When Aurelian Briner's wife was diagnosed with type 1 diabetes about twelve years ago, the hardest questions kept coming back to the plate: how many carbs are in this or how big is this portion? Aurelian, a product manager with a business background and an entrepreneurial itch, decided that was a problem worth solving. In 2017 he co-founded Snaq, and today the app has more than 300,000 registered users and around 20,000 monthly active users around the world.
In this episode, Rob and Aurelian trace Snaq's evolution from a photo-based carb counter, to a platform that connects meals with CGM, pump and activity data, to the AI Nutritionist, a 24/7 companion built to help people reach their nutrition goals. They also dig into what it takes to bring AI into healthcare responsibly: fast product iteration on one side, slow and careful clinical validation on the other, and why both matter.
Rob makes his case: he doesn't want your vibe-coded diabetes app. Not because building your own tools isn't exciting (it is), but because there's a huge gap between a weekend prototype and a product that's used, trusted and clinically backed. Aurelian breaks down Snaq's moat (users, data and clinical validation), shares an MIT finding that app releases roughly tripled while engagement stayed flat, and explains why building got easier for everyone while marketing got harder.
Snaq's published RCT showing a 6.6% time-in-range improvement on top of AID systems, upcoming research on the AI Nutritionist versus standard of care, a US study on T1D pregnancy (one Aurelian's family lived firsthand), the shift from reactive apps to proactive AI agents, and the founder lesson Aurelian would give his younger self: it always takes longer than you think, so make sure you care enough to stay.
