Millions are battling mental illness — these entrepreneurs are trying to tackle it via technology

In the age of social media and the internet, instant digital connectivity can paradoxically make us feel very isolated.

“People are a lot lonelier than we realize,” said Alison Darcy, the founder and CEO of Woebot, a virtual therapist that will talk you through a panic attack at 3 a.m.

Woebot is among multiple new companies looking to address mental illness. Another is Spring Health, a startup founded by April Koh that sells a digital platform designed to help companies improve their workers’ access to mental-health treatment. Both Darcy and Koh are featured on Business Insider’s list of 30 health-tech leaders under 40.
