Joshua Calum Antoniou
Business Development Manager
A commercially driven professional with a unique background spanning professional football and M&A business consultancy — bringing leadership, strategic thinking, and strong client relationships to every engagement.
A commercially driven professional with a strong foundation in leadership, communication, and team management — built across a unique career spanning professional football and the business world. Over seven years in professional football, I progressed from assistant to lead coaching roles, gaining extensive experience managing diverse teams and performing under pressure.
In recent years, I have successfully transitioned these skills into a client-facing, commercially driven environment. I work with a wide range of stakeholders, preparing and facilitating business transactions, conducting valuations, and developing new revenue streams. I take pride in building strong professional relationships and maintaining high standards across every area of my work.
