Every cart is
half a story.
Sales Advancer is a recommender system we train on your shop’s own sales. At every checkout it suggests what this customer is likely to add.

The grocer knew. The aisle forgot.
Three hundred years ago the shopkeeper knew your usual order and had the next thing ready. In 1916 Piggly Wiggly opened the first self-service grocery, and shoppers started finding everything on their own. Most online shops still work that way.


Sales Advancer gives an online shop that memory back, for every customer at once.
It learns from past orders.
At every purchase we recommend extra items that fit the customer. The model looks at what each person bought before and learns which products suit them.
