Redis
Redis is the company behind the world's most popular in-memory data store, the open-source database that began as a side project by Salvatore Sanfilippo in 2009 and now sits in the stack of most of the internet's largest applications. It sells managed and self-hosted enterprise versions - Redis Cloud and Redis Software - layered on the open-source core, and has pushed hard into real-time AI use cases like vector search and LLM memory. After a turbulent 2024 licensing fight that spawned the AWS-backed Valkey fork, Redis returned to an open-source license (AGPLv3) with Redis 8 in 2025.
Rowan Trollope
Rowan Trollope is the CEO of Redis, the ubiquitous in-memory data platform powering real-time applications worldwide. A self-taught programmer who started coding on a Commodore 64 at age 11, he brings over 30 years of technology leadership across consumer products, cybersecurity, infrastructure, and collaboration software. Before Redis, he quadrupled revenue at Five9 and spent years at Cisco reinventing its collaboration business. At Redis, he has repositioned the company from a beloved developer caching tool into a critical AI infrastructure layer, launching semantic caching (LangCache), acquiring real-time data platform Decodable, and steering a controversial but successful licensing pivot that he says has produced record growth.
