Regulation Is Not the Enemy of Speed: Tauseef Mehrali on Building Safety Culture at 400 Million Users
Prove It! with Dr. Tauseef Mehrali, VP of Regulatory Science, Flo Health
Audio coming soon · 52 min
Paul Wicks sits down with Dr. Tauseef Mehrali, GP, former VP of Medical Safety at Ada Health, and now VP of Regulatory Science at Flo Health, the world's largest femtech platform, for a deeply practical conversation about what it actually takes to build safety and regulatory rigour into digital health products at scale.
Flo has over 400 million downloads and nearly 80 million monthly active users. When something goes wrong at that scale, the harm is invisible, insidious and potentially enormous. Tauseef's job is to make sure it doesn't.
Plus: what book should be on the shelf instead of Blitzscaling, and why Tauseef might just have to write it himself.
