There are three ways to build supply: find more providers, create some of the supply yourself, or bring in the existing supply from other sources.
To attract more suppliers to your platform, highlight the value of your marketplace, show your buyer potential, and offer incentives. You can also pay for the initial supply.
To increase the number of listings, reach out to your existing suppliers and support them in creating and optimizing their listings. Reward them for their loyalty, too – for example, by providing exposure for their brand on your social media pages.
