Adknowledge
Adknowledge is an ad network which provides an online pay-per-click marketplace for high quality traffic across multiple channels of email, web and search engine inventory.

BackType
BackType is a real-time, conversational search engine. We index and connect millions of conversations from blogs, social networks and other social media so you can find out what people are saying about the topics that interest you.
Read about how BackType uses Cascading on their tech blog. BackType engineers are the authors of Cascading-DBMigrate and Cascalog.
Bixolabs
Bixolabs is an elastic web mining platform that makes it easy to create web mining apps, so customers can focus on what they know best - using the data - without the challenges of building out a reliable, scalable web crawling and data processing workflow.
Bixolabs is built on top of Hadoop, Cascading & Bixo, and runs in EC2. This makes it a flexible, scalable, on-demand solution for companies processing web data for internal use, as well as companies building products based on web mining.
Delve Networks
Delve provides a complete online video solution to manage, publish, measure, and monetize high quality video content on the web. We power video for well known sites in the media, sports, health, finance and other verticals.
At Delve we use Cascading in conjunction with AWS services such as EC2, S3 and Elastic MapReduce to scale video analytics for our rapidly growing collection of usage data. We are planning on leveraging it further to build additional business intelligence applications.
Etsy
Etsy's mission is to enable people to make a living making things, and to reconnect makers with buyers.
Read about how Etsy leverages Cascading on their blog in Analyzing Etsy's data with Hadoop and Cascading. The Etsy engineers also maintain the Cascading.JRuby DSL.
Feeva
Feeva has created a digital bridge between fixed and mobile service providers and the digital marketing industry. This bridge solution enhances the performance of digital marketing campaigns while maintaining the highest standards of consumer privacy.
Feeva uses Hadoop, HBase and Cascading for two areas right now.

FlightCaster
FlightCaster predicts flight delays. We use an advanced algorithm that scours data on every domestic flight for the past 10-years and matches it to real-time conditions.
Read about how FlightCaster predicts flight delays with Cascading on InfoQ, DataWrangling, SDTimes, and InformationWeek. Or listen to an interview on Cloud Cafe. FlightCaster engineers created and contribute to Cascading-Clojure.
Nextag
Nextag is a comparison shopping website that helps consumers make informed decisions about what and where to buy products they'll love.
Nextag uses Cascading to aggregate and analyze billions of user actions in order to improve and help scale search relevance, recommendations and reporting.
