Worth Oil – Dexter Dunworth takes another risky leap into the unknown!

David Tudehope left the finance world in the early 1990’s with a dream to service small to medium business who complained of poor service and overcharging by the monopolist at the time, Telstra.  Tudehope wasn’t a digital expert nor a highly trained computer engineer. But he understood numbers, and that customers wanted good service, not delays and obfuscation. So he had his brother Aidan started a small business they called Macquarie Telecom, back in 1992, with only the savings the pair could scrounge up, and forged headlong into the ultimately capital-intensive telco space. This is long before the internet and smart mobile phones. But they took on the slow-to-change Telstra and stuck to their mission of offering better customer service and cheaper prices to the business customer.  In just over 3 decades they’ve built (now named) Macquarie Technology Group into one of the Top 300 listed companies in Australia, with a market capitalisation of over $1.5 billon, offering major clients like the ATO, Officeworks and PayPal still telecom, but now cloud-based, cyber security services as well as massive investments in data centres to support the boom in AI.  David appeared on the Australian Financial Review’s Rich List 2024 alongside brother Aidan with an estimated net worth of over $900 million.

Since Dr Sarah Crowe had her lightbulb idea, and invented her completely mobile, vision testing and glasses kit, then ran a trial in remote Papua New Guinea and started to show  the impact her OOXii Vision Kit could have, to medical professionals in India and Vanuatu, she was inundated with positive reaction. Here was a complete system not only offering mobile eye testing, but also durable glasses frames, with prescription lenses in them, were then dispensed on the spot to people in remote or under-served communities, thereby improving their vision right there and then, in their home communities. It was life-changing.  A fantastic entrepreneurial idea to fix a massive global problem.

But Sarah’s journey with OOXii Global and her mission to help fix the world’s vision has not been without its challenges and significant hurdles along the way.

Listen to Dr Sarah Crowe take up the story.

While navigating Australia’s mental health system to deal with his personal assessment and ongoing care, entrepreneur Zac Altman felt frustrated and thought, quite simply, there must be a better way to help the huge number of adults with ADHD get the proper care and support they need. To help solve what he saw as a very large unmet demand problem, Zac created and built the start-up Kantoko, a telehealth service offering online assessments and ongoing care for adults with ADHD, but using an unusual business model – subscription services. Kantoko has been operational since early 2024, with patients accessing Kantoko’s team of experienced ADHD psychiatrists and GPs focusing on mental health.
