up to you. Come with intention, or don’t. Talk business, find clients, meet future partners, make friends, or just unwind with people who get it. We’re all building something, and we all have to roll with the punches. Only rule: you’re an entrepreneur, freelancer, or about to become one within the next 3 months. If not… the clock starts now ;) Try to arrive on time so we can kick things off properly. The activities start at 20:00! Can't find us? Look for the grey Gnome. He’ll guide you better than any sign ever could. See you there.

(english/german below) **Bitcoin Pizza Dag!** Op 22 mei 2010 betaalde programmeur Laszlo Hanyecz 10.000 BTC voor twee pizza's — de eerste gedocumenteerde aankoop met bitcoin. Hij plaatste een bericht op een forum waarin hij BTC aanbood voor pizza; een andere gebruiker ging akkoord, bestelde de pizza's en leverde ze af. Die transactie werd later bekend als "Bitcoin Pizza Day". Laszlo bewees dat Bitcoin als ruilmiddel gebruikt kan worden. **Sluit je bij ons aan voor pizza-avond bij De Pizzabakkers!

**How to Get Off-Market Deals With Direct-to-Seller Marketing** Want to learn how to get off-market deals through direct-to-seller marketing without relying on agents, wholesalers, or the MLS for consistent deal flow? That is exactly what we are covering at this next Columbus Investors Club Meetup. Get Your Free Ticket **[HERE](https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp)**[ ](https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp)🎟️ Most investors who try to do off-market deals make the same mistake: they throw money into a marketing channel, pray that it works, and hope a deal comes out the other side. There is no real strategy, no clear math, no tracking, and no process to know what is actually working. At this meetup, we are going to break down how to reverse engineer direct-to-seller marketing using our SCALE framework so you can approach your marketing with more clarity, confidence, and consistency. We will cover how to think through inbound, outbound, and free marketing channels, how to choose the right channel for your goals, how to run the numbers before you spend, how to allocate the right budget, how to launch the campaign correctly, and how to evaluate and track performance so you can make better decisions moving forward. **SCALE Framework:** **S –** Select the right channel **C –** Calculate the numbers **A –** Allocate the budget **L –** Launch the campaign **E –** Evaluate and track it **What We’ll Cover** * How to get off-market deals through direct-to-seller marketing * How to stop guessing and start reverse engineering your marketing * The difference between inbound, outbound, and free marketing channels * How to choose the right channel for your business and market * How to calculate the numbers before launching * How to allocate a budget based on goals, not emotion * How to launch and track a campaign the right way * How to create more consistent and predictable deal flow **Date:** May 28, 2026 (Thursday) **Time:** 6 - 8pm EST **Location:** Ohio Brewing Company, 421 E 2nd Ave, Columbus, OH 43201 **Save Your Seat** → https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp **FREE DRINKS & FOOD PROVIDED!** **About Columbus Investors Club** The Columbus Investors Club is a local meetup for real estate investors, aspiring investors, contractors, vendors, lenders, realtors, and other professionals who want to grow in the Columbus market.
