The Hidden Business Behind Your Apartment Search | Philipp Attensam

Finding an apartment should be simple. Yet for many people, it has become a frustrating process of endless searches, unanswered inquiries, and competition for the same few properties. But what if the problem isn't just the housing market itself, but the platforms we rely on to navigate it? Philipp Attensam co-founded Lystio to challenge how people search for homes. Since launching in March 2025, the company has grown to more than 90,000 property listings and over 1,600 real estate agents. Along the way, Philipp and his team discovered how established real estate platforms actually operate, why certain properties receive more visibility than others, and how difficult it can be to challenge an industry built around legacy business models. But the more interesting question may be whether better technology can actually make finding a home fairer, or whether it simply makes an already competitive market move faster. In this episode, we cover: • Why apartment hunting remains frustrating despite decades of technological progress • How real estate platform business models dictate which properties you see first • Why brokers pay for visibility and what that means for apartment seekers • How AI could move beyond traditional filters to understand what people actually want in a home • Whether algorithms can make housing searches fairer when hundreds compete for the same flat • What happened when Lystio challenged established competitors and faced legal threats • How Philipp built a platform with 90,000+ listings in just 18 months without coding skills • What building in a competitive industry teaches you about ambition, resilience, and personal sacrifice From the hidden economics of property rankings to the limits of technological innovation, this conversation explores who really shapes your apartment search—and whether the future of finding a home can genuinely be different.

The Second Time Is Different: Building Again After a €40M Exit | Karl Edlbauer

What changes when you build a company for the second time? Karl Edlbauer started what would later become hokify while still studying at WU. Together with his co-founders, he tested the first ideas on campus, grew the company to almost 100 people and millions of job seekers, and eventually exited at a reported valuation of around €40 million. Then, the same three founders decided to start again. In this episode of Once Upon a Student , Karl reflects on what experience really changes — and what it doesn’t. We talk about why he would raise less money today, why they abandoned a product that was already generating revenue, why hokify was sold even though an exit had never been the original plan, and how three friends managed to remain a founding team through almost a decade of company building. Today, Karl is building ONE100, entering healthcare with more experience, a stronger network and a track record, but also with different responsibilities and a very different understanding of what it takes to build a company. The second time is different. But is it actually easier?

Before You Raise Money: What Every Founder Should Know | OUAS x Entrepreneurs Talk Ep.1

Before you raise money, you should understand what venture capital really means. In this special crossover episode of Once Upon a Student x Entrepreneurs Talk, we explore what every founder should know before entering the fundraising journey: when VC makes sense, when it might not be the right path, what investors actually look for, and how founders can navigate the emotional reality behind raising capital. Together with Magdalena Möslinger-Gehmayr from PUSH VC, Hannah Wundsam from AustrianStartups, and Michael Hofmannrichter, CEO & Co-Founder of silana, we discuss venture capital from three different angles: the investor perspective, the ecosystem perspective, and the founder perspective. We talk about: • Why venture capital is not the right path for every startup • What early-stage investors look for in founders • Why the founding team often matters more than the idea • How fundraising momentum can change everything • What students and first-time founders often misunderstand about raising money • Why execution, timing, and obsession matter more than having the “perfect” idea This episode is for students, aspiring entrepreneurs, and early-stage founders who want to better understand the reality behind venture capital before they start raising money.

Learning Expert Warns: Stop Studying Hard Before It's Too Late | Lennard Klein OUAS ep.17

Every student wants better grades. Almost none of them are taught how to actually get them. Lennard Klein went from struggling student to perfect GPA using a system built entirely on neuroscience and peer-reviewed research. Not motivation, not grinding, not luck. In this episode of Once Upon a Student , he shares the exact framework he now teaches to students across Europe through his company Brain Boost. What you'll learn in this episode: · How to study for exams without burning out · Why passive studying (re-reading, highlighting, summaries) has zero scientific backing · The ideal study session length for maximum concentration and retention · How to go from bad grades to top of your class · Lennard's student did it in one semester · The mindset shift that separates students who improve from those who stay stuck This episode is for students who are tired of working hard with nothing to show for it, parents looking for proven learning strategies for their kids, and anyone who wants to understand how the brain actually processes and retains information. The science exists. It's been there for 200 years. Now you know where to find it. 🎙️ Once Upon a Student | Guest: Lennard Klein, Founder of Brain Boost

Why Equal Opportunity Is a Lie (And It Starts Before School) | Rosa Bergmann OUAS ep.16

In this episode of Once Upon a Student, we sit down with Rosa Bergmann — social entrepreneur, former teacher, founder of Hobby Lobby, Teach For Austria alumna, and nominee for Austrian of the Year. Rosa has seen inequality where most people stop looking. Not just inside classrooms, but long before and long after them. She argues that the biggest educational gaps are often inherited, shaped by family background, language, money, attention, environment, and everything that happens once the school bell rings. What started as frustration in a Viennese middle school turned into a mission. After meeting children who dreaded weekends and holidays because school was the only stable place in their lives, Rosa realized how much opportunity depends on what families can afford outside the classroom. That insight became the foundation for Hobby Lobby — an organization that now reaches thousands of children and gives them access to experiences, creativity, mentorship, and support they otherwise might never get. But this conversation also breaks another illusion: that NGOs are somehow less serious than “real businesses.” Rosa explains why social impact cannot be built on good intentions alone. If you want to change lives at scale, you need to build with the same discipline, structure, and professionalism as any high-performing company. Today, she leads a growing organization with a multi-million-euro budget, a large team, and a model designed for long-term impact. This conversation goes far beyond education policy. We talk about inherited inequality, the hidden power of after-school life, the impossible pressure placed on teachers, why schools still look like they belong in 1950, what it means to build a serious impact organization, and why the world’s biggest problems are too often treated like side projects. If you are a student, founder, future leader, or someone who wants to build something that truly matters, this episode will challenge the way you think about fairness, responsibility, and what real impact actually requires.

You’re Ignoring the Opportunities: How Cornelia Daniel Built Austria’s PV Future | OUAS ep.15

What if the biggest opportunities are already right in front of you? In this episode of Once Upon a Student, we sit down with Cornelia Daniel, founder of Dachgold and one of Austria’s leading voices in renewable energy. While many of her classmates were preparing for traditional careers in consulting and banking, Cornelia followed a different path. What started as curiosity during her master’s thesis turned into a mission: bringing photovoltaic systems to rooftops across Austria. But building a company in an industry that barely existed wasn’t easy. When Cornelia started, the solar market in Austria was still developing, regulations were uncertain, and most companies didn’t yet see the opportunity. Today, she has helped equip hundreds of rooftops with solar energy, shaped the renewable energy conversation in Austria, and was named Austrian of the Year. This conversation goes far beyond solar energy. We talk about curiosity, entrepreneurship, perseverance, and why some of the best opportunities appear long before the world is ready for them. If you’re a student, aspiring entrepreneur, or someone trying to figure out your path, this episode will challenge the way you think about opportunity, timing, and following your curiosity.00:00 – Intro "You will never again have so much time"01:11 – From Safe Career Plans to an Entrepreneurial Path04:36 – The Moment She Discovered Her Big Opportunity07:38 – The Decision to Start a Company12:25 – Why Founders Often Ignore Simple Ideas19:03 – Thinking Big: A Mission Beyond Just a Company26:07 – The Emotional Rollercoaster of Entrepreneurship31:09 – Navigating Uncertainty, Politics & Market Changes44:51 – How AI Is Changing Entrepreneurship49:45 – Austrian of the Year & Advice for Future Founders
