More than two million people across the United States will receive notice that their personal and sensitive health information was stolen earlier this year during a cyberattack at Postmeds, the parent company of online pharmacy startup Truepill.

News of the data breach also appeared to catch off-guard healthcare startups that previously relied on Postmeds to fulfill their customers' prescriptions.
