Susie is one of the creators of the M-PESA money transfer service. In 2005 whilst employed by Vodafone Group she developed and ran M-PESA as a small pilot in Kenya working with the local operator, Safaricom. She redeveloped this system to be suitable for national launch in 2007 whilst recruiting and training the local team. Susie then facilitated the M-PESA launch in Vodacom Tanzania whilst supporting growth in Kenya and developing new functionality. Next, she supervised the launch for Vodacom South Africa then led a team to identify the technical and commercial requirements for interconnection with conventional financial services. M-PESA in Africa currently has 20 million active customers and there are now more than 180 similar services operating in over 70 countries.
