The timeline below provides more information if you're interested in our history.

Mark Zaretti MSc

I've been building online websites and database systems since the late 90's. My background was scientific (BSc, MSc), and when I graduated, the University of Manchester created a startup company (Sagittus Solutions) selling the bioinformatics software systems and databases I developed to clients internationally. During my time there I helped train bioinforaticians on the Masters program and appeared in Nature magazine. After several years I was head hunted by Pfizer (Global Research and Development) to develop a number of key global research software systems. 5 years later, with a number of software patents to my name, several corporate achievement awards and a legacy of over 50 IT projects in production I decided it was time to take my skills to SMEs and individuals, and ZARETTI Consulting (then called Sparticle) was created.
I'm a creative problem solver, a communicator, and an educator. Put these together with the skills developed during my productive "corporate years" and it means I'm experienced and able to help real people get great IT and creative media services.

A Background in Multimedia

So how does a scientist/geek also end up running a media company? I've always been a photographer and in 2002 with a number of public photography exhibitions, and several commissions working the London music scene I started working as a freelance digital photographer. Once the web consultancy business was running it became clear that there was genuine overlap between the digital media and web technology worlds. Great websites need great photos and online videos. In 2007 I created Spartmedia Ltd to deliver filming and editing of online promotional movies.
