Tony Butcher

Managing Director

I studied B.Sc. Engineering Science at Durham University, obtaining a First in 1986. I later obtained an M.Sc. from London University in Organisational Behaviour.

During my early career I worked in at Schindler Lifts, Accenture, Motorola and London Underground, in software development, consultancy and project management. I started Tribal Internet as a company in 1996, just as the internet was starting to gain a broad appeal. We rebranded under the Zenario trademark in 2008 as we were gaining more international reputation for our services and our CMS software.

I have always been interested in databases and have written two books on MySQL, the world's most popular open source database.

I'm still the owner of Zenario and my energy is undiminished; I'm looking forward to more projects in which we can deliver our great service and build long-lasting customer relationships.


Glenn Jenner

Creative Director

I gained a distinction level at HND Computer Graphics at Worcester College in 1998, following that I studied Graphic Communication at The University of Wales Cardiff, receiving a First at B.A in 1999.

Prior to my design career I worked in Print and Publishing, operating Litho presses, I ran the Reprographic department of Devon County Council for five years, and A&S Publishing in Gloucester working on a selection of car magazines.

My first design job was with a Reading based design agency, working on websites, multimedia and direct marketing campaigns. I joined Tribal Systems in 2004, where I work very closely with both clients and our development team to deliver form, functionality, quality and richness of design in our websites. I always challenge myself to keep my design skills fresh and innovative, and I apply this to my work on both websites, interface design and information architecture.

When I am not creating websites, I love illustrating, using both pens, paper and on the Mac, I am inspired by the work of people such as Vaughan Oliver, Gerald Scarfe and Jon Burgerman. I also keep tropical fish and am the proud owner of two Clown Loaches named Krusty and Ken.


Chris Turnbull

Senior CMS Developer

I obtained a BA in Computer Science from Cambridge University in 2004 and spent the next three years in a company developing web-based applications. Shortly after I received my MA, I joined Tribal Systems in 2008.

I focus on inventing new tools and systems to put into the CMS (Zenario content management system), and on refining and maintaining the existing functionality. My intention is to keep adding features and improving the ease of use of the CMS, rather than let it stay static.

I also oversee the module API and TUIX, which let developers create new plugins and add new features to the CMS.

In my spare time I like to make my own websites, read manga and play roleplaying games. I am one of those people who own both a PC and a Mac.


Matthew Holtom

Project Manager

After achieving A-levels in Computing, Physics and Maths, I spent a year working in Australia where I calibrated and repaired electrical test equipment. On returning to the UK I worked as an electronics/software engineer at a company based in Newbury, looking after the company's database portal that was coded in "Coldfusion". I went on to study computer software and programming with Java, at the Open University.

I joined Tribal Systems in 2013 where I create bespoke Zenario modules that meet unique requirements for customers using our content management system. I ensure the module developments provide cost effective solutions for you.

Outside of work I enjoy keeping fit and active, I play badminton for my local club and football for a local pub team. I'm also a keen snowboarder.


Robin Livesey


I attained A-levels in Mathematics, Further Mathematics, Computing, and Physics at AS level. Whilst studying I learnt Pascal and in my free time Python, MySQL and HTML.

Having always had a great interest in technology and programming I joined an Apprentice scheme to gain a more hands on experience. I joined Tribal Systems in 2013 through the scheme and have enjoyed gaining experience and knowledge as a Web Developer.

At Tribal I work on creating and maintaining modules on the Zenario content management system. I have built skills with PHP, Javascript and C#.

Outside of work I am a fan of badminton, table tennis and video games.


Liz Franco

Web Designer

I attained a B.Sc. in Computer Engineering in 2003 at UNAB (Colombia). Early in my career I had a great interest in the Web and front-end design and development work. I learned PHP and loved the power of this scripting language. I did my traineeship in Stuttrgart, Germany working mainly with Visual Basic.

By 2004 I was the co-founder and developer of a website development company in Colombia, where I live. I joined Tribal Systems in 2005 and since then I'm really pleased to be part of this talented team of people. My native Spanish helps Tribal Systems offer our software and services in the American markets and the 6-hour time zone difference means we offer extended hours of support to European customers.

I enjoy creative and challenging design projects that push me to learn more about web design, and supporting customers with their needs.

I enjoy reading about the internet, learning new things, cooking, 70's & 90's music and trying new restaurants in my home town.


Jackson Diaz

Junior Web Developer

I studied DipHe IT System Administrator and DipHe Software Development at Cesar Manrique Collage and then BA in Computer Science at University of La laguna in Tenerife Island, Spain. I had the opportunity to learn many programming languages which allowed me to delve into the object-oriented programming and develop applications in different work environments.

I started my career as a System Administrator in the Town Hall of La laguna in Tenerife, where I could implement my knowledge of networking and servers. Later I worked in several software development companies where I focused primarily on web development using PHP and Mysql.

I joined Tribal Systems in 2014 as Junior Web Developer / System Administrator where I develop modules for Zenario content management system, and I'm very proud to be part of this company and work with talented people. Outside work I enjoy learning new things about technology, discovering new places, travelling and playing Ten-pin Bowling.
