Some leaders amass titles in the same manner as others do certificates: they are framed, on display, and mostly ornamental. Then there are those who enter a room and alter its temperature. Their genuine conviction about the work, genuine concern for the people doing it, and unwavering belief that the most powerful thing a leader can do is to uplift others are what make them harder to fake than authority, not because they demand attention. The second type of leader has always been individuals like Dr. Lisa Du Plessis.
Her story does not begin at the top. It begins in the detail- in the discipline of finance and in the quiet confidence that comes from mastering a craft before claiming a seat at the table. Over the years, that foundation grew into something far larger: a leadership identity built on trust, shaped by challenge, and powered by a deep, personal investment in the people she works alongside. Today, as Deputy Chief Executive Officer of Sapphire Risk Transfer, Dr. Lisa brings all of it to bear- every day, in every room, at every decision point that matters.
She is not the loudest voice in the building. She does not need to be. What Dr. Lisa has built, at Sapphire, across the African insurance landscape, and for the careers of the professionals she has mentored, speaks with a clarity that no headline ever could.
From Numbers to People: An Evolution Worth Studying
Dr. Lisa did not arrive at executive leadership fully formed. She arrived there, having done the hard, honest work of growing into it.
Her early career was built on technical strength. She was the kind of professional who went deep into the detail- financial precision, individual excellence, and a sharp instinct for what the numbers were saying. That foundation served her well. But as Dr. Lisa moved into more senior roles, she began to notice something important: the greatest results she was seeing were not coming from any one brilliant individual. They were coming from teams that trusted each other, from cultures that made people feel safe to speak up, and from systems that translated vision into action.
That observation changed her. Dr. Lisa moved her focus deliberately, away from being the person with all the answers and toward being the person who builds the conditions for others to find them; from problem-solver to capability-builder. It is a shift that sounds simple; however, it is anything but.
Leading with Clarity, Not Just Confidence
Dr. Lisa doesn’t search for buzzwords to describe her leadership philosophy. She talks about clarity, discipline, and the daily, unglamorous work of making sure people understand not just what the strategy is, but why it matters and how their work feeds into it.
At Sapphire, her role as Deputy CEO places her at the bridge between the company’s long-term vision and its day-to-day reality. She breaks ambitious goals into practical targets that teams can act on today, this week, and this quarter. Dr. Lisa holds regular check-in sessions- not to control, but to listen, recalibrate, and keep the organisation moving in the right direction.
“A vision without discipline just becomes an aspiration.”
That one line carries the weight of Dr. Lisa’s entire approach. She is bold about direction and disciplined about execution. She understands that it takes both- ambition without structure leaves teams spinning, and structure without ambition leaves organisations standing still.
She also leads through influence, not just authority. She believes trust is not handed to a leader because of a title. It is built slowly, through consistency, through following through on commitments, and through the simple act of listening before deciding. In Dr. Lisa’s teams, everyone feels heard and feels like part of the solution. That is not accidental. That is a design.
Steady in the Storm: A Lesson from COVID
Every leader faces a defining test. For Dr. Lisa, that test arrived with the COVID-19 pandemic- a crisis that hit companies, communities, and individuals with a force very few had prepared for.
The pressure was everywhere at once- revenue uncertainty, team anxiety, and families struggling. There were decisions that needed to be made with incomplete information, under extraordinary stress, in real time. There was no playbook for it.
What Dr. Lisa learned during that period was not about strategy or finance. It was about human beings and what they need from their leaders when everything feels unstable. They do not need a leader who pretends to have all the answers. They need one who stays calm, tells the truth, and gives people something to hold onto- a clear plan, an honest assessment, and a sense that someone is steady at the helm.
She leaned into honesty. She communicated openly about what the company was facing and exactly what steps were being taken. She made it safe for people to be worried, while making sure they also felt guided. That experience reinforced something she already believed: leadership in hard times is not about being unshakeable. It is about being trustworthy.
Growing People: The Work She Loves Most
Dr. Lisa is driven not by strategy or growth targets or market position. She is driven by people. She identifies high-potential individuals early and deliberately places them in situations that push them- not to the point of failure, but to the edge of their current capability. Because that, she firmly believes, is where growth actually happens. Not in the comfortable and familiar, but in the stretch.
She applies the same philosophy to herself. Five years ago, when Dr. Lisa began working toward a transition from CFO to CEO, she recognised that her financial and technical skills, strong as they were, would not be enough on their own. She needed to expand her strategic relationships, particularly with international reinsurers, who sit at the core of Sapphire’s business model. Dr. Lisa made that a deliberate, focused priority. She put in the work. Those relationships are now among her most valuable professional assets and a meaningful driver of the company’s commercial strength.
Holding the Balance: Innovation Meets Stability
In a world that demands constant adaptation, Dr. Lisa holds a clear-eyed view: stability and innovation are not opposites. They are partners. And getting the balance right is what separates businesses that thrive from those that simply survive.
At Sapphire, the strategic pillars are direct: Best People, Best Data, Best Solution. Everything innovation-related must connect to these pillars. Dr. Lisa encourages her teams to experiment- to test new ideas in controlled, managed ways that do not put the whole organisation at risk. She creates the space for learning without leaving the business exposed.
This is not an innovation for its own sake. It is purposeful, disciplined exploration, anchored to a clear sense of where the company is going and why.
Staying Human in a Demanding Chair
For everything she has built professionally, Dr. Lisa is grounded in something far simpler than ambition. She is motivated by impact; not the kind measured in quarterly reports, though she cares about those too, but the kind measured in people. In moments when a team member realises they are more capable than they thought. In the growth of a junior professional who, two years down the line, is leading a project she once helped them believe they could handle.
Dr. Lisa stays grounded through deliberate choices. She seeks honest feedback, not validation. She surrounds herself with people who challenge her, not those who simply agree. She makes time to reflect before making big decisions. She stays connected to family, to mentors, and to life outside the office, because perspective, she knows, cannot be manufactured. It has to be lived.
Dr. Lisa is also honest about her own imperfections. She does not lead from a position of having it all figured out. She leads from a position of genuine commitment to doing the work, to caring for the people in her charge, and to holding herself to the same a higher standards she sets for everyone else.
“Leadership is a responsibility, not a title,” states Dr. Lisa.
That is the sentence that stays with you after any conversation with Dr. Lisa. Six words that carry an entire philosophy. She does not treat her role as something she has earned and now holds. She treats it as something she is constantly working to deserve- through honesty, consistency, and a quiet, steady belief that people, when they are genuinely supported, can do extraordinary things.
