About Us

Established in 2010, Atchai is a consultancy and development house based in London, UK. We work closely with customers to develop intelligent digital products, specialising in data science, machine learning, natural language processing, and conversational AI.

Our work is driven by new technology, user centred design and Agile methodologies. What makes us different is the team we work with; led by John Griffin and Dr. Enrique Munoz de Cote, all our people are experts in their field and have world-class credentials to back it up. 

We think creatively about technology and implement it strategically. We invest in new and interesting ideas and regularly release open source code to the community. Our recent clients include the Cabinet Office, Bank of England, UEFA, NHS Digital, Turner Broadcasting, Internews, and Mencap, along with a number of smaller organisations whom we love just as much.

What our clients say

We engaged Atchai to develop Nutricia’s first AI offering. We found Atchai’s experience and knowledge of this space invaluable.

Atchai’s approach to the project was very professional and well structured. I look forward to working with them again.

Matt Scott - Nutricia

Atchai helped us to design and build an innovative subscription payment system running on Ethereum.

Working with cutting edge technology in an emerging sector is a challenge. The team were fantastically agile, professional and reliable throughout the project, we communicated regularly and managed to develop a novel concept into working software within a short timeframe.

I highly recommend working with Atchai for any project that requires a creative approach backed up by strong engineering practices.

Bernhard Mueller - Consensys

John runs an agile, knowledgeable and experienced team of developers with a strong focus on enterprise, data-driven technical solutions. I have employed them for a recent, very challenging project mining the group associativity of social media networks.

I was highly impressed by the way John runs his team, the agile way in which they approach the work and even more pleased with their ideas and technical input. I would recommend John and his team at Atchai to anyone who needs a competent solution for any data-oriented enterprise project.

Adrian Leu - Inition

What I like about working with Atchai is that they take the time at the beginning of the project to understand the big picture before choosing the right tech stack for the job.

What they delivered was cutting edge, very high quality software.

All work was delivered on time, on budget, to a very high standard with clear, honest communication throughout.

Niels Bischoff - Mindbot

Atchai Digital created a highly innovative visualisation tool that successfully demonstrates the value of open health data on an imaginative open-source linked data platform.

This step-change innovation, which was profiled extensively at an international semantic web conference and a Guardian review, represents an important contribution to health informatics.

Atchai’s ability to work in development sprints that result in compelling customer experiences is a clear signature. In fact, the entire Atchai experience is enjoyable, pragmatic, and pleasantly surprising!

Matthew Wilkinson - NHS

Having put together a very well thought out and concise proposal we chose Atchai to deliver a new framework to power websites and digital products for our growing general entertainment business and brands.

John and his team came up with a technical approach which has proven to offer huge efficiencies in the production of TV channel support websites. We now have an underlying architecture which enables quick and efficient rollout of new websites, along with the tools to ensure that every site we produce is accessible across mobile devices.

Atchai were extremely professional, patient, and showed a great understanding of our often changing requirements and priorities. Their Agile approach to development, along with regular and effective communication allowed us to accommodate change and react quickly to evolving business and user requirements.

I’d highly recommend Atchai and wouldn’t hesitate to work with them again.

Olly Holmes
Turner Broadcasting

‘We were impressed with Atchai’s approach from the beginning interview.

John, Atchai’s principal consultant, was quick to understand our spec, the need of our clients and our ethos as a charity. It became apparent very quickly that John had extensive experience and skills, but at the same time John came across as being very down to earth and approachable.

This initial impression continued throughout our working relationship. John was easy to access by phone or email whenever there was ever anything that we didn’t understand or had to talk through. He managed our relationship with patience, thoughtfulness and efficiency, ensuring all the target deadlines were met as agreed.

We had a strong and effective working relationship with John in which he helped us to work creatively and to get the most out of our budget. From set up, through to delivery, launch and closure, John was reliable, professional, thoughtful and inspiring.

We highly, highly recommend Atchai.

Jo Giles

The Atchai team have been invaluable in helping us to understand the limitations, implement best practice and realise the full potential of recent digital projects. John in particular is an extremely knowledgable consultant, with unparalleled Drupal expertise and a pragmatic approach to development. The team is efficient, reliable and get things done. A pleasure to work with.

James Guest
Open Communication

John’s skill lies in being able to very quickly understand requirements and come up with a creative solution to the problem that draws on the very latest knowledge and techniques.

His obvious experience in not only delivering top notch technical solutions but also in gathering requirements in a very user focussed way has given everyone the confidence that we now have a great solution to our problem – not only conceptually but also coded and ready to implement.

In addition his clarity and genuine approachability for both technical and non-technical staff makes him a fantastic asset to a project.
