Yatta

Companies aren’t built on business models alone. They start with a reason, a problem worth solving, and a belief that things can be done better. This week, we had the opportunity to share that story when we opened our doors 🚪 in Kassel as part of “Unternehmenskultur vor Ort”, hosted by IHK Kassel-Marburg and Werte-Netzwerk e.V., in collaboration with IT-Netzwerk Nordhessen e.V. and Science Park Kassel GmbH. Johannes and Manuel took our guests back to Yatta’s beginnings 🌱 from the cross-university Fujaba research project, led by Prof. Albert Zündorf among others, to the first steps as a company working with investors and customers, and to what Yatta has become since. Together, we discussed how vision and values shape our culture and guide our everyday work. Not as abstract statements on a wall, but as something you can see in how people work, how decisions are made, and what a company creates. That’s what we wanted to show our guests. Take a look and see how the day unfolded. 📸

What does a values-driven tech company look like from within? On 24 June 2026, we’re opening our doors in Kassel. 🧑💻 During #Digitaltag 2026 and as part of “Unternehmenskultur vor Ort”, we invite you to explore our offices, meet our team and co-founders, and ask us what usually stays behind the scenes: 🌐 How do values shape the way we build software? 🤝 How do they influence collaboration, decisions, leadership, and engineering? 💡 And why do founder-led companies often start with more than a business model—but also with a problem worth solving and a better way of working? 📍 Open Day in Kassel 📅 24 June 2026, from 16:00 📌 Science Park Kassel, Universitätsplatz 12, 34127 Kassel The event is hosted by IHK Kassel-Marburg, Werte-Netzwerk e. V., and IT-Netzwerk Nordhessen e.V., in collaboration with Science Park Kassel GmbH. Register here: https://lnkd.in/e8z4dVXk We look forward to seeing you! 🤗

Digital ticketing update: our Platform now has official VDV-KA certification, Germany’s framework for electronic ticketing in public transit.🚊 🤓For those who aren't public transportation experts, VDV-KA defines how the Deutschlandticket and most other tickets in Germany are issued, verified, blocked and reconciled across hundreds of participating operators, using a public-key infrastructure of cryptographic keys and shared product definitions. Shoutout to our teammates who carried the big pile of certification papers📑through—and to everyone else involved! Also, special thanks to the team at VDV eTicket Service GmbH & Co. KG.🙏

Two days ago, .de domains experienced a severe incident. The root cause was a technical issue within the Domain Name System (DNS) infrastructure related to the .de zone operated by DENIC eG. https://lnkd.in/dEfZzg7c The Yatta Platform including Yatta Checkout and our website were also affected. We sincerely regret the inconvenience this caused and want to apologize to our customers and users. 🙏 Based on the information available, the incident was related to faulty DNSSEC data. As a result, many systems were temporarily unable to correctly validate the resolution of .de domains. Numerous websites and web services, including our platform services and fallback systems, were temporarily unavailable. DENIC resolved the issue during the night. Our team also spent intensive hours dealing with the incident throughout the night of 5-6 May. We're now carefully reviewing the event and taking several actions to further strengthen the resilience of our systems against disruptions affecting critical infrastructure components. Going forward, our services and our website will also be available at yatta.com. 😉 Cloudflare has published a detailed technical analysis of the incident here: 👉 https://lnkd.in/dttaTeED This incident once again highlights how deeply interconnected today's digital systems are, and why resilience, redundancy, and continuous improvements are key foundations of a modern digital infrastructure. We'd also be interested to hear from you: how were you affected by the .de outage, and, if you're in the tech industry, what do you do to mitigate failures of critical infrastructure components? #DNSSEC #DNS #DENIC

Open source works because development progress goes upstream. One fix serves thousands; improving one product can elevate the whole open-source ecosystem. One such product is Vector Systems Engineering Solutions's PREEvision, a systems engineering tool for automotive development🚘. It runs on Eclipse, along with thousands of other products across engineering disciplines. When it ran into limitations in the platform itself, we worked with Vector to fix them at the source👷: ⁍ HiDPI rendering ⁍ Embedded browser ⁍ Diagram scaling The changes shipped in the Eclipse 2025-06 release as the default. Every product built on the platform benefits.💪 Read more here: https://lnkd.in/drKYdsp9 #OpenSource #Eclipse #SoftwareEngineering #SoftwareDevelopment

Last week, we welcomed Bundestag members Esther Dilcher and Daniel Bettermann to our headquarters in Kassel for a candid exchange on Germany’s present—and its future. We spoke about what it takes to build technology companies that don’t just start, but scale globally. 🚀 Germany does not lack talent. What too often holds us back are the conditions around it: too much bureaucracy, too little growth capital, and—more importantly—too little ambition. If we are honest, this is not just a policy problem. It's a mindset problem. So we need to raise our standards again: • Work harder • Aim higher • Compete internationally—with the ambition and will to succeed At Yatta, our co-founders Johannes Jacop and Manuel Bork hold us to that standard. We expect a lot—from ourselves and from our team. Because building meaningful software that truly works and inspires in the real world requires discipline, ownership, and continuous improvement. Germany has grown too comfortable with "(not) good enough". That mindset holds us back. There is much to learn from environments where building the seemingly impossible is the norm. We need: • Less hesitation, more curiosity • Less perfectionism, more iteration • Less fear of failure, more willingness to learn Digital sovereignty will not be achieved through protectionism or hesitation, but through excellence—built on hard work, talent, and superior products. 👉 Better framework conditions matter—but so does a stronger mindset: the will to build, to improve, and to take responsibility for results. Thank you Esther Dilcher and Daniel Bettermann for the open and thoughtful conversation. 🙏 We need fewer reasons why things are difficult—and more people willing to make them work. 💪

📰 HNA Hessische/Niedersächsische Allgemeine, the leading regional newspaper in Northern Hesse, published an interview with our co-founders Johannes and Manuel last week. We talked about our startup journey, what it takes to build a company over time, and why success rarely comes from a single “genius moment,” but from strong teams, persistence, and execution over many years. 👉 Read the interview (in German) here: https://lnkd.in/dxmyYfA3

Mike Tyson once said, “Everyone has a plan until they get punched in the face.” 👊 Sometimes things don’t go as planned, and that’s okay. What matters is how we adapt, keep our balance, and move forward. 🏄 🌞 On one of the last days of summer, we took that spirit to the lake — waterskiing, wakeboarding, paddleboarding, canoeing, and a few bold flips at the Aqua Park. 152 of us — teammates, friends, and family — came together to celebrate how far we’ve come and what lies ahead. Read the full story, “Making waves and moving forward,” in the first comment. 👇
