Smarter Data, Stronger Decisions

Most organisations already have the data, but it’s siloed, inconsistent, or hard to access. Our AWS-powered data services create a single source of truth so every department works from the same reliable information.
‍
That’s how you achieve faster decisions, smarter strategies, and measurable results.

80% of enterprise time is spent preparing data rather than analysing it

Frequently Asked Question

1. How can I get started with D55?

Start with a free Data Strategy Diagnostic — an AWS-backed assessment that benchmarks your maturity, identifies gaps, and provides a clear roadmap for your data journey.

2. What makes D55 different from other data consultancies?

D55 combines deep AWS expertise with a business-first mindset — meaning we don’t just build data platforms, we build solutions that directly impact performance, cost, and decision-making.

3. Do I need to already be on AWS to work with D55?

No. Whether you’re on-prem, multi-cloud, or starting your migration, we can assess your current setup and create a roadmap to AWS that fits your goals and budget.

Most projects start with an assessment phase (2–4 weeks), followed by implementation in stages — typically delivering measurable results within 8–12 weeks.

5. What industries does D55 specialise in?

We work across energy, pharma, SaaS, retail, and financial services — industries where secure, real-time data is critical to growth and compliance.

6. Can D55 help with data compliance and governance?

We follow a multi-layered approach. Our code adheres to OWASP Top 10 standards. On the infrastructure side, we use AWS Config for compliance monitoring, IAM for strict access control, and ensure all data is encrypted at rest and in transit. We design architectures that comply with GDPR, PCI DSS, and ISO requirements.

7.What kind of AWS services do you use for data projects?

Our solutions leverage AWS services like Aurora, Redshift, Glue, S3, Lambda, and SageMaker to deliver scalability, automation, and AI readiness.

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.”

CTO

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. "
