Why we're building this

Mental healthcare is broken — and we've spent our careers learning exactly where.

Between Journey Clinical and Nurx we touched over two million patients. The same pattern repeated everywhere: people who wanted help, clinicians who cared, and a system that could not keep up. Wait times measured in months. Fifteen-minute appointments for problems that take an hour. Insurance that covers the prescription but not the conversation.

We started SiggyMD because AI finally makes it possible to close that gap — not by replacing clinicians, but by giving every patient a tireless, always-on partner that handles the 90% of psychiatric care that doesn't require a human in the room, while a board-certified psychiatrist supervises every clinical decision.

“Everyone, everywhere deserves to be heard & cared for.”

The road ahead

From a handful of beta partners to clinician-supervised psychiatric care in all 50 states.

We're building Siggy to become the foundational AI layer that hospitals, employers, and payors rely on for mental health programs.
