Profile bio

About Francois Mostert

I am an international operations and finance executive with wide, deep experience managing domestic entities while supporting global matrixed operations. Born and raised in South Africa, I earned my BCOM degree and landed my first job (KPMG) and management position there. Subsequently, I was recruited to leadership roles with KPMG, Downer EDI, and Worley, that together span Australia (New South Wales, Victoria, Queensland) and North America (Calgary, AB, Houston, TX, Denver, CO). Embracing diversity, inclusion, and equal opportunity are core matters of human dignity and respect. And as one who has lived and worked on 3 continents - 7 cities in 4 countries - I understand that cultural nuance is crucial to successful immersion and leadership. Cumulatively, this mindset has helped attract great people, and the rewards have been many and mutual. Ten promotions over 20+ years are partially the result of successfully facilitating global and domestic M&A, including DD and complex integrations requiring finance, IT, organizational structure, systems, talent, logistical, and service / product realignment. Humbled by a reputation as a 'go-to' leader, my teams have solved daunting problems by creating innovative, deployable solutions that lower costs, improve morale, halt attrition, and perpetuate partnerships and profitable agreements.► US and Australia dual citizen► Bilingual English / AfrikaansLeadership & Management Expertise:● Team/Executive Leadership● Talent Management● Finance Systems/Accounting ● P&L/Budgeting/Forecasting● Strategic Planning/Cost Control● Management/Finance Reporting● IT/ERP Alignment/Implementation● System Migration● Data/Project Analysis● M&A DD/Integration ● Legacy Agreements Negotiation● Market Expansion/PenetrationIT / Systems:Oracle, Hyperion Financial Module + Essbase, COINSPronto, MS Power BI, MS Office 365, Salesforce
