For founders of healthtech companies, forging innovations within the healthcare industry means more than developing an easy-to-use app. In truth, protecting patients’ sensitive data is essential to building a successful healthtech company, and it requires adhering to the Health Insurance Portability and Accountability Act (HIPAA).
