When I have felt stuck in my career, I have been lucky to have the advice of some incredible founders and leaders. I want to share some scale up lessons learned, through this series called “Defying Gravity”. Each month or so, I’ll sit down with the entrepreneurial heads behind some of Australia’s leading scale ups. This is for founders who feel they could learn from people who’ve gone before them. But more than that, it’s for anyone who might feel they need to learn, or grow, or change, to remain successful. For those who are curious about what works and what doesn’t at different stages of company growth, and what they might need to do differently. And who best to hear it from, than some of the most incredible founders, who lead the unicorns and scale ups I have had the privilege to know over the years.
In this episode, we sit down with Julian Elliott, infectious disease physician turned founder of the global evidence platform Covidence, to unpack how the world makes sense of science in an era overflowing with information - and misinformation. Julian explains how his years working in HIV care in Cambodia exposed a critical problem: clinicians often couldn’t access the research they needed to make the best decisions for patients. That experience ultimately set him on the path to building Covidence, a platform now used by governments and academics worldwide to cut through the 'firehose' of scientific slop and fraud.
Julian reflects on Covidence’s evolution from a machine-learning research project into a nonprofit powering rigorous evidence synthesis, and why LLMs, while transformative, still fall short when it comes to producing high fidelity, reproducible scientific understanding.

Dr Angela Lim shares her journey from medicine to entrepreneurship, driven by a determination to fix a mental health system struggling with long wait times, rising youth need, and inefficiencies that left too many people without timely support.

Angela also speaks candidly about the role of augmented intelligence in mental health - not as a perfect solution, but as a meaningful step forward - and offers grounded insights on leadership, focus and hiring shaped by her experience navigating one of New Zealand's most challenging sectors.

Kai Van Lieshout, founder of Lyrebird
Kai Van Lieshout, founder of Lyrebird, knows what it really takes to build one of Australia’s fastest growing health tech companies. In this episode, Kai shares the unexpected challenges of innovating in an industry where the stakes are high, the systems are complex, and new technology often lags years behind other sectors.
He talks about the human side of adoption - why earning trust from doctors and hospitals was the hardest part, and how deeply understanding clinicians’ pain points became Lyrebird’s superpower. He reflects on the surreal moment when doctors not only embraced the software but pushed their own hospitals to implement it.
We also explore the realities of raising $12M in capital, the opportunity costs behind that decision, and how he balanced growth with solving real-world problems for practitioners. It’s a thoughtful, grounded window into building mission-driven technology in one of the most challenging environments there is.

Claudia Batten, Founder and Entrepreneur
In this episode, I sit down with one of New Zealand’s favourite entrepreneurs, Claudia Batten - trailblazer, startup builder, and global champion for Kiwi businesses. With multiple successful US ventures behind her, she now works across a number of boards and brings her signature candour, humour, and hard-won wisdom to the conversation.
A longtime friend (and one-time fellow law school tutee!), Claudia dives into the truth of entrepreneurial life: the challenge is the point. She reveals why “execution by fire” forges real problem solving muscle and why great founders trust their ability to figure anything out.
We explore her view of business as one giant, messy puzzle, constantly shifting, sometimes breaking, and always requiring you to simply find a place to start. From transformation in the boardroom (“everything is breaking because everything needs to be fixed”) to her wonderfully squiggly career from startup founder to NZTE leader, Claudia offers an inspiring, practical take on what it really takes to make bold decisions and build bold companies.

Raw, real, and full of wisdom - this one’s for anyone bold enough to build what’s never been built before.
