FOUNDER(S) | Veronica Cabezas, Ricardo Cuervo

This fashion startup aims to take on the product recommendation problem by applying machine learning to the shopping process.

Customers using the platform receive a style code that indicates the degree to which they skew away or toward the expected/wanted style.

In the process, fashion retailers can read the data and target them with personalized offers.

Genostyle can also examine the retailer’s inventory and what sells best and how the client can optimize its stock.
