Pros of selling on a Marketplace


It may seem that Marketplace reduces your profit by commission and restricts your freedom by various conditions. However, in return, our Marketplace helps to promote your company and products:

  • We draw attention to your products and brand with special labels.
  • You can become a top-ranking developer and gain customers' trust. 
  • Our Marketplace has all the necessary target audience.
  • The Marketplace provides you with advertising opportunities, as well as various options for discounts and special offers.


Partnership with the Marketplace will have a positive effect on your sales: 

  • Higher conversion — every extra click lowers the conversion and the purchase probability.
  • Security — the Marketplace has its own licensing system and upgrade server.
  • Convenience — the Marketplace provides an API for integration with your own services.


We all know how difficult it is to get new customers and work with the audience. In order to help you with this, we provide the following features:

  • A newsletter for potential clients. Inform your clients about your products and their perks, current promotions and special offers, share news and promo codes.
  • A newsletter for your customers. Offer your current customers products that might also be useful. 
  • A customer base. Collect and store all the necessary data for audience analysis.
