How Heidi Health Built Its Accuracy Advantage (Re-release ep)
Manage episode 524923287 series 3611203
Episode Summary
Heidi Health has quietly become one of the most widely used AI products in Australia, powering nearly two million clinical visits a week and transforming how doctors document care. In this re-release of the year’s most downloaded episode, Georgie sits down with Heidi cofounder and CEO Dr Tom Kelly to unpack how this runaway success was built, why clinicians trust it, and what the rise of medical agents means for the future of healthcare.
Tom shares the technical decisions that shaped Heidi’s accuracy advantage, including the surprising reason they ditched live transcription, how batch processing boosts note quality, and why a two percent gain in transcription accuracy can unlock a forty percent jump in adoption. He also breaks down what non technical founders absolutely must understand about LLMs, how he evaluates off the shelf models, and why compliance and regional infrastructure shape every product decision.
The conversation stretches far beyond medical notes. Tom dives into why rag is failing many real world use cases, how giant context windows could reshape patient care, and which AI startups may struggle as models get faster and cheaper. There are hot takes on personal branding, the attention hacking era, and the types of B2B SaaS companies he believes will not survive. Plus, Georgie and Tom play Late Stage Startup Bingo and share two very usable AI hacks.
This episode is a sharp, founder friendly deep dive into building AI products people rely on in the real world. A perfect refresher as we head into a huge 2026 for Australian AI.
