Siggy Raises $6M Pre-Seed for AI-Assisted Mental Health Care

How the service works

Sabbagh says Siggy targets a gap in care: therapists and prescribers often work separately, and a patient may see a therapist weekly but a prescriber only briefly every few months. Patients start with a free AI conversation about their history, then meet a licensed clinician by video, who reviews it, makes a diagnosis and prescribes medication if appropriate.

Between visits, patients can talk to the AI and complete daily check-ins on sleep, mood, medication and physical state. Those answers, combined with optional data from wearables such as Whoop, Oura or Apple Watch, produce a daily "Siggy Score" out of 100 that both patient and clinician can see. A change in the score is flagged for clinician review, and patients get weekly check-ins during their first eight weeks.

Clinicians decide whether to continue or adjust treatment and handle medical questions. Siggy does not prescribe controlled substances and is not a crisis service, the founders said. Patients can keep their existing therapists.

Insurance and next steps

Siggy accepts commercial insurance in all 50 states and is expanding into government programs; it will be permanently free to veterans. The company recently began accepting paying patients ahead of its public launch.

The funding will go toward hiring clinicians and engineers, building the software and handling regulatory requirements. Next, the founders plan to test the service with paying patients before expanding further. Engesæth said Nurx grew to more than 2 million patients before merging with Thirty Madison in 2022.
