Walk through the front doors of Medi Response and the first sign you see says: life matters and people come first.

Annastacia Wainaina sits down with Saul, global CEO of Medi Response, an organisation delivering pre-hospital emergency care and aeromedical evacuation across the world. His teams run ambulances across South Africa, staff mining, oil and gas sites, and operate in hostile environments including Iraq and Afghanistan.

This is leadership shaped by life and death.

Saul explains why AI belongs in the medical pack as a tool rather than as the decision maker, and why his clinicians are told to fall back on their training and double check what the algorithm suggests. He describes the escalation pathways where questioning a decision is commended, not punished.

He speaks honestly about mental health in emergency care, and how the belief that a practitioner who cries after a scene is weak had to be dismantled. He argues that culture cannot be taught, only cultivated, and that empathy must run from the executive all the way to the person taking the rubbish out at the gate.

Then he shares the two stories that made him. The man trapped under a heavy vehicle who died the moment it was lifted, and the lesson that you can prepare every step and still not control the outcome. And the baby he delivered in an ambulance, now an adult walking past him years later.

His closing advice: go back to basics, build the foundations, and remember that if you are the most clever person in the room, you're in the wrong room.

The Human Edge Podcast explores what it really takes to lead, care and create change at the edge of human possibility.

If you have ever undercharged, wondered why your pipeline is dry or felt like your expertise is not being valued the way it should be, this is the conversation you needed years ago.
Jane Anderson is one of the world's leading consulting coaches, working with thought leaders, consultants and advisors across more than 40 countries. She is the author of multiple books, a certified speaking professional and a growth strategist whose clients have built some of the most recognised independent practices in their fields.
In this episode of The Human Edge, Jane and Annastacia cover: why pricing is a supply and demand question, not a self-worth one. The million dollar problem being solved for $500 and why that has to change. Why you are the non-negotiable and the thing no competitor can copy or undercut. The honest test that tells you if you have a business or a very expensive hobby. How she nearly walked away from everything in 2020, ran a free event instead, had 500 people show up and created over $50 million worth of IP in two days. The difference between an expert and a thought leader, and what it takes to make the shift. And a closing thought that every person sitting on their expertise needs to hear: you have got more in you than you think.

Over 50% of Kenyans cannot access primary healthcare. Most manage their own symptoms until a small condition becomes an expensive emergency. Dr. Karl Daniel decided to change the system rather than keep treating patients one at a time.
Dr. Karl is the CEO of Tibu Health Kenya, a company placing minute clinics inside pharmacies to make quality primary care accessible and affordable across Kenya and Uganda. He is a trained doctor with epidemiology training and an MBA, and he leads at the intersection of healthcare operations and human experience.
In this episode of The Human Edge, Dr. Karl and Annastacia Wainaina cover: why 50% of Kenyans cannot access primary care and how the system loses people in the cracks. The moment he knew the stethoscope was no longer his most powerful tool. What he learned about leadership from a superintendent in Turkana who told him: you lead and the money will follow. Why humanity is a clinical strategy, not just a value. How belonging in healthcare is clinical, not optional. The minute clinic model and why colocating inside pharmacies keeps costs low without cutting care. What preventive healthcare looks like inside a pharmacy where people already shop. The role of trust in medicine. And what is coming next for Tibu Health including supermarkets, HPV vaccines and audiology services.

What do you do when the healthcare system that was supposed to save your family fails them, not once, but five times?
Dr. Levi Cheruo is the CEO and Founder of Doctors Explain Digital Health Group, a movement democratising healthcare access across Africa through technology, empathy and relentless conviction. Before he built it, he lost his father to misdiagnosis, his fiance to an ignored headache that turned out to be an advanced brain tumor, and four others to conditions that need not be killing anyone in this day and era.
From that grief, he made a decision. He could wallow in pity. Or he could do something. He chose to do something.
In this conversation with Annastacia Wainaina on The Human Edge, Dr. Levi Cheruo speaks with the kind of honesty and conviction that only comes from someone who has looked the system in the eye and refused to look away.
In this episode:
The loss of his father, his fiance and four others to preventable deaths, and what that season of grief did to him as a human being. Why he says the healthcare system does two things well, it accelerates your untimely death and then it collects your money. The moment he stopped waiting for the rain and decided to become the rainmaker. How being raised by generous grandparents who cooked extra food for neighbours shaped his belief that every life matters regardless of class. Why he sees his family in every single patient and what that does to how he leads. What AI in the hands of a midwife at a rural clinic can change for the woman on the table at that moment. Why giving birth should not be a death sentence, and how information in the right language saves lives money sometimes cannot. His honest and unfiltered assessment of where Kenya and Africa sit on the digital health journey. And the one sentence he would say to his father and his fiance about what he is building in their memory.
The Human Edge is hosted by Annastacia Wainaina, for leaders who believe that equity, empathy and integrity are not soft skills. They are the foundation of everything that lasts.

— How she rebuilt her mindset during three months of complete non-weight-bearing recovery — and what that taught her about self-leadership
