Siggy raised $6 million for a mental health service that uses AI to track patients between visits with licensed clinicians. It takes insurance in all 50 states.
Siggy, a New York startup, has raised $6 million to build a mental health service that uses AI to keep track of how patients are doing between appointments with licensed clinicians. The company told Crunchbase News the round is pre-seed, meaning a very early stage of funding. It is the company's first outside money.
Therapists and the clinicians who prescribe medication often work separately. A patient may see a therapist every week but get only a brief appointment with a prescriber every few months. That leaves little time to talk about changes in symptoms or medication side effects. CEO Jonathan Sabbagh says he ran into this problem himself.
Patients start with a free AI conversation about their history. Next, they meet a licensed clinician by video, who reviews that information. The clinician makes a diagnosis and prescribes medication if appropriate. After that, patients can keep talking with the AI and check in daily on sleep, mood, medication and how they feel physically.
The company says it aims to spot hard stretches earlier, including when someone says they feel fine but their sleep is getting worse.
Clinicians, not the AI, decide whether to continue treatment or adjust medication. They also handle all medical questions. Siggy does not prescribe controlled substances and is not a crisis service. Patients can keep seeing their current therapists while using it.
Siggy accepts commercial insurance in all 50 states and is expanding into government insurance programs. Patients can also pay directly. Costs for insured patients vary by plan. The founders say the service will be permanently free for veterans.
Sabbagh co-founded Journey Clinical, which supports practices offering ketamine-assisted psychotherapy. COO Edvard Engesæth, a physician, co-founded Nurx, an online provider of birth control and other care. He says Nurx grew to more than 2 million patients before merging with Thirty Madison in 2022. Village Global led the round, and several investors had backed one or both founders before.
The founders began building Siggy in late 2025. It recently began accepting paying patients ahead of its public launch. Next, they plan to test the service with paying patients before expanding. The money will go toward hiring clinicians and engineers, building the software and meeting regulatory requirements. A planned feature would let patients share information with other providers and loved ones.
Not yet known is how well the approach works. The material from the company shares no results on patient outcomes.
Siggy is an early bet that AI check-ins can fill the long gaps between mental health visits, but the company has not shared results yet.
