Hey, we at Volument (volument.com) are using Redis as the primary datastore. We are extremely happy we chose that option. It gives us everything we need: extreme performance, scalability with customized sharding, stability with sentinels, and most importantly: a fantastic data model that is enjoyable to work with. We don't need to add anything extra to our stack if we later need a pub/sub system or realtime support for our custom chat app for example.

We use a custom Go-based system to collect the crazy amount of analytics that easily exceeds our memory, but for the core business logic, Redis is a top-notch choice. We actually build our whole CRM on top of Redis: https://volument.com/blog/the-power-of-simple-crud
