Founder

Marcus Mang, a seasoned banker with over 22 years of experience in the banking and finance industry, played a pivotal role in shaping some of the largest financial institutions. He was a pioneer in the establishment of Citibank's CitiBusiness Division, HSBC's Commercial Banking division, and Alliance Bank's executive group during its reform under Temasek takeover. During his tenure at OCBC, he played a key role in the success of the EMM (SME) Division and achieved top sales contributions consistently, leading the largest and most prominent team nationwide.

After his successful career in banking, Marcus transitioned into corporate exercise, business and finance advisory which has since been recognized by banks for its contributions. To date, he has structured and driven investment and financing initiatives worth over RM 1 billion in capital.
