Build in Public

Building Wellet

A designer. An AI engineering team. Zero traditional developers. This is the journal of how one caregiver is building the health tool she needed — in public.

Betsy Eble spent 20 years in healthcare UX, including designing the UX for Duke Health's first EHR. When her parents' health got complicated, she realized no tool existed for the person holding someone else's chart. So she started building one.

Article #2

Article #3 Drafted, posting soon

I Built a HIPAA-Compliant Health App in One Week for Under $1,000. Here's What It Actually Cost.

Not a flex. A reframe. And a conversation about who gets to build healthcare technology — and why it matters.
