The rise of rapid delivery has transformed the way people shop for groceries and convenience goods, with apps like Uber Eats, Flink, and DoorDash delivering products in under two hours. However, consumer packaged goods brands have struggled to keep up, lacking visibility into stock levels, search rankings, pricing, promotions, and other key metrics. Rapid Delivery Analytics (RDA) is a Paris-based startup that offers a digital shelf analytics platform built specifically for rapid delivery, providing real-time visibility into these critical areas across over 40 delivery apps in more than 100 countries. RDA's platform uses ClickHouse Cloud on AWS to power its analytics engine, which ingests and processes billions of rows of data daily, enabling fast query performance and scalability. With the help of ClickHouse Cloud, RDA has achieved cost savings, improved efficiency, and the ability to scale without sacrificing performance, allowing it to support large CPG brands like PepsiCo and Unilever in a rapidly evolving market.
