Health Catalyst Capital


The heart beats over 102,000 times per day and reacts to everything that happens in life; meals, exercise, stressful moments, or happy memories. Cardiogram acknowledges the heart’s importance and wants to turn a wearable device into a continuous heart and health monitor that can be used to not only track sleep and fitness but also prevent strokes and save lives.
