When billion-dollar decisions collide with personal struggles, Ariane de Bonvoisin is the person many leaders call. She is a leadership coach and advisor who combines business strategy with human insight, helping clients navigate both boardroom challenges and private turning points.

With experience that spans global boardrooms, venture capital, bestselling books, and keynote stages, Ariane blends intellect and intuition in a way that serves leaders at critical moments. To some, she is a strategist. To others, a guide. To all, she is a steady voice in times of change.

Even though she tends to operate below the radar and has until recently stayed somewhat out of the public eye or social media, according to her clients, she has an extraordinary impact in all aspects of their lives.

A Global Foundation

Raised on several continents, Ariane developed adaptability early and grew comfortable with the unfamiliar and prepared her to help people and now companies through change. Her international upbringing sparked a lifelong interest in growth, humanity and transformation. Today, she lives between the US and Europe, balancing life as a wife and mother while coaching clients across many countries.

Her academic path reflected that same focus. At the London School of Economics, she graduated with honors before earning admission to Stanford’s MBA program, where she became the youngest student in her class. These achievements underscored her belief that progress is driven by having a sense of what is worth doing with your life and determination.

From Corporate Leadership to Meaningful Ventures

Ariane’s career began at Boston Consulting Group, where she worked in twelve countries, including South Africa, Iceland, Hong Kong, and Russia. She later joined Bertelsmann in New York, working alongside the CEO and Board. At Sony, she helped launch a corporate venture arm, and Time Warner recruited her as the first partner in a $500 million digital media fund. By her early thirties, she was investing in early-stage companies and helping shape the digital landscape.

Eventually, Ariane stepped away to pursue projects rooted in meaning. She joined the Himalayan motorcycle documentary The Highest Pass as the only woman participant and co-created A Day in the Life of Africa, a project that brought together one hundred photojournalists to capture daily life across the continent, raising funds for communities in need.

The First 30 Days: A New Direction

Her next chapter centered on the subject of change itself. Ariane founded The First 30 Days, a venture designed to help people navigate major life transitions. The project evolved into a bestselling book that introduced nine principles of change and was featured widely, including by Oprah and other media outlets.

The response then opened a new path. CEOs, founders, and professionals began asking her for one-on-one guidance. What started as a publishing project became a career in coaching leaders in various industries, from education to AI, to healthcare and sports, through both personal and professional transitions.

Coaching at the Intersection of Business and Life

Today, Ariane advises unicorn CEOs, venture capital partners, Fortune 100 executives, and athletes seeking peak performance. Her clients range from Amazon and Google to Red Bull, L’Oréal, and the World Bank. She has delivered keynotes in more than a dozen countries and spoke to 7,500 women at Oprah’s conference in South Africa.

Her coaching spans business and personal challenges. She may refine a board presentation, guide IPO strategy, or address co-founder conflicts. Just as often, she supports clients through marriage strain, fertility challenges, or caring for aging parents. Her clients describe her as both strategist and confidante—someone who provides clarity and a deep sense of caring, when it is most needed.

As Ariane put it, “Change and Uncertainty are the words of the decade. Everyone is feeling them. The new leadership frontier belongs to people who can navigate crazy change and show up with crazy certainty.”

Expanding Reach Through Books and Media

Ariane has been recently inspired to help parents and the younger generations. Her children’s series Giggles and Joy, endorsed by Goldie Hawn, teaches life lessons to kids. Spirit Mama, her most recent book, offers guidance through fertility and early motherhood. Her forthcoming book Feisty: A Handbook for Female Leaders, captures lessons from decades of coaching.

She is also preparing to launch a new podcast, Not in the Bio, which will share the authentic, unfiltered sides of inspiring people. It follows her earlier show, Change Nation, which featured early interviews with figures such as Simon Sinek and Tim Ferriss and became one of the first widely followed podcasts in its category.

Commitment to Service and Impact

For Ariane, leadership is inseparable from service. She helped raise funds and build a clinic in Mozambique, supports a school in Johannesburg, and contributes to educational initiatives in the Himalayas.

She also coaches selected individuals pro bono if they meet her criteria. As she explains, “They must be a good human, have a good idea, that does good for humanity oh and they must be coachable.”

Living With Change and Certainty

Ariane believes the most powerful coaching begins not with answers, but with questions:

• If you can be absolutely sure of one new thing happening in the next 12 months, what would it be?
• If someone took over your whole life tomorrow, what is the very first thing they would change?
• What does the world need from you right now? How must you be of service?

She also reminds clients that achievements alone rarely sustain fulfillment. According to Ariane, “Without contributing to your fellow human beings and maintaining a healthy body, unicorn career ascents and Olympic gold medals will eventually feel meaningless. I have seen this often—the founder exits her company or the athlete achieves his dream and then what? They face the eternal question: Is this it?”

When asked what she returns to first in coaching, Ariane is clear: “You can have 1000 dreams if you are healthy. You only have one if you aren’t. Physical, emotional, mental and spiritual health are the foundation. Then we can talk about what is really worth doing with your life.”
