Meet the team


Tim Simon, CEO
Tim has been described as a “serial entrepreneur”, having founded three software firms servicing the financial sector. In 1975, he founded his first company and in 1981 he floated it on the LSE as Quotient plc. By the time he sold the company 10 years later for £27.2m to ACT Group, Quotient plc had 8 international offices and over 500 institutions as clients, many of them the world’s largest banks and securities houses. Some of its market leading products are still used today as the core part of financial institutions’ business systems. He floated his second business, Mondas (now Corero), on the Alternative Investment Market (AIM) in 1996. Madiston is his third company, with arguably the greatest potential. Tim combines his skills in management with designing, building and marketing software applications and his passion for financial sector markets.

With a background in marketing, finance and administration, Sally worked with many IT and small business as a consultant. She joined Tim at his second business, Mondas, when it was a sole trader business, becoming Company Secretary and responsible for marketing.

She has taken products from launch to market leading positions, established quality procedures and helped small businesses grow.
