Mental health start-up Siggy raises US$6 million pre-seed round led by Village Global

The story so far, in brief; the legwork, and the full article, stay with the original outlet.

Siggy, a New York mental health start-up, has closed a US$6 million pre-seed round led by Village Global, its first outside money. The idea is to fill the gap between appointments. Patients start with a free AI conversation about their history, then see a licensed clinician by video, who diagnoses and prescribes where needed. Between visits, they talk to Siggy's AI and do daily check-ins on sleep, mood, medication and physical state, optionally adding data from a Whoop, Oura or Apple Watch. All of it becomes the Siggy Score, a daily number out of 100 that both patient and clinician can see, and the software flags changes for a clinician to review. Siggy does not prescribe controlled substances and is not a crisis service. It takes commercial insurance in all 50 states, is expanding into public insurance programmes, and will be free for veterans permanently.

The founders have done this sort of thing before. CEO Jonathan Sabbagh co-founded Journey Clinical, which supports practices offering ketamine-assisted psychotherapy. COO Edvard Engesæth, a doctor, co-founded Nurx, which by his account passed 2 million patients and a US$100 million annual revenue run rate before merging with Thirty Madison in 2022.

That history shows in the cap table. Albert Wenger of Union Square Ventures, Mercury co-founder Immad Akhund, Toyin Ajayi through Coalition Operators, PsyMed Ventures, Mystic Ventures and Gokul Rajaram also joined, and several had already backed one or both founders. "That's why I'm betting on them again with Siggy," Akhund said.
