Company Overview

Redis (Remote Dictionary Server) was initially created by Italian developer Salvatore Sanfilippo (antirez) in 2009. Redis Labs (later renamed Redis Ltd.) was founded in 2011, headquartered in Mountain View, California. Redis is the world's most popular in-memory database and caching system, often called a "data structure server," with a valuation exceeding $2 billion. Redis is known for its extreme in-memory performance and rich data structure support (strings, hashes, lists, sets, sorted sets, bitmaps, HyperLogLog, geospatial indexes, streams, etc.), making it an indispensable infrastructure component in modern application architectures.
