Endo Health: The Neohospital Starts With the Next Refill

Endo Health helps patients keep in touch between visits and coordinates prescription renewals for licensed clinicians to review.

Care that continues between visits

A patient who needs a refill may have to repeat what changed since the last visit, check whether a clinician reviewed the request and then call the pharmacy. Endo Health is building what co-founder Brian Yun calls a neohospital: a care service that coordinates those steps between visits. Its current offering starts with ongoing prescription weight-management care. [1][2][3]

What happens after the patient checks in

A patient can share how they are feeling by text. Endo brings that update and the treatment history together for a licensed clinician to review. If the clinician approves a renewal, the prescription goes to a partner pharmacy. Endo can tell the patient if the care team needs more information and provide status updates. [1]

That workflow keeps the patient’s check-in connected to the review and the next step. Licensed clinicians make prescribing decisions, and independent pharmacies handle dispensing. [1][2]

From one care workflow to a wider idea

Yun trained as a doctor before becoming a software engineer. He founded Endo Health with Chanwoo Park and Ian Ryu, and the team joined a16z speedrun’s third cohort. [3]

Yun wants care to follow up as a patient’s situation changes, then carry out the next steps once a clinician decides. Endo’s refill service puts one part of that idea to work. [1][2]

The bigger picture

For now, the work starts at a familiar point in ongoing care: a patient needs an update, a clinician needs the history and a pharmacy needs a decision. Endo keeps those steps connected. [1][2]
