Stream

Stream provides APIs for building activity feeds and chat. We've just raised a $15 million Series A round and are one of the fastest growing startups in Europe. As a developer at Stream, you will build software that’s used by tens of thousands of developers and more than half a billion end-users. Stream’s APIs are powered by Go, RocksDB, and Raft - with response times typically measured in single-digit milliseconds. The React Chat tutorial is a nice way to learn more about our product.
