About Us

The founders and directors of XL Numerics are Harold Graycar and Ted Sandeman. We are in the business of helping our clients gain strategic insights from their corporate data.

Our backgrounds are in the numerate sciences, and after experience in a number of large corporations and public sector organisations, we came to the realisation that many mid-level and senior executives need assistance in understanding, analysing and communicating the numbers that drive their businesses.



Having worked as technical staff and managers, and then with management consultancies including Price Waterhouse, Deloittes and IBM, we found a recurring theme: while most executives have a firm grasp on the day-to-day activities of their business, they are not always confident in:

  • Analysing data
  • Looking for and understanding trends
  • Making objective, data-based decisions
  •    and most of all …
  • Presenting numerical information to their peers and business stakeholders.
XL Numerics was formed to address this gap, and we do so by working with clients either individually or in teams to develop their skills in analysing and presenting corporate data.

Since 2003, we have developed and delivered courses on how to increase business productivity and extract value from corporate data to hundreds of business executives, analysts and planners. In 2008, we began presenting our courses throughout South East Asia.

Our clients span a number of industries, and we have worked with organisations involved in: telecommunications, utilities, transportation and logistics, product distribution, retail, customer service centres, financial services and public sector management.
