Brooklyn Health

What Brooklyn Health does

Brooklyn Health is a neuroscience technology company that has built Willis, an AI-based electronic clinical outcome assessment (eCOA) platform aimed at solving what the company calls the measurement problem in mental health — the unreliability of existing instruments and review processes used to assess drug effects in CNS clinical trials. Willis automates traditional clinical review workflows through AI, standardizes mental health outcome measurements, enhances data quality, and includes open-source tools for digital phenotyping. The company is founded and led by CEO Anzar Abbas, a neurosurgeon/neuroscientist with a humanities background in the history of neurology, and the team of fewer than ten core members is cross-disciplinary, combining clinicians, engineers, product, operations, clinical science, research science, and design.

The company targets enterprise pharmaceutical companies and research institutions running CNS clinical trials as its two customer segments, addressing the pain point that manual mental health outcome review is error-prone and poorly standardized. Distribution is direct enterprise sales-led with global scope, and the commercial model is subscription/recurring, though specific pricing is not publicly disclosed and contracts are likely quote-based at the enterprise level.

Brooklyn Health is privately held, headquartered in Brooklyn, NY at 195 Montague St, and incorporated as BklynHlth, Inc. in Delaware. In May 2025 the company closed a $6.5M seed round led by HealthX Ventures with nine additional investors including Bessemer Venture Partners, Metrodora Ventures, Riverpark Ventures, Laconia Capital Group, Story Ventures, Everywhere Ventures, Hypothesis Studio, and Blue Falcon Capital. Use of funds is explicitly team expansion, Willis platform improvement, and accelerated commercial deployment with pharmaceutical customers. The company does not disclose revenue, patents, regulatory certifications, or named enterprise customer logos.

Direct peers

• Signant Health: Signant Health (formed from CRF Health and Bracket) delivers eCOA, ePRO, and clinician-rated outcomes for CNS and other trials. It is one of the established eCOA vendors Willis must displace to win CNS study mandates.
• Medidata (Dassault Systèmes): Medidata's Rave eCOA is the dominant industry-standard electronic clinical outcome assessment platform used across CNS and other therapeutic-area trials. It is the most direct incumbent competitor to Brooklyn Health's Willis platform.
• Clario: Clario provides eCOA solutions and scientific consultation for CNS and other clinical trials, including instruments validated for psychiatric and neurological endpoints. It competes head-to-head for the same pharma buyer and study use case as Willis.
• YPrime: YPrime offers eCOA and electronic data capture solutions for clinical trials with a focus on patient-centric data collection. It targets the same pharma and CRO buyers as Brooklyn Health for CNS and adjacent therapeutic-area trials.
• Clinical Ink: Clinical Ink provides eCOA, ePRO, and direct data capture solutions across CNS, rare disease, and other therapeutic areas. It is a direct peer for eCOA deployments in CNS trials.

Emerging players

• Medable: Medable offers decentralized clinical trial technology, including eCOA/ePRO, focused on patient-centric trial design. It competes for the same decentralized CNS trial sponsors but with a broader DCT scope.
• Castor: Castor provides an eClinical platform with EDC, ePRO, and eConsent modules used by pharma and academic sponsors. It overlaps with Willis on patient-facing data collection but is less CNS-specialized.

Broad incumbents

• IQVIA: IQVIA offers eCOA as part of its broader clinical technology and CRO services portfolio, leveraging deep pharma relationships. It is a broad incumbent competing for both technology and operational spend.
• Veeva Systems: Veeva Vault CDB and Vault EDC provide clinical data platforms used by most large pharma. While not a pure eCOA vendor, it competes for adjacent clinical-operations budget and integrates with eCOA workflows.
• Oracle Health Sciences: Oracle's Clinical One and InForm platforms include eCOA capabilities and serve the broader clinical trial technology stack at large pharma. It is a broad incumbent rather than a CNS-specialist.
