About this episode
Finding Product Market Fit is one of the biggest challenges for founders. It's the crucial moment when product and market align perfectly, enabling sustainable growth. But how do you find this sweet spot?
Nine successful German female founders share their most valuable learnings and practical hacks on Product Market Fit. Among them: Julia Bösch, who built Outfittery to over one million customers, Kati Ernst from the fast-growing bootstrapped D2C brand ooia, and Laura Bornmann, Managing Director at STARTUP TEENS.
Key Insights from the Experts
Test Before You Build
A central point emphasized by multiple founders: Test your ideas before you fully develop them. Those who complete their product without gathering feedback first risk building past the market. Instead, founders should speak with potential customers early and frequently.
Customer Feedback as Your Compass
Customer feedback plays a crucial role in creating a market-ready product. The interviewed founders use various approaches:
- –Direct conversations with target audiences
- –Early prototypes and MVPs
- –Continuous iteration based on user feedback
- –Observing usage behavior rather than just conducting surveys
Personal Growth as a Leader
An often overlooked aspect: Founders must grow alongside their product. The Product Market Fit discovery phase demands that leaders continuously expand their skills and adapt to changing requirements.

The search for Product Market Fit isn't a one-time event, but a continuous process. The interviewed founders demonstrate: those who test early, listen to customers, and grow personally have the best chances for sustainable success.
