RTX21 stands for the real estate token exchange of the 21st century and is a Proptech that offers (institutional and later also retail) investors the opportunity to invest into fractional commercial real estate ownership on a single-asset basis. Real estate from 10m EUR entity value upwards is available on the platform for investment and will be connected to a regulated security token exchange to offer investors an opportunity to fungibly trade real estate security tokens on the secondary market. The founders unite multiple decades of experience in the corporate finance as well as real estate realms and aim at building a one-stop shop for the real estate industry, not only including a up-to-date digital dataroom per asset on platform, but offering the opportunity for third party service providers, such as banks, insurances and asset managers, to pitch their services per asset directly on platform.
