Keepa

Leading Amazon price tracking and product research tool

Keepa is a comprehensive Amazon price tracking and product research platform that has become an essential tool for Amazon sellers, buyers, and researchers. The service tracks historical price data, sales rank, availability, and other metrics for products across all major Amazon marketplaces. Founded in 2011, Keepa has grown to track millions of products and provides both free browser extensions and premium subscription services. While not a traditional AdTech company, Keepa operates in the e-commerce intelligence and marketplace analytics space, providing data that enables sellers to make informed decisions about pricing, product selection, and market opportunities. The platform offers browser extensions for Chrome, Firefox, Edge, and Opera, as well as a comprehensive API for developers and businesses. Keepa's extensive historical data and real-time tracking capabilities have made it one of the most popular tools in the Amazon seller ecosystem. Keepa generates revenue through premium subscriptions that unlock advanced features like detailed sales rank history, extended data retention, and API access. The company maintains a relatively low profile but has established itself as a critical infrastructure tool for Amazon marketplace participants, from individual resellers to large e-commerce businesses and research firms.
