Lake Macquarie entrepreneur Jennifer Holland is set for her next big invention.
And like before, she'll use personal experience to guide her.
She won't give any hints about her next idea, except to say that it's health-related and something to improve the patient experience.
"I believe I am here to create in the healthcare space - I believed that from the moment I was born deaf," Mrs Holland, 42, said.
The mum of four wore hearing aids until age three before her hearing miraculously returned.
The experience meant she had to work extra hard on her speech and communication throughout childhood.
She had to develop methods to make things simple.
This changed her brain, giving her a knack for finding simple solutions to complex problems.
"I see a lot of complexity in the healthcare industry," she said.
"When I see a complex problem, I can see the end solution and the process to get there."
It was a visit to a GP in 2009 that led her to invent Throat Scope, an illuminated tongue depressor that makes mouth examinations easier.
As she held her first child, Ronan, a doctor struggled as he held a pen light and wooden tongue depressor to check the boy's throat.
Mrs Holland thought there had to be a better way.
After a 15-year journey in the start-up sector, which included a successful pitch on Ten's Shark Tank and a stint in the US, she sold her medical device range last month to Sydney company One Dental.
The sale included four medical devices - Throat Scope, TelScope, Ear Scope and Wound Scope - an app and two AI solutions.
While product marketing often required a "gift of the gab", Mrs Holland was "not a talker".
"I'm a doer," she said.
"For example, people would walk past our trade stand early on and I'd shine a Throat Scope light in my mouth. They'd go, 'oh my god' and stop," she said.
"If your product can't, in an instant, bring someone in and keep their attention for a split second, you have lost the battle with every other product on the market."
Mrs Holland is a big believer in "the emotional side" of product development.
"When people used Throat Scope, the feeling they had was 'wow this is easy, why didn't I think of this'.
"A lot of companies don't build empathy, emotion or feeling into their experience, particularly in the healthcare sector.
"But that is what I do."
While the female touch may be behind this approach, it can be tough for women to get start-ups funded.
Female founders receive only 3 per cent or less of venture capital in Australia and the US.
Mrs Holland would love to see this improve, but added that "I was very lucky I had some amazing angel investors".
Everything she created had a "personal connection".
"It's personal experience that drives me to have passion and purpose to create and impact people's lives," she said.
"I want to continue doing that."
Last December, her husband had heart surgery at age 46.
"Even through that experience, I learnt so much. There's an opportunity there to create," she said.
