01

Platform Biology

The most defensible companies in biotech own repeatable biological platforms, not single assets. We invest where the platform, not the drug, creates durable value.

02

Diagnostics & Data

The next generation of medicine is predictive. We back companies using novel diagnostics, biomarkers, and biological data to redefine how disease is detected and monitored.

03

Therapeutic Modalities

From gene editing to targeted protein degradation, we invest at the frontier of modality development where scientific risk and return potential are most compelling.
