Meet the people behind DeltaXML

At DeltaXML we enjoy developing simple solutions to difficult problems.


We are completely focused on managing change to structured information. Our comparison and merge software tools transform the way our customers handle change in their XML documents, XML data and JSON files.

We have been working on this for almost as long as XML has existed and our first product was formally launched in 2001. Since then, tens of thousands of people in hundreds of companies have benefited from using our products. Although XML is in our name and was our initial focus, JSON is a natural step for us as a popular format for structured data.

The Management Team


Founder and CEO – Robin La Fontaine

Robin is the founder and CEO of DeltaXML. He holds an Engineering Science degree from Oxford University and an MSc in Computer Science. His background includes computer aided design software and much of the DeltaXML technology originates from this area – the management of change in electronic circuits is a complex problem where accuracy is critical. He has grown DeltaXML from very small beginnings to a leading position with major corporate and public sector customers. On the basis that we do not often get things right first time, his view is that efficient identification and management of change can give a significant competitive advantage.

Global Business Development – Phill Barratt

One of the newest members of the DeltaXML team, Phill is commonly described as a professional and enthusiastic individual, with a fountain of knowledge surrounding XML products as a consequence of over twenty-five years in the XML industry. Phill’s career began as a postgraduate in social sciences, psychology and social work, and following his degree he secured a position as an XML sales engineer where he developed his understanding of the XML industry. Embracing his skills and knowledge in XML, Phill saw himself in a variety of high level sales and marketing roles within the XML industry which has provided him with a unique perspective and understanding of the industry which he is now uses to support DeltaXML.

Tristan Mitchell

Product Manager – Tristan Mitchell

One could argue that playing ‘Arcadians’ on the Acorn Electron back in the 1980s was the real beginning of Tristan’s computing career. Tristan’s official education and passion for computing came in the computer science classes he took at high school, leading him to the University of Wales, Aberystwyth to complete an MEng in Software Engineering. Tristan has been working with DeltaXML for over ten years, and in that time has contributed much, driving DeltaXML to its place as a market leader in the XML document and data comparison industry.

Chief Software Architect – Nigel Whitaker

Nigel has put his software engineering background to good use over the past twelve years in taking the DeltaXML software from a small command-line utility to a very efficient XML comparison engine and toolkit, the tool of choice for many leading companies. Nigel ensures that our code is well-written, documented and tested, and that our APIs and interfaces are useful to our customers. He previously had a post-graduate research post at the University of Manchester.

Our Values

We understand that people rely on our software and that it performs a critical role in many organisations,
from government and finance to aerospace and research. We believe we have a serious responsibility to live up to their
expectations, delivering ever better and always high quality software and support.

We have been accredited with ISO 9001 and ISO 27001.

ISO 9001 is the world’s most recognised management standard. It is based on a number of quality management principles including a strong customer focus, the motivation and implication of top management, the process approach and continual improvement.

ISO 27001 was awarded to us due to the proof that DeltaXML prioritises data security. Customer data is rigorously protected and we strive everyday to assess, minimise and eliminate any and all risks and vulnerabilities.
