e.fundamentals develops an eCommerce analytics platform, built on GCP, that allows a growing number of world class manufacturers to increase their sales across all online channels.

Their revenue has grown by more than 300% in the last 12 months as world-leading companies such as PepsiCo, Mars, Kellogg’s, HP, and Starbucks have adopted their Digital Shelf Analytics platform. Their platform turns billions of data points, for millions of products being sold online, into actionable insights that generate an average 10x ROI for our customers.

The Data Products squads mission is to store the millions of product records gathered by the client platform every day and make this data available to clients, either through an open-sourced data API or automated scorecard generation. They also use the data to create new products or features that can enrich the client service. These involve things like linear regression of sales data to calculate market share or improving our daily operations and data quality system by identifying and flagging possible errors in the data input stream.
