A marketplace brings you to the heart of the ecosystem so you can have data and good market visibility. For example, a logistics company that transports products from one company to another can aggregate all these various actors to allow them to trade online while continuing to carry out their initial logistics business. Instead of being just a link in the chain, you take control.
By placing yourself at the heart of the ecosystem, you can bring together all the suppliers that are part of your industry's value chain. The user has a single space in which to concentrate all their purchases.
In addition to your traditional business, a marketplace allows you to diversify by aggregating partner suppliers' offers. You increase your value proposition and your turnover.
