🧬 Small Community, Long Journey: The Power of Relationships in Biotech | Caitlyn Krebs (Part 3/4)
April 20, 2026
In this episode of The Biotech Startups Podcast, Caitlyn Krebs traces her path from a gut-punch company shutdown on maternity leave — which unexpectedly forged a key cofounder relationship — through the digital health boom at Rock Health, to her role as COO at Neurotrack, where an eye-tracking Alzheimer's test launched to 137 countries within days and led to selling cognitive risk scores to Japanese life insurers as the only woman in the room. She closes out her pre-Nalu journey at BlueStar Genomics, where hard lessons in capital discipline and the dangers of scope creep shaped the focused, founder-ready mindset she brings to building Nalu Bio today.
