Jonathan Sabbagh and Edvard Engesæth, co-founders of Journey Clinical and Nurx respectively, raised $6 million in pre-seed funding for Siggy, a mental health startup that uses AI to collect patient histories and track progress between appointments with licensed clinicians.
Village Global led the round. Investors include Albert Wenger of Union Square Venture, Mercury co-founder Immad Akhund, Toyin Ajayi of Cityblock Health through Coalition Operators, PsyMed Ventures, Mystic Ventures, and Gokul Rajaram. The New York-based startup began building in late 2025 and recently started accepting paying patients ahead of its public launch.
Siggy addresses a gap Sabbagh identified in mental healthcare: therapists and prescribers often work separately, leaving little time to discuss symptom changes or medication side effects. The platform uses AI conversations and daily check-ins to gather information clinicians can review between visits. Patients answer history questions through an AI conversation, then meet a licensed clinician by video who reviews that information before making a diagnosis and prescribing medication if appropriate.
Between appointments, patients can talk with Siggy's AI and complete daily check-ins reporting sleep, mood, medication, and physical feelings. The platform connects to wearables including Whoop, Oura, and Apple Watch to produce a daily "Siggy Score" out of 100 visible to both patient and clinician. If the score changes, the software flags it for clinician review. Weekly check-ins occur during the first eight weeks of treatment.
Siggy does not prescribe controlled substances and is not a crisis service. Patients can continue seeing existing therapists. The startup accepts commercial insurance in all 50 states and is expanding into government insurance programs. Siggy will be permanently free to veterans.
Sabbagh serves as CEO and executive chairman of Journey Clinical. Engesæth, a physician, was an early Journey investor. He co-founded Nurx, which grew to over 2 million patients with annual revenue exceeding $100 million before merging with Thirty Madison in 2022.
