We're building a platform for alternative, bottom-up, high-granularity econometric data capture, particularly targeting opaque developing economies (i.e., Argentina might lie about their inflation statistics, but their black market certainly doesn't). Basically we get to funnel hedge fund money into improving global economic transparency.
We've been using Storm in production since January 2012 as a streaming, time-indexed web crawl + extraction + machine learning-based semantic markup flow (about 60 physical nodes comparable to m1.large; generating a modest 25GB/hr incremental). We wanted to have an end-to-end push-based system where new inputs get percolated through the topology in realtime and appear on the website, with no batch jobs required in between steps. Storm has been really integral to realizing this goal.
About Wego, we are one of the world’s most comprehensive travel metasearch engines, operating in 42 markets worldwide and used by millions of travelers to save time, pay less and travel more. We compare and display real-time flights, hotel pricing and availability from hundreds of leading travel sites from all around the world on one simple screen.
At the heart of our products, Storm helps us to stream real-time meta-search data from our partners to end-users. Since data comes from many sources and with different timing, Storm topology concept naturally solves concurrency issues while helping us to continuously merge, slice and clean all the data. Additionally with a few tricks and tools provided in Storm we can easily apply incremental update to improve the flow our data (1-5GB/minute).
With its simplicity, scalability, and flexibility, Storm does not only improve our current products but more importantly changes the way we work with data. Instead of keeping data static and crunching it once a while, we constantly move data all around, making use of different technologies, evaluating new ideas and building new products. We stream critical data to memory for fast access while continuously crunching and directing huge amount of data into various engines so that we can evaluate and make use of data instantly. Previously, this kind of system requires to setup and maintain quite a few things but with Storm all we need is half day of coding and a few seconds to deploy. In this sense we never think Storm is to serve our products but rather to evolve our products.
At Rocket Fuel (an ad network) we are building a real time platform on top of Storm which imitates the time critical workflows of existing Hadoop based ETL pipeline. This platform tracks impressions, clicks, conversions, bid requests etc. in real time. We are using Kafka as message queue.

Akazoo is a platform providing music streaming services. Storm is the backbone of all our real-time analytical processing. We use it for tracking and analyzing application events and for various other stuff, including recommendations and parallel task execution.
At Mapillary we use storm for a wide variety of tasks. Having a system which is 100% based on kafka input storm and trident makes reasoning about our data a breeze.
We recently upgraded our existing IT infrastructure, using Storm as one of our main tools. Each day we collect sales, clicks, visits and various ecommerce metrics from various different systems (webpages, affiliate reportings, networks, tracking-scripts etc). We process this continually generated data using Storm before entering it into the backend systems for further use.
Using Storm we were able to decouple our heterogeneous frontend-systems from our backends and take load off the data warehouse applications by inputting pre-processed data. This way we can easy collect and process all data and then do realtime OLAP queries using our propietary data warehouse technology.
We are mostly impressed by the high speed, low maintenance approach Storm has provided us with. Also being able to easily scale up the system using more machines is a big plus. Since we're a small team it allows us to focus more on our core business instead of the underlying technology. You could say it has taken our hearts by storm!
We are using Storm to track internet threats from varied sources around the web. It is always fast and reliable.
