B Corp in reality check: What does certification really offer? (#145)

Sustainability is a hot topic—and just as often the subject of critical scrutiny. Labels, certificates, greenwashing debates: for many companies, the key question is no longer whether sustainability is important, but how it can be implemented credibly.

neosfer addressed this question and obtained B Corp certification in 2023 – and recently successfully completed recertification. One thing is clear: this is not a seal that can be obtained “just like that.” The process is intensive and affects culture, governance, and everyday decisions.

Sustainable finance in reality check: Less marketing, more substance? (#144)

Sustainable finance has long been considered one of the major topics of the future in the industry. Today, it is discussed much less frequently—in public, in politics, and often in companies as well. Energy crises, inflation, and geopolitical tensions have brought other issues to the forefront. But does that really mean that sustainability is losing importance?

Quite the contrary, says our guest Matthias Hübner from the Sustainable Finance Cluster. While the public hype is subsiding, the topic is continuing to develop in the background – in a more structured, data-driven way and with a clearer focus than just a few years ago.

Together with Dirk and Sarah, he talks about where sustainable finance really stands today, which trends are currently having an impact (both positive and negative), and why the impression that the topic is “over” is misleading.

Is Germany sleeping through the future? What professional trend research reveals about us (#143)

Germany is considered a hub for innovation—but is that still true? Professional futurologists paint a different picture. While international companies are forging ahead with AI, deep tech, and new business models, German companies are often lagging behind.

Sven Janszky from the 2b AHEAD ThinkTank has been conducting systematic futurology research for several decades. His method: strategic foresight. Based on this, he and his team invest in the startups that will shape the market of tomorrow.

Dirk and Fabian talk to Sven about the mechanisms of genuine trend research, why Germany is falling behind in innovation, and which trends will really be relevant in the coming years. From neobanks to embedded finance to AI – which developments are overrated and which are underrated?

Financial health in Germany: Are our finances in worse shape than we think? (#142)

How healthy is Germany financially? The Financial Health Initiative has measured this for the first time. The result: 52.83 out of 100 points. In concrete terms, this means that only one in three people can cope with an unexpected large expense. For many, a broken washing machine quickly becomes a problem.

The study also shows that personal financial health has nothing to do with region or gender—but a lot to do with education, age, and life situation.

Sarah talks to Emanuel Renkl from the Financial Health Initiative and Markus Lehleiter from the House of Finance & Tech about what the first Financial Health Score for Germany means, which groups are particularly at risk, and what role AI can play in this.

AI and white label: An efficiency revolution in banking? (#141)

Margins in the banking industry are under pressure. Banks worldwide invest over $650 billion in IT every year – much of which goes toward modernizing old systems. At the same time, banking-as-a-service is booming: instead of developing everything themselves, banks are increasingly renting ready-made financial services.

But does the combination of white-label solutions and AI really lead to an efficiency revolution? Or are these just exaggerated promises?

Fabian and Dirk discuss this in episode #141 with Konstantin Kavvadias, CFO of Solaris – one of the first BaaS providers. We discuss which efficiency gains are measurable, where the limits lie, and what banks need to do now to remain competitive.

Klarna debt as a trend: Why mini loans are booming (#124)

Mini loans are booming – according to the latest Schufa data, almost every second new installment loan granted is for a sum of less than 1,000 euros. With annual growth of 14 percent, they have become an integral part of the credit landscape. However, while they offer many people short-term financial flexibility, they are also heavily criticized. Young people in particular are increasingly getting into debt through excessive consumption, often through “buy now, pay later” services such as Klarna. Are mini loans a sensible solution or a dangerous debt trap? We find out in this episode with Sarah, Dennis and Kerstin Föller (Verbraucherzentrale Hamburg).

Biodiversity

Biodiversity – actually so important, but still too little discussed.

In the area of sustainability, the focus in recent years has mainly been on CO2 emissions, their reduction and climate protection. How we preserve biodiversity, simply put the diversity of species and plants on our planet, has been less of a focus.
