Monica Singer qualified as a Chartered Accountant. After working for the SA Institute of Chartered Accountants and the World Bank, she became CEO of STRATE, a company set up to digitise the Johannesburg Stock Exchange (JCSE).  She drove this challenging project with great success. In 2015 she left STRATE to become an evangelist for Blockchain, a technology she sees as having the potential to eliminate many forms of financial corruption.


Monica Singer is a Chartered Accountant (CA) and a Wits University alumnus. There are two phrases that characterise her interesting and significant career – these are “anti-corruption” and “digital transformation”.

After moving from her native Uruguay to South Africa in the late 1980s and qualifying as a CA Monica joined the World Bank as an advisor on how to eliminate fraud and corruption around countries receiving funds from the World Bank. In the mid-90s she became CEO of STRATE, a company set up to digitise the Johannesburg Stock Exchange (JSE) which up until then had been completely paper-based. She had great success in driving this really challenging task and turning our Stock Market into one of the best in the world. The World Economic Forum recognised SA as having one of the top 3 most progressive central securities depositories in the world in 2012

In 2015 she read about blockchain and Bitcoin and realised that this was what she had always been looking for … a way to eliminate corruption and fraud and financial and securities markets. When she couldn’t convince the Board of STRATE to adopt blockchain, she decided to leave her top position in an organisation she had built over 19 years and become an evangelist for block chain.  This is what she does as a Professor at UJ, as an ambassador of ConsenSys, a leading international blockchain company, and in dozens of other ways. She is also a board member of the SA Institute and Chartered Accountants.
