Why EventStoreDB?

Are you facing downstream complexity, losing critical data, and not storing the business context?

Traditional database technologies can no longer support the real-time demands of modern-day financial systems. EventStoreDB allows you to store not just the data but the context of that data which is critical to auditing and compliance. 

That’s why many FinTechs and financial companies have opted for EventStoreDB, a database built for Event Sourcing that maintains the fast distribution of information, reduces downstream complexity and keeps an audit trail of who did what and when - helping you to meet the increased regulations.
