A new vertical for healthcare platforms

Health Starts at Home.

Your patients book an allergist. Get an inhaler. Go home to the same mold, lead, and dust mites that made them sick. They rebook in 3 months.

Canary adds one step: test the home. Certified inspectors, HSA-eligible, results back to the referring doctor. The cycle breaks.

The Broken Loop

Treat. Prescribe. Repeat.

A patient books an allergist online. Gets an inhaler. Goes home to the same dust, mold, and contaminated water that triggered the visit. Books again in 3 months.

1

Patient books Allergist on a healthcare platform

Recurring asthma, chronic sinusitis, pediatric eczema — 40M+ annual searches

2

Doctor prescribes treatment

Inhaler, antihistamines, topical steroids. Treats the symptom, not the source.

3

Patient returns to the same environment

Mold behind walls. Lead in water pipes. Dust mites in HVAC. Nothing changes.

Cycle repeats

The patient rebooks. The doctor re-prescribes. Another transaction, same outcome. The root cause is never addressed.

The Fix

One new step breaks the cycle.

After Step 2, Canary nudges the patient: “Your allergist recommends a home environment test. Book a certified inspector.”
