Brellium

What do the three modules do?

The homepage describes AI Chart Review as reading every note before claims go out, Compliance as measuring notes against payer policy and internal standards with scores and audit responses, and Autonomous Coding as coding each encounter, catching under-coding and over-coding and keeping an audit trail. Fierce Healthcare names the system CortexLM. The vendor lists flags for safety risk, medication discrepancies and missed sessions, with resolution steps. Its listed specialties are ABA therapy, behavioral health, hospice, primary care, cardiology and pain management.

Founders and funding rounds

The About page lists four co-founders: Zach Rosen (CEO), Henry Kasa (COO), Alex Le-Tu and Max Katzman (head of engineering). Fierce says Rosen's own misdiagnosis, traced to a documentation gap, motivated the company.

The April 2025 Series A was led by First Round Capital and Left Lane Capital, with Menlo Ventures, Digital Health Venture Partners, Kearny Jackson and Necessary Ventures. The October 2026 round, led by Left Lane and First Round with Digital Health Venture Partners, rests on a Raising.fi piece that cites no primary source. Raising.fi gives no series label. Axios and Dealroom summaries call it Series B, and TechJack calls it Series A.

Who uses it?

The homepage claims "250,000+ providers", all 50 states and more than 100 payors. Fierce names Headspace, Rula, Grow Therapy, Hopebridge, Lightfully Behavioral Health and Talkiatry. Headspace is quoted at 99.2% provider compliance with documentation standards and Lightfully at 87% less chart-review time, both selected by the vendor.

What does the security page claim?

It says Brellium is HIPAA compliant and has completed SOC 2 Type I and Type II with Secureframe and the Johanson Group. The page also states a BAA with every customer, AES-256 at rest, TLS 1.2 or higher, US-only storage and an isolated S3 bucket for each customer. It says no PHI is used to train models. Subprocessors listed as of February 2025 include AWS, Azure, Anthropic and Google, each under a BAA. The vendor says it "integrates with your existing EHR" and names none.

Pricing runs through a demo request.

The verdict

The strongest match is an organization whose main exposure is a payer audit of therapy or behavioral notes, since every named customer sits in that field. The autonomous coding module is one of three, and the customer results on the site concern compliance and review time.
