Thesis
Biology doesn’t recognize the borders we drew through it. Neither does value. Healthcare organized itself around specialties. Patients never did. Marram backs the companies connecting whole-person health to long-term outcomes — and to the returns that follow.
-
01
Convergent care delivery
The models that treat one patient, not two charts — integrated primary care, co-located and virtual-first clinics, and whole-patient teams that close the distance between medicine and dentistry.

02
Diagnostics & devices
The tools that read the whole patient from any door — salivary and biomarker diagnostics, imaging AI, and point-of-care screening that finds systemic disease wherever the patient shows up.
-
03
Connective infrastructure
The rails that make convergence run — interoperability, shared records and data exchange, and the payment, benefits, and care-coordination layers that let medicine and dentistry act as one system.

Team
