Walk into a bookstore’s self-help section , rows of productivity systems : Getting Things Done, Bullet Journal, Zettelkasten. Each promises transformation—if you commit weeks. The market thrives , hundreds of new titles annually. But something new is emerging. We’re discovering we can redesign workflows instantly with AI prompts instead of studying methodologies for weeks. Three recent experiments hint at what’s coming. First, Paper2Agent transforms research papers into working code agents in 30 minutes to 3 hours. Ask it to implement AlphaGenome’s genomic analysis from a published paper & it processes the code, builds the environment, runs the tutorials. Previously: read the paper (2 days), understand the methodology (1 day), code the implementation (3 days). Now: point AI at the repository, get a working agent by lunch. Second, when I discovered Google’s Agent Development Kit research on tool design patterns, I asked AI to redesign my automation tools following those principles. The result : a 41% reduction in AI operation costs, implemented while I was answering emails in another browser tab. Third, over the weekend I read Jesse Vincent’s architect/implementer workflow via Simon Willison’s write-up. The approach splits AI coding into two sessions: one architect to design, one implementer to execute. No weeks of trial & error to understand the nuances. Read, implement, test, done. The pattern emerging : instant implementation. We can now test productivity systems like trying coffee drinks. Monday : architect/implementer (cappuccino—structured , classic). Tuesday : traditional single-session (flat white—simpler , maybe better?). Wednesday : hybrid workflow (chai latte—wait , is this even coffee?). By Thursday , the data shows which saves 3 hours per week. The self-help aisle promised transformation through commitment. AI promises transformation through experimentation.

70+ startup investments while still playing in the Bundesliga. 🤯 In 2014, Mario Götze scored the goal that made Germany world champions. In 2026? He’s still playing Bundesliga football, while building a second career that I find almost as fascinating. Through his investment company Companion-M, Mario now has: → 70+ angel investments → 15+ investments in VC funds → A focus on tech, AI, cybersecurity and health → Typical investment tickets of €25,000–€50,000 And there have already been some pretty big wins. Parloa is now valued at around $3 billion. Flatpay has also reached unicorn status. In 2025 alone, companies in his portfolio raised more than €600 million in follow-on funding. But what I find even more interesting is how this journey started. In 2020, Mario suddenly found himself without a club. At the same time, Covid hit and his son was born prematurely. Looking back, he describes that period as the moment when he really started asking himself: What actually comes after football? What started with individual investments has since developed into a professional setup with its own team, a clear strategy and a strong network. And Mario doesn’t just want to provide capital. His ambition is to create real value for founders through his reach, network and connections to potential customers and co-investors. I think there’s a great entrepreneurial lesson in that. Many professional athletes only start thinking about their second career when the first one is over. Mario is building his second one while still living his first. Maybe that’s exactly the point: Don’t start building something new when you suddenly need it. Start while you still have the freedom and time to build it properly. From footballer to entrepreneur: Mario Götze. ⚽️📈 Which “from soccer player to entrepreneur” story should I post next?

wundertaxAPI: Powering tax solutions on your platform! After successful integrations with Vermietet.de (von ImmoScout24) and other partners for the property tax return, we’re excited to open up our income tax software as an API! Our mission has always been to make taxes simple and now with the experience of over 1 million submitted tax returns, we are extending that capability to other platforms. With our API, partners can seamlessly integrate digital tax filing directly into their own products, offering customers a smooth and compliant (pre-filled!) tax submission experience without leaving their app. Think of the recent eSIM providers in neobanks! We're currently running a few pilots and are looking for more to test it: 💡 B2C platforms that want to simplify taxes for their users 💳 Fintechs & Insurtechs that want to enhance their product offerings (you already have most of the data needed) 🧾 Taxtech and Accounting providers that want to speed up time-to-market with a proven tax engine. If you’re building something where taxes play even a small role, let’s talk!
