In 2019, Christiane Constantineau faced an unimaginable challenge—a Stage 3C breast cancer diagnosis, just months before the world would go into a global pandemic. Instead of succumbing to the weight of her diagnosis, she leaned into the chaos and kept her business running, even while undergoing chemotherapy. But Christiane didn’t stop there. What followed was an extraordinary transformation—she documented her journey, turning her fight into an Amazon bestselling book. This is the story of a leader who not only survived cancer but also thrived, redefining success for entrepreneurs everywhere.
Christiane Constantineau’s story is a testament to the power of resilience, strategy, and the unyielding drive to make a difference—even in the face of adversity. With an Executive MBA and a career spanning five continents, Christiane had already built a reputation as a leading CFO-to-hire and business consultant. However, her greatest challenge came not in the boardroom, but in her own body. A diagnosis of Stage 3C breast cancer thrust her into the fight of her life—but instead of retreating, Christiane took the opportunity to share her invaluable insights with the world.
When her husband asked her how other entrepreneurs would manage their businesses without her support system, she realized something profound. “I had to share what I learned—not just about surviving cancer, but about thriving in business when life throws you curveballs,” Christiane reflects. Her answer was a powerful one: share the journey. She turned her business’s operations into a real-time case study of resilience, offering other entrepreneurs a road map for navigating their own challenges.
The turning point in her journey came with the realization that true success isn’t just about financial gain; it’s about creating a business that aligns with one’s values. Christiane’s philosophy—Ikigai, the Japanese concept of finding purpose where what you love, what you’re good at, what the world needs, and what pays you intersect—became a cornerstone of her coaching and consulting practice. “Most entrepreneurs burn out because they’re chasing someone else’s definition of success,” Christiane notes. “Ikigai taught me that true entrepreneurial success happens when you align your passion with purpose.”
Christiane’s business acumen, combined with her personal experiences, set her apart in a crowded industry. She didn’t just offer theoretical business advice; she provided battle-tested, real-world strategies. From her experience as a single mother of two young children in South Africa, where she completed a prestigious year-long consulting assignment, to negotiating multi-million-dollar contracts across the globe, Christiane’s career proves that limitations are merely starting points for success.
Her global journey—spanning continents like South Africa, Saudi Arabia, Sweden, and beyond—has given her a deep, personal understanding of international markets and cultural nuances. But more than her global expertise, it’s her authenticity and ability to blend business strategies with holistic wellness that truly resonates with her clients.
Perhaps the most powerful example of Christiane’s resilience came during her cancer battle. Not only did she continue to run her business, but she also documented her experience, culminating in the release of her Amazon bestselling book Cancer Sucks…: The Journey of an Entrepreneur and Her Fight Against Cancer While Running Her Business. The book resonated with entrepreneurs worldwide, particularly those facing health crises, as it provided not just survival tips but a comprehensive approach to maintaining business operations during a personal crisis.
This was followed by her second bestselling book, Manage. Grow. Breathe: The Entrepreneur’s Guide to Success Without Burnout, which solidified her position as a thought leader in sustainable entrepreneurship. “My experience is not just a personal triumph; it’s a blueprint for others to follow,” Christiane asserts.
Today, Christiane continues to serve as a CFO and finance director for businesses globally, helping clients thrive even during challenging times. Her Harvard X certifications in resilience and happiness management are not just credentials—they’re tools she applies daily in her life and her work with clients. Her holistic approach to business—one that integrates well-being, resilience, and financial success—sets her apart as a true leader in the field.
