“Australia is one of the best places in the world for science, for deep tech. I mean, like, for health, like Andromeda, um, Everlab, like there's Heidi Health.”
“So if I think about that from Heidi Health, a merchant that we worked with, or an AI business that we worked with very early on, it was like they built that infrastructure to support, which was very much a domestic business at the time.”
“We had Tom, uh, Dr. Thomas Kelly from Heidi Health on the show. It's Australia's biggest, uh, medical transcriber.”
“Canva made that decision and, and Heidi Health has started targeting enterprise. Like when you used to think about enterprise, we were thinking about about like the Oracles and the Salesforces of the world.”
