Company profile

researched Aug 2026

Bunkerhill Health is a San Francisco-based company that develops Carebricks, an agentic AI platform that lets hospitals and health systems build and deploy AI agents across clinical, operational, and administrative workflows. The company positions the platform as a single foundation on which clinical and operational teams can turn their own improvement ideas into production agents, rather than buying separate point solutions for each problem; its CEO frames the approach as an alternative to hospitals working with many vendors each solving one narrow problem.

Agent use cases described by the company span patient access, pharmacy, revenue cycle, care coordination, imaging, population health, and administrative domains. Examples include escalating clinically urgent cardiology referrals and rerouting misdirected referrals, compiling and submitting prior authorization packets for oral oncolytics and filing appeals on denials, issuing clinical documentation improvement queries for sepsis-with-AKI discharges, referring patients with reduced LVEF to electrophysiology, drafting confirmatory DEXA orders when an FDA-cleared bone mineral density algorithm flags possible low bone density on abdominal CT, sending colorectal cancer screening self-scheduling links, and distributing advance directive forms to older patients. Alongside operational agents, the platform embeds nine FDA-cleared clinical AI algorithms, including ones for detecting silent heart valve disease and assessing osteoporosis risk.

The company states that Carebricks is deployed at health systems including Cleveland Clinic, the University of Texas Medical Branch (UTMB), and Intermountain Health, and reports SOC 2 Type II certification, HIPAA compliance, and ISO/IEC 27001:2022 certification.
