Über das Unternehmen

FinLink is a next generation mortgage platform making home ownership simple, transparent and accessible for everyone. 

In our mission to make home ownership simple, transparent and accessible for everyone, FinLink has helped more than 100.000 people finance their home. 

We are a b2b2c software company striving to give home buyers and mortgage advisors a fully digital mortgage experience. 

We connect the home buyer’s journey of buying property with value-adding services along the way such as property valuation, robo-advice for financing options and leveraging AI to classify and read documents.

Our advisor-facing application includes a fully-fledged back-office that empowers the advisor to support the customers with a maximum service level: We offer a reliable and efficient mortgage application processing using workflow management, e-mail, chat, as well as secure handling of financial documents - just to name a few.

Our vision is to connect all areas of the real estate ecosystem to be a central hub for every stakeholder in the market. Our partners include real estate platforms (e.g. Immoscout24 and Immowelt), property valuation companies and lenders.

Over 600 mortgage advisors from 100+ different companies use FinLink, including Swisslife Select, Baufi24, Homeday and Immo-finanzcheck. 

FinLink is part of the Baufi24 group, Germany’s fastest growing mortgage broker with 60+ branches across Germany.
