Our story

EventStoreDB was first developed back in 2011 by Greg Young, a pioneer of CQRS and Event Sourcing. This was done in a joint effort with BathASU, a pharmaceutical compounding company based in Bath, UK. At the time BathASU had a strong business case for adopting Event Sourcing and hired Greg to help them build a new system. Rather than build “yet another event store”, as Greg had done on many previous occasions, an open-source project was started and the resulting Event Store database was made available in 2012.

Due to demand, Event Store began offering a commercial support option and slowly grew a strong customer base of organizations such as Walmart/Jet.com, Xero Accounting Systems, UK NHS (National Health Service), checkout.com, and CERN. Since that time, EventStoreDB has been deployed in thousands of production clusters, running mission-critical, high value, web-scale workloads around the world.
