Marram Ventures launches as an independent healthcare venture firm
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 the payment and benefits integration that let two systems act as one.

  • StageSeed to Series B
  • Initial checkUp to $3M
  • FocusOne system of care
Team

Like the grass that holds the dune, the firm is the structure beneath what grows. We understand before others believe — evidence underwritten, conviction held, beside the founder.

Two shores

Built between a lakeshore and a harbor — close to founders, close to the science.
