Is your data leaking?
It could be sinking your business

Traditional databases are designed to lose data. EventStoreDB captures and retains all your data at an atomic level, in sequence from anywhere inside your organization, and works seamlessly with any downstream system in real time.  EventStoreDB is the real source of truth built for today’s fast-moving event-driven systems.

Who's using Event Store?

EventStoreDB has quite a few benefits... because it's designed to have an immutable series of events in streams. It makes natural sense, the way it's designed... it has lots of performance benefits.

What is an Event Database?

Event Databases store data as events. They don’t overwrite your data, so no data is ever lost. Each event is stored in a stream that can be read or queried as needed. You can move up and down the stream of events, giving you new insights and the power to make better, more informed decisions that you can trust.

 When older systems need replacing, do it at your pace. Needs long term planning, down time and to happen all at once.

Why use EventStoreDB?

Businesses today are driven by digital events happening in real time. An event in one area of the business triggers a response in an app that runs another. These apps and services must respond constantly, without delay or data loss. Scale is mission-critical because there are thousands or even millions of events occurring every minute of every day. Without a single, foundational database of these events, today’s apps and services can’t work. Failure is inevitable. EventStoreDB is the only native event database that provides the record of events to support these new apps and services.
