Building Her Body API – Christy Fernandez-Cull

In this episode of Spread Love in Organizations, Naji Gehchan welcomes Christy Fernandez-Cull, CEO of DaVinci Wearables and a trailblazer in tech and health innovation. Christy shares her inspiring journey from childhood curiosity — designing a cereal dispenser to let her hardworking parents sleep in — to leading groundbreaking work at companies like Apple, Waymo, and Google. With a PhD from Duke and an MBA from MIT, Christy blends deep technical expertise with visionary leadership, always guided by a moral compass instilled by her family and a relentless curiosity about the world.

Christy introduces her current venture, DaVinci Wearables, with the bold ambition of becoming the “body API for better health.” She describes a future where garments not only clothe us but also provide real-time biometric insights, especially focused on women’s health, a historically underserved field. With partnerships across universities and health systems, DaVinci is building a wearable ecosystem that tracks hydration, hormones, nutrition, and physical activity, empowering users through a smart companion app that educates and nudges healthier habits. Their unique platform blends data, personalized coaching, and community, aiming to democratize body intelligence for every stage of a woman’s life.

Throughout the conversation, Christy speaks candidly about the challenges and joys of entrepreneurship, especially as a female founder in health tech. She emphasizes the importance of empathy — both toward others and oneself — and encourages founders to stay anchored in purpose by connecting directly with the people they serve. Christy’s reflections on leadership, equity in women’s health, and the role of love and service in organizations offer powerful inspiration for healthcare leaders seeking to drive meaningful change.

"If you need to feel inspired, go directly to your customer… They’ll remind you why you started."
