Anyone who wants to take a sabbatical or go abroad on business is faced with the problem of what to do with their flat or to find one? The search for suitable subtenants is treacherous: - The supply and demand is scattered across X real estate platforms. - Sifting through and evaluating the applications is very time-consuming - There are many fake profiles on the platforms. I worked out the business model for solving the problems in subletting as part of my master's thesis. I have already been able to incorporate eID and eSignature into my platform. Furthermore, an included insurance, which covers 3 months of the rent, will follow. According to studies, the market is estimated at 1.9% of the rental market.
