Case Study: Brex achieves faster, lower-cost developer testing with Signadot

Brex cuts preview environment costs 99% with Signadot

Brex, a finance platform for startups and enterprises, faced significant challenges with its Kubernetes-based preview environments. As the company grew to over 800 microservices, the cost and complexity of duplicating entire namespaces for developer testing became unsustainable, leading to unreliable environments and a high infrastructure bill. To address this, Brex turned to vendor Signadot and its platform for creating isolated sandboxes.

Signadot's solution allowed Brex to create lightweight, ephemeral environments that isolated only the specific services being changed, while routing traffic to stable versions for all other dependencies. This approach drastically reduced infrastructure costs by 99%, saving an estimated $2 million annually. It also slashed the time to create a service preview from 30-60 minutes to under 5 minutes, significantly improving developer satisfaction and velocity.
