MARIUS JOOSTE

C12 Chair since 2024

Territory Served

Marius began his career in 1999 after earning a degree in Industrial Engineering from the University of Pretoria. He immediately stepped into the world of management consulting, working across diverse industries in South Africa, Africa, and Europe. Over the years, he has built deep expertise in business management, optimization, and transformation, with a professional yet approachable style that enables him to engage effectively with stakeholders—from boardrooms to technical teams.

As an entrepreneur, Marius has founded and led two consulting firms. Quinxi, a well-respected business engineering consultancy, has a strong track record in delivering transformation solutions for clients in insurance, banking, telecommunications, manufacturing, and IT. More recently, he established Gainmaker, a niche value engineering firm focused on unlocking enterprise value through business, process, and data engineering, leveraging Microsoft technologies to streamline and automate operations.

His career took a pivotal turn when he began to wrestle with the difference between measuring success and measuring significance. The demands of corporate leadership left him questioning how to balance business impact with eternal purpose. Led by the Holy Spirit, he was drawn to Matthew 28 and Ephesians 4:12—the call to make disciples, equip the saints, and build up the body of Christ. While businesses often focus on profits, many leaders feel isolated, overwhelmed, and unaware of their potential to transform the world for God’s glory. Discovering C12 was a blessing, and during this personal “half-time” moment, Marius transitioned out of day-to-day operations in his firms to join C12’s mission, helping business leaders in the Western Cape build great businesses with a greater purpose.

Marius and his wife, Reinette, live in Swellendam, in the heart of the Overberg, having relocated from Pretoria in 2022. While their move felt like a calling, its purpose has only become clear over time. Together, they are passionate about serving Christ and raising their two boys with an authentic, living faith—one rooted in trust, belief, and action, rather than tradition alone.

An avid sports enthusiast, Marius enjoys tennis, padel, and golf, while also cheering others on from the sidelines. He is a dedicated outdoorsman, music lover, camper, and serious foodie.

Committed to serving business leaders in the Overberg, Marius brings an open, approachable, and passionate leadership style. With decades of business expertise, he helps leaders innovate, grow, and balance their lives—emotionally, professionally, and spiritually—as they walk boldly in their calling, purpose, and relationship with Jesus.
