I'm proud to announce one of my newest angel investments: Bluesphere. Bluesphere (https://bluesphere.health) is a Berlin-based health technology company building software for patients and doctors to predict, prevent, and stop disease at scale. This investment is deeply personal — I'm backing a close friend, a doctor, and someone taking the leap to become a tech entrepreneur. I first met Arne, the founder of Bluesphere, in 2013 during my Wunderlist days. He was a specialized pain physician, while I was dealing with severe back pain under constant founder pressure. Looking back, it was the result of bad habits, little exercise, and chronic stress. Arne once wrote a short note about me: “potential anxiety patient.” I ignored it and went back to work. After selling Wunderlist to Microsoft, life hit hard. I became a dad, received a cancer diagnosis, and went through an intense emotional phase. Instinctively, I started meditating and exercising regularly — and after about a year, I felt better than I had in a long time. In 2022, while running Pitch, I met Arne again after experiencing panic attacks. I pushed through one last phase of work and burned out completely. I spent five months in burnout clinics, and Arne supported me every single day. Over time, he became a mentor and a close friend. We talked endlessly about neuroscience, new clinical research, nervous system regulation, and emerging treatments. During my recovery, I met hundreds of people going through similar struggles — teachers, founders, nurses, parents, doctors, lawyers, even children. That's when it clicked: no one is immune. For most people, it's not if — it's when life stress overwhelms the system. For some it's trauma, for others work, illness, or a tragic loss. The scale of this human problem is still massively underestimated. In the U.S. alone, around 23% of adults have a clinical mental health diagnosis, and broader surveys suggest close to 50% experience significant symptoms. Many patients who experience pain aren't broken — their central nervous system is overloaded. Once you experience this yourself, a fog lifts. You realize how many people are chronically stressed, self-medicating, addicted, smoking, drinking, gambling, or simply exhausted. Health isn't just mental or physical — it's the product of decades of good and bad habits. Bluesphere's mission is to solve this problem by building the first truly holistic health platform — connecting daily habits, biomarkers, patients, doctors, and AI. Not to treat disease once it's too late, but to maintain health continuously. Bluesphere is currently raising a pre-seed round. If you're an investor, operator, or clinician excited about preventive, data-driven healthcare, feel free to reach out. Arne — thank you for your friendship, your guidance, and for having the courage to turn medical insight into a company that could help millions. It's inspiring to see your journey from doctor to founder.

Congrats to Max, Björn & Dan from Hades Mining on raising €15M in seed funding! It’s encouraging to see European investors taking bigger risks to invest in a more resilient future. Super excited to welcome Headline & HV Capital! Today, Europe produces only about 5% of the critical minerals it consumes — while demand continues to rise sharply. Hades’ laser-drilling technology dramatically improves drilling economics and unlocks European projects that were previously not viable. Combined with strong regulatory momentum through the CRMA and national energy strategies, the team is stepping into one of the most strategically important industrial opportunities of the decade.

Max is a one-of-a-kind founder. When we first met him, he didn’t have a co-founder – just a notebook full of wild ideas. Each one was more ambitious than the last. But one stood out: to build a next-generation drilling company in Europe – one that makes drilling not only safer but also environmentally responsible. At the time, it sounded almost impossible. Then, just weeks after he got started, China began restricting exports of rare earth elements to the US and Europe. Suddenly, what seemed like a crazy idea became one of the most critical industrial startups in Europe. At Interface Capital, we’re proud to back founders like Max – people who don’t just react to the future, but drill straight into it. Go Hades Mining!

Today we’re introducing 20+ new AI Actions in Pitch to make every slide clearer, more consistent, and visually stunning. The team has worked incredibly hard this year to prepare a series of bold AI releases – and this is just the first step. I’m very excited about what’s coming next.

Neel is one of the best founders I’ve ever met, and Popcorn is an outstanding product. If you’re looking for a great opportunity in Customer Support, you should definitely apply.

