Kurrent

Kurrent, formerly known as Event Store Ltd, operates at the intersection of operational databases and real-time data streaming, providing an event-native data platform. The company was founded in 2011, with the open-source EventStoreDB being released in 2012 by Greg Young and his team. Young is a well-known figure in the software community, credited with coining the term “CQRS” (Command Query Responsibility Segregation), a pattern closely related to event sourcing.

The firm's core offering, KurrentDB (formerly EventStoreDB), is a database specifically designed for event sourcing. Instead of storing the current state of data, it records every change as an immutable event in a time-ordered sequence, creating a verifiable audit trail. This approach allows for the reconstruction of an application's state at any point in time by replaying these events. The platform is engineered to address the complexities that arise from separating state-based data models, like those in traditional SQL databases, and event-driven streaming systems such as Apache Kafka. By unifying database storage with real-time streaming capabilities, Kurrent provides developers with fresh, streaming data enriched with historical context.

Kurrent generates revenue through commercial support plans, consulting services, and training for its open-source product. It also offers Kurrent Enterprise Edition, which includes features like enterprise connectors for Kafka, MongoDB, and RabbitMQ, enhanced security, and automated management capabilities. Additionally, the company provides Kurrent Cloud, a fully managed multi-cloud database-as-a-service (DBaaS) available on AWS, Microsoft Azure, and Google Cloud Platform. The platform serves a diverse global client base across sectors like finance, healthcare, retail, government, and manufacturing, with notable customers including Walmart and Xero.

In late 2024, the company rebranded from Event Store to Kurrent to better reflect its mission of making data flow like a current, with full context. Concurrent with the rebranding, Kurrent announced a $12 million funding round led by Crane Venture Partners with participation from Creandum, aimed at accelerating engineering and go-to-market efforts. The company's leadership includes CEO Kirk Dunn and VP of Engineering David Wang, both veterans of Cloudera, who were appointed in October 2024 to scale the company's enterprise business.
