Vision and Mission


Empowering organisations to realise the full value of AWS cloud computing.


To be a trusted partner to our customers, helping them to be the best they can be, through innovative AWS cloud solutions.


Deep roots in energy, but ultimately we’re creative problem solvers

In 2016, D55’s co-founders met as part of a team solving complex B2B billing problems in the energy industry. The team had a perfect mix of technical talent, a growth mindset, minimal ego, and a collaborative and supportive dynamic. Above all, they built a reputation for getting stuff done. D55 was founded in 2018, quickly achieving AWS partnership in 2019 and adding dozens of highly skilled Cloud Architects, DevOps Engineers, Analysts and Testers. We’ve never looked back.

It’s fair to say we know a lot about B2B energy, and have worked on a wide range of engagements including incredibly detailed industrial pricing engines to complex systems integration between multiple COTS systems. We’ve found over time that the challenges and opportunities facing the energy industry also apply to many other sectors.

As an aside, a “D55” is a data bundle sent between energy suppliers in the UK when a consumer switches to a new provider. This is a nod to our energy heritage, and also to switching to something new and better when you engage with D55.

Solving problems with passion

Our Culture

Fundamentally, we love solving problems, and this simple premise is at the heart of everything we do. We excel in working with the latest AWS cloud-native technologies, but the real value our clients recognise comes from our collaborative, relationship-led approach to consultancy. Known for being pragmatic and transparent, we tackle problems at the earliest opportunity, solving them together. Our culture is as vital to our success as our technical prowess, with our passion evident throughout engagements.