As an investor, I look for founders who are authentic technologists, scientists, and artists – builders with an unreasonable amount of hunger, knowledge, resilience, and purpose. While LinkedIn often celebrates success, I want to highlight a company that’s still in the fight: Litona GmbH, founded by two brilliant battery scientists, Tom Boetticher and Sebastian Büchele. When I met Tom in early 2024, he ran Europe's fastest-growing YouTube channel on battery tech. He told me he was starting a company to build sodium-ion batteries made entirely from European materials. Niklas and I were incredibly inspired by their ambition and decided to back them – funding their first lab. Since then, Europe’s battery industry has been collapsing. Investors have lost faith. Competing with China seems impossible. Yet Tom and Sebastian refuse to give up – instead, they opened up to their community, sharing their challenges with radical honesty. Now people are rallying behind them. Will it work? Time will tell. But this relentless authenticity – the courage to keep building when no one believes – is what makes the best founders. This journey reminds me of Mate Rimac, who struggled for nearly a decade before Porsche and Hyundai invested – and he went on to take over Bugatti. 👉 https://lnkd.in/dzdd9dEV

Last week, publicly traded software companies lost roughly $1 𝘁𝗿𝗶𝗹𝗹𝗶𝗼𝗻 𝗶𝗻 𝗺𝗮𝗿𝗸𝗲𝘁 𝘃𝗮𝗹𝘂𝗲. Over the past 20+ years I’ve had the privilege of building software and investing across several major platform shifts: from local software distributed on floppy disks with one-time license fees, to cloud-based SaaS with seat pricing, to fully cross-platform, real-time synchronized apps. What we are seeing happening right now is another giant platform shift 𝗳𝗿𝗼𝗺 𝗦𝗮𝗮𝗦 𝘁𝗼 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗦𝗼𝗳𝘁𝘄𝗮𝗿𝗲. Historically, building and scaling successful software companies required millions in capital, large engineering teams, complex architectures, and years of operational execution. Defensibility largely came from execution complexity, software was hard. Well, that’s over. With the arrival of advanced models such as Codex 5.3, Opus 4.6 and other frontier systems, we are reaching a point where developers manage coding agents instead of writing code themselves, and entire products can be built with dramatically smaller teams. The barrier to creating high-quality software is collapsing faster than expected. At first glance, this shift feels existential for the software industry. If anyone can build software, is software itself becoming commoditized? Will defensibility disappear? Will successful products be instantly replicated by AI? 𝗪𝗵𝗮𝘁 𝗶𝘀 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗵𝗮𝗽𝗽𝗲𝗻𝗶𝗻𝗴 — 𝗮𝗻𝗱 𝗵𝗼𝘄 𝘀𝗵𝗼𝘂𝗹𝗱 𝗯𝘂𝗶𝗹𝗱𝗲𝗿𝘀, 𝗳𝗼𝘂𝗻𝗱𝗲𝗿𝘀, 𝗶𝗻𝘃𝗲𝘀𝘁𝗼𝗿𝘀, 𝗮𝗻𝗱 𝗲𝗺𝗽𝗹𝗼𝘆𝗲𝗲𝘀 𝗶𝗻 𝗺𝗼𝗱𝗲𝗿𝗻 𝘀𝗼𝗳𝘁𝘄𝗮𝗿𝗲 𝗰𝗼𝗺𝗽𝗮𝗻𝗶𝗲𝘀 𝗮𝗱𝗮𝗽𝘁? For decades, software was something humans logged into and operated. The next generation — 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗦𝗼𝗳𝘁𝘄𝗮𝗿𝗲 — will still be configured by humans, but will increasingly run continuously in the background, operating workflows 24/7: generating invoices, writing and deploying code, running marketing campaigns, analyzing data, coordinating operations across systems, managing machines, and handling customer support. Instead of selling tools used by employees, many companies will effectively deliver 𝗲𝗻𝘁𝗶𝗿𝗲 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝗳𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝘀 𝗮𝘀 𝘀𝗼𝗳𝘁𝘄𝗮𝗿𝗲 — faster, cheaper, and continuously improving. Pricing models will gradually shift from seat-based subscriptions toward usage- and outcome-based economics, while the teams building these products become dramatically smaller and more productive than ever before. Every major platform transition reshapes how companies are built, how products are priced, and where value accrues. The shift toward agentic software may be the most profound platform transition the industry has experienced yet. PS: I’m deeply concerned about what this transition means for entry-level jobs. Our top priority should be to fund large-scale initiatives focusing on understanding how our societies, education systems, and economic models must adapt if a significant share of knowledge work can and will be automated by AI.

🇪🇺 We’re excited to announce our latest European deep-tech investment: Willo. Willo is building technology that enables phones, laptops, robots, and other hardware to charge wirelessly — even while moving — removing the need for cables or precise charging alignment, a foundational capability for the next generation of autonomous infrastructure. We’re grateful to support Harri Santamala, Nam Ha-Van and Marko Voutilainen as they move the technology from early breakthroughs into real-world applications. Looking forward to the journey ahead together!

Andreas deserves a statue as high as the Statue of Liberty if he succeeds.🗽 EU–INC will impact Europe forever.
