Redis
Redis is an In-Memory & Caching company founded in 2011 and based in San Francisco, United States. It has raised $347M in total funding, most recently a Series G in 2021 at a $2B valuation.
Redis was founded in 2011 as Garantia Data by Israeli serial entrepreneurs Ofer Bengal and Yiftach Shoolman, renamed Redis Labs in 2014 and simply Redis in 2021 as it became the commercial steward of the in-memory key-value store Salvatore Sanfilippo created in 2009. The company monetizes through Redis Cloud and self-managed Redis Software, and has raised $347M, last valued above $2B in its April 2021 Tiger Global-led Series G. Former Five9 chief Rowan Trollope took over as CEO from Bengal in February 2023 and steered the company through its defining controversy: the March 2024 switch from BSD to source-available licensing, which triggered the AWS- and Google-backed Valkey fork — then a reversal that brought Sanfilippo back as developer evangelist in late 2024 and returned Redis 8 to genuine open source under AGPLv3 in May 2025. Trollope has repositioned Redis as the real-time data and memory layer for AI, adding vector sets, the LangCache semantic-caching service, and acquisitions of Speedb (2024), Decodable, and Featureform (2025). Redis counts more than 10,000 customers and remains one of the most widely deployed databases in the world.
Redis is the caching backbone of the modern internet now racing to become the memory layer for AI agents — its vector search and LangCache semantic caching cut LLM latency and token costs — while its BSD-to-SSPL-to-AGPL licensing saga made it the defining case study in open-source monetization and the fork risk (Valkey) that comes with it.
