Brellium

Brellium is a New York-based healthcare technology company building an AI-powered clinical and payor compliance platform. Its software audits 100% of patient charts against custom quality, coding, and billing standards in real time - flagging issues like copy-pasted notes, contraindicated medications, incorrect session lengths, and declining patient conditions before they trigger payor clawbacks or quality failures. Founded after CEO Zach Rosen's own costly medical misdiagnosis, Brellium serves behavioral health, mental health, ABA therapy, and hospice providers, and raised a $16.7M Series A in April 2025 led by First Round Capital and Left Lane Capital.
