If you're sick, nobody really knows what you should to do get healthy. Your doctor gives generic advice and rarely follows up, and you're left to Google and hearsay to figure out the best diet, exercise, and drugs to get better. Today, you have to just try things and see if they work. Our app lets anyone run experiments on themselves to figure out what actually works. People use us to find the optimal dose of a drug, determine the impact of a habit, or figure out whether a supplement does anything. The product comes from Zain's own experience caring for his sick mom. Our users' pain points are literally painful: chronic pain, sleep issues, brain fog, flare-ups, and more. We have a chance to use design & engineering to help people going through the toughest moments of their lives. As we scale, we are building the world's first continuously-learning knowledge base on human health, and unlocking a revolution in precision medicine for everyone on the planet.
