I am not a finance or business expert but it is stated in the Quran that there is a clear distinction between "business" and "usury", where the former is encouraged but the latter is prohibited.

The implementation of it is opened for the interpretation of the experts based on the basis of this particular distinction.

Fun fact, Muhammad was a very successful businessman and has been doing international trading to Sham (modern Syria) since he was a very young boy. He managed to retire from business before he is 40 years old and it is due to his business success not because that he is married to his first wife Khadijah. Basically he is a business startup founder with Khadijah as one of his main VC partners.
