Warwick Meier is a multidisciplined forensic specialist with deep skills in accounting, investigations and data analytics. His primary focus is forensic data analysis, with a career spanning both the South African public and private sectors.

"I have successfully managed, investigated and analysed people, companies and complex schemes — and the results of my work have been successfully used in court proceedings and disciplinary hearings."

His career began at PricewaterhouseCoopers in 1995, working in the Public Sector Consulting Division. He subsequently joined the Auditor General's Special Investigations Component in 2001, before being appointed as a Chief Forensic Investigator at the Special Investigating Unit (SIU) in 2003.

At the SIU, Warwick rose to Lead the Forensic Data Analysis Division, overseeing all analysts and data operations nationally. He later spent nine years as a Senior Economic Crime Analyst at Sasol, before founding WLM Analytics in 2021.

Since establishing WLM Analytics, Warwick has been appointed to a Ministerial Committee, a Departmental Advisory Committee for the Department of Home Affairs, and a Ministerial Review Committee for the Government Printing Works.
