a little about our company...


We are a small family team. Our developer has worked in schools for over thirty years as a maths teacher, timetabler, assessment manager and computer programmer. Our support and training person worked for many years in an international financial software company. She gave this up so that we could offer one-to-one support to our customers (and our daughter!)

Paul has been working in education for 35 years, first as a maths teacher, later as a consultant for curriculum, timetabling, assessment tracking and Sims Nova-T6. He has been programming since the 1970's and has written many applications, general and bespoke, to solve organisational problems within schools. Paul has trained many first-time timetablers but his special skill lies in the fact that he knows how to make a school timetable of the highest quality for both students and staff.

Catherine is English/Spanish bi-lingual and began her career in the city working for an international banking software company. She now offers support for our applications and offers administrational help to junior schools. She has experience with the setting up and running of third party school library system software. Catherine is also a professional Jazz musician who performs at various venues in and around London.
