Interview with zinsbaustein.de

What inspired you to found your startup?

The crowdfunding investment idea originated in the US. Our founding investors, Sontowski Partner and finleap, added their core competencies as real estate developers and digital company builders, and started zinsbaustein. 2016 was the perfect time.

How are you different? What is your unique value proposition?

We only offer high-quality real estate debt investments. We offer one risk class and select only investment opportunities with excellent chances for success. We have transparent processes and a very experienced investment committee to ensure that all of our offers have the quality level we promise.

How do you define success for yourself and your company?

We want to build a solid and long lasting real estate investment platform. Hence, we want to offer trustful and high-quality investment opportunities for a wide variety of investors. We want to be the best platform and not necessarily the biggest platform. The success of our customers is our success.

What do you want to achieve next year?

We want to increase the number of investment opportunities we offer, and to create a new product for customers with a conservative risk profile.

Why do people want to work at your company?

We offer great investment products, of which the whole team is proud. The zinsbaustein.de culture is based on trust, an honest and open environment, professionalism, freedom, and fun.

What has been the most important milestone so far?

Private investors invested more than 30 million Euros through zinsbaustein.de. We are proud that all investments have been paid back in time or even earlier. This is also a proof of our quality focus.

Looking back at your whole development story — what makes you most proud?

That we kept the strict quality promise we made in the beginning. Some investments have been paid back with an 5,25% interest rate per year. We receive excellent feedback from our customers. They appreciate our transparency and the experience of our partners.

Where do you see your company in 5 years?

We will be the quality leader for digital real estate investments in Germany. There will be a lot of different opportunities to invest in real estate products, always trustworthy, honest and transparent. zinsbaustein.de will evolve to a quality stamp for real estate investments.

What is your impression of launching a startup from your based city?

Berlin offers good opportunities for connecting with other founders, specialists, and potential partners. All of us regularly visit events related to real estate, tech, and investment topics. These are good opportunities for personal growth that also drive our companies’ growth.

What is your impression of the german startup scene? Would you change anything?

Berlin has developed really well in the last years, but Germany still lacks a well-formed founder culture as well as sufficient venture capital. We need less administrative hurdles. We need a higher accessibility to growth capital. We need more social acceptance for the fact that most ventures fail.
