Exclusive: Nurx And Journey Clinical Co-Founders Raise $6 million

Siggy has raised $6 million in pre-seed funding to build a mental health service that uses AI to collect patients' histories and track progress between appointments with licensed clinicians. The New York startup told Crunchbase News exclusively, in Crunchbase News's report by Mary Ann Azevedo. Jonathan Sabbagh co-founded Journey Clinical, which supports practices offering ketamine-assisted psychotherapy, and Edvard Engesæth co-founded Nurx, which provides birth control and other healthcare services online. They began building Siggy in late 2025.

This piece covers the investors, prescriber visits every few months, the Siggy Score, and insurance in all 50 states, including veteran care the founders say will stay free. It is for readers following Sabbagh and Engesæth, and for patients who want a licensed clinician and AI check-ins while keeping a therapist.

The deal behind Nurx And Journey Clinical Co-Founders

Village Global led Siggy's $6 million pre-seed, the New York company's first outside funding. Investors who had backed one or both founders include Albert Wenger of Union Square Ventures, Mercury co-founder and CEO Immad Akhund, and Cityblock Health co-founder Toyin Ajayi, through Coalition Operators. PsyMed Ventures, Mystic Ventures, and Gokul Rajaram participated. Akhund invested personally and is a repeat backer of both founders. Village Global general partner Amrit Rao told Crunchbase News by email that their experience building healthcare companies was a major reason he invested.

Sabbagh, Siggy's CEO, co-founded Journey Clinical and is now its executive chairman while leading Siggy. Engesæth, COO and a physician by training, was an early Journey Clinical investor and advised Sabbagh as he built it. He co-founded Nurx, which initially helped patients obtain birth control prescriptions and medication at home. He said Nurx reached more than 2 million patients and an annual revenue run rate exceeding $100 million before merging with Thirty Madison in 2022. They had considered starting a company together for years.

Why Nurx And Journey Clinical Co-Founders raised

Sabbagh told Crunchbase News that therapists and the clinicians prescribing medication often work separately. Patients may see a therapist weekly but have only a brief appointment every few months with their prescriber, leaving little time to discuss changes in symptoms or medication side effects. Siggy uses AI conversations and daily check-ins to gather information clinicians can review between visits. Engesæth said, "AI helps maintain the conversation and organize what patients share, so clinicians have a richer picture of the person that they're treating."

After two decades in finance, Sabbagh experienced burnout and was diagnosed with PTSD related to childhood trauma. He said ketamine-assisted therapy helped him recover, so he returned to school to study psychology at 38 and later co-founded Journey Clinical. The founders want the regular contact and coordination he had with his own providers available to more patients. Patients can continue seeing their existing therapists while using Siggy, Sabbagh said. A planned feature would let patients share information with other providers and involve loved ones in their care.

What the Nurx And Journey Clinical Co-Founders money

The founders plan to use the round to hire more clinicians and engineers, develop the software, and work on regulatory requirements. Siggy recently began accepting paying patients ahead of its public launch, and they will test the service with paying patients before expanding further. A patient answers history questions in a free AI conversation, then meets a licensed clinician by video. The clinician reviews that information, makes a diagnosis, and prescribes medication if appropriate. Between appointments, the patient can talk with Siggy's AI.

Each day, patients can report sleep, mood, medication, and how they feel physically. Those answers and wearable data produce a daily Siggy Score out of 100, visible to the patient and the clinician. Whoop, Oura, or Apple Watch can add sleep, activity, heart rate, and heart rate variability. The aim is to flag difficult stretches earlier, including when patients feel fine despite worsening sleep or other physical changes. A score change is flagged for a clinician, and weekly check-ins run the first eight weeks.

Competitive context for Nurx And Journey Clinical Co-Founders

Siggy accepts commercial insurance in all 50 states and is expanding into government insurance programs. Patients can pay directly, and insured costs vary by plan. Engesæth said insurance was a priority because many prospective patients cannot afford treatment out of pocket, and the founders say the service will be permanently free to veterans. "Pairing that vision with an insurance-based model makes the ambition about access as much as technology," Rao said. Akhund's longer-term aim is using AI to understand each patient's brain health well enough to detect changes early. "That's why I'm backing them again with Siggy," he added, "and why I'm excited to be in early on what they build next."

Journey Clinical still supports practices offering ketamine-assisted psychotherapy, with Sabbagh as executive chairman and Siggy's CEO. Nurx, which merged with Thirty Madison in 2022, had more than 2 million patients and an annual revenue run rate exceeding $100 million. Clinicians on Siggy decide whether to continue treatment or adjust medication, handle all medical questions, and, when appropriate, help patients taper off gradually. The founders said Siggy does not prescribe controlled substances and is not a crisis service. Patients can keep an existing therapist, Sabbagh said.

Open questions on Nurx And Journey Clinical Co-Founders

Siggy recently began accepting paying patients ahead of its public launch, and the founders next plan to test the service with paying patients before expanding further. Hiring, software, and regulatory requirements are what they say the round will fund. They stated no public launch date and no single price for patients who pay directly. Commercial insurance is available in all 50 states, government insurance programs are still expanding, and insured costs vary by plan. The founders say the service will be permanently free to veterans.

Whoop, Oura, and Apple Watch links are optional. A Siggy Score change flags a clinician for review, and weekly check-ins last the first eight weeks. Sharing information with other providers and involving loved ones is a planned feature. Akhund said he is backing the founders again because they aim to detect changes in each patient's brain health early. Siggy is testing the history conversation, the video visit, the daily check-in, and the score. Clinicians still handle diagnosis, prescriptions, tapering, and medical questions.
