D55 enabled us to migrate from on-premise to a cloud-based solution, resulting in monthly cost savings of about 40%. Cloud-based systems give us a high level of resiliency and an unlimited capacity to scale. We’ve really put in place the foundations for later phases of work and further cost reduction as we scale. It was a partnership as opposed to a service - we work well together.
