An angel investment fund at the intersection of medicine and technology. We write small checks and stay on as advisor to the founders we back.
(brand)
IdiogenicOsmoles is our medical-education brand. Its first product was the Joslin Chest Atlas — an early Apple App Store hit in the medical category. Other titles included Tick Doctor, a clinician and patient-centered tick identification app.
We did early work building the public-facing iOS apps for other names you might recognize, including MDCalc and the New England Journal of Medicine. Coming next is RobotParrot, a personalized post-shift audio lecture service for emergency medicine residents.
IdiogenicOsmoles sits alongside a small blend of other operating businesses across different markets — held together under Bramble Tree Property, LLC.
From the Empire State, re-planted in a land of southern oaks.
Before Empire Oaks existed as a portfolio, there was Bramble Tree Estate — a wedding and events venue that hosted hundreds of ceremonies on a piece of land we still tend. The Bramble Tree name carries forward through the family's operating business name and daily work.
