How to Choose an Office That Reflects the Culture You Want to Build, Not Just the One You Have Today
Most founders choose their first office based on who they are today. The problem is, companies evolve faster than spaces do. This piece explores how offices shape behaviour, culture, and team dynamics, and why designing for who you are becoming matters more than fitting the present.
From Sushi Bars to 40 Million Downloads: The Verena Pausder Story
At the latest edition of Gründerszene × The Delta, Verena Pausder shared the full story behind Fox and Sheep from a sushi restaurant in Bielefeld nobody asked for, to a pivot that could have gone wrong, to 40 million paid downloads and an exit that opened the next chapter. It is a founder journey built not on a perfect idea, but on the willingness to keep going when the original plan stopped making sense.
Validation Plans That Actually Work: How Founders Can Test Their Ideas Before Spending Money on Development
Validation often gets treated as a quick checkbox before building begins. A few conversations, some positive feedback, and it feels like enough to move forward. But real validation is not about hearing that an idea sounds good. It is about understanding whether the problem is real, whether people are willing to act on it, and whether it is strong enough to support a business. The founders who get this right are not looking for reassurance, they are looking for truth, even when it challenges what they want to build.
Your AI Doesn't Know Enough About Your Business
Most organisations start from zero every time they open an AI tool. Fast outputs, articulate responses, completely generic results. The fix isn't better prompting. It's giving your AI something to work with before you ask. That's the shift from prompt engineering to context engineering: building a structured knowledge layer your AI can draw on, not a document dump, but a deliberate representation of how your company works. The organisations getting real value from AI aren't the ones with the best prompts. They're the ones whose AI already knows what it needs to know.
The AI Native Economy: From Software to Services with the 3H Model
For two decades, venture capital believed proprietary software created defensible moats. Today, that moat is dry. The next era belongs to founders who abandon software licensing and deploy autonomous agents to sell outcomes, not tools. Here's the framework to identify which service verticals are ripe for disruption.
The 2026 Product Stack: What Tools the Smartest Early-Stage Founders Are Actually Using
Too many tools, not enough clarity. The best founders are not building bigger stacks, they are building sharper ones. In 2026, the advantage is not access to software, it is knowing what to use, when to use it, and when to let it go. A well designed product stack is not about complexity or trend chasing. It is about creating leverage while keeping decisions clear, fast, and reversible.
The Future of Startup Events: Creating Experiences, Not Just Agendas
Startup events are no longer about packed agendas and scheduled networking. Founders are looking for experiences that create real connection and momentum. This piece explores how experience design, environment, and community are reshaping what meaningful events look like.
The 5 Things Most Founders Forget When Moving Into Their First Office (And Why They Matter)
Your first office might look complete, but that does not mean it works. From acoustics to layout to infrastructure, small oversights quickly compound once teams start working together. This piece breaks down the patterns that quietly create friction and how to design a space that actually supports how teams operate.
