In this episode, we are joined by Christian Nentwich, founder of Duco, a B2B data automation company valued at over $100 million.

Christian shares how he started his first business, how he entered the world of fintech, the challenges he faced while scaling a company, and the mistakes he made that, if avoided, could have accelerated Duco’s growth.

He also explains why B2B fintech is one of the best, yet most difficult businesses to be in, and why being exceptionally good at sales, along with having resilience and a never-give-up attitude, is crucial when dealing with $100K+ ticket-size deals.

What makes his story even more compelling is that both startups he founded were ahead of their time, offering cloud and automation solutions when banks and financial institutions weren’t ready. Duco nearly failed before a major market shift in 2015 turned the tide.

If you’re building in fintech, SaaS, or enterprise tech, this episode is full of deep insights and actionable lessons from someone who's been through it all.
