OUR PORTFOLIO

Backing healthcare from every angle.

Healthcare loses enormous value between detection, decision, and execution. We invest across six deployment theses in the companies closing that gap.

/01 The Great Convergence: EMRs, wearables, diagnostics, and wellness are all converging on patient-centered care.

/02 The Diagnostic Leap: Turning diagnostic abundance into timely clinical decisions.

/03 The Friction Purge: Removing administrative work end to end — not just drafting around it.

/04 The Device Renaissance: Next-generation devices where hardware and intelligent software converge to change what’s clinically possible.

/05 The Care Migration: Episodic, encounter-driven care is being replaced by continuous, data-driven guidance.

/06 The VBC Buildout: The plumbing that turns risk contracts into auditable performance.
