What our Clients Say

“While we led the initial business scoping and discussions with key stakeholders, it was a very smooth process working the D55 team to expand on this vision. The D55 team took ownership of building the solution and worked closely with us throughout the process. The quality of the work, combined with the excellent support during the handover, is exactly what we value in a partner.”

Amber

" 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. "
