MSN-01: Case study

TruWell

From a half-working vibe-coded prototype to a production care app in one month, built around the patient experience the clinic wanted.

Mission results

From prototype to production care app: 1 month
A subscription business that didn't exist before: $0 → MRR
MRR growth since launch: Every month

01 / The problem

Where it started.

TruWell is a hormone telehealth clinic. Its patient base was growing slowly, held back by the technology available to it.

The care portal that came with its back-office EMR was clunky. It didn't fit how the clinic wanted to grow or the experience it wanted to give patients. The founder had a vibe-coded prototype of something better, but it only half worked.

The clinic also wanted to move to a subscription retainer model, and the old portal couldn't support it at all. Recurring revenue was stuck at zero.

02 / Constraints

What we had to work within.

C-01The EMR remained the clinic's system of record, so the new app had to integrate with it rather than replace it.
C-02Patient data meant full HIPAA compliance from day one, across the app, the hosting and the EMR integration.
C-03The prototype showed what the founder wanted but wasn't a foundation that could carry real patients.

03 / Decisions

Decisions we made.

01
Keep the prototype's vision, not its code
The vibe-coded prototype was a useful spec for the experience the founder wanted. We used it to understand the vision, then built a new production-grade app instead of patching something half-functional.
02
Own the experience, integrate the records
The EMR stayed the clinical system of record. The new Care App sits on top of it, so the clinic controls the patient experience without migrating its back office.
03
Build the business model into the product
The retainer model the old portal couldn't support became a core feature: subscription billing shipped alongside the patient features, with a revenue and onboarding dashboard so the owners can see growth as it happens.
04
HIPAA compliant from the first commit
Compliance was designed in, not bolted on. The app, its Google Cloud hosting and the EMR integration are fully HIPAA compliant, so the clinic could launch to real patients with confidence.

04 / What we built

What we built.

A production-grade, HIPAA-compliant Care App integrated with the clinic's EMR, covering the full patient journey: lab orders, secure patient messaging, appointments, prescription refill requests and subscription billing.

For the owners, a revenue and onboarding dashboard that tracks new patients and monthly recurring revenue.

TruWell Care App member home with refill, next appointment and membership status, labelled as demo data — Care App: member home (demo data, not real patient information)

TruWell lab orders page showing a paid order of three tests and how to get blood drawn, labelled as demo data — Lab orders (demo data, not real patient information)

TruWell secure messaging thread between a member, the care team and a provider, labelled as demo data — Secure messaging (demo data, not real patient information)

05 / Outcome

What changed.

The new app unlocked the subscription retainer model, taking TruWell from $0 in recurring revenue to MRR that has grown every month since. With a care app it was proud of, the clinic turned on marketing and has grown its patient base steadily since launch. Existing patients love the new app, and the owners watch the numbers climb on their dashboard.
